    Way better than Alpinestar

    Posted by Jack N on 28th Jul 2021

    I used Alpinestar for the past 10 years. I was skeptical when I ordered this undersuit on-line. Order without fear, it is better than the under suits from Alpinestar. I ended up buying another one at the race track this weekend during Mid-Ohio Vintage Days.

    Bodysuit stats: 99+ heat resistance, 22+ stamina and 5+hp

    Posted by Milli on 5th Jul 2021

    I was about to die at the track last week. I wore “summer” workout clothes to a track day at the end of June. By 8am after tech I was already suffocating in my suit from the heat. Then Me and my group went to the tent and bought MOTO-D undersuits. Let me tell you even though you feel butt naked and look like a 1970s porn star this is worth all the money. The rest of the day I was kept as cool as possible. I wasn’t getting as tired during sessions either so I was able to go the entire day without getting heat exhausted. I wear this on the street now to during the summer. It’s worth the money. It holds up well in the wash also, just use gentle cycle and air dry.

    Best undersuit ever, can't beat the price!

    Posted by Harry S on 1st Jul 2021

    I've had an A* undersuit for a couple of years that I spent $150. For less than half the price, the Moto-d suit is a far superior product. Easy to get on and off, full coverage, and really makes sliding into and out of leather a breeze. I wish I had known about Moto-D earlier, I would much rather have 2 or 3 of these than a single A* undersuit. Also, I bought it on Tuesday and it was at my door Wednesday afternoon. Can't beat that!

    The only undersuit to wear.

    Cost effective, durable, and leathers fall right off even when wet. No other suit performs like this for twice the price.

    Big Guy - 6'1" 245

    Posted by Matt Roth on 24th May 2021

    Super suspect of European brands for sizing (they all seem different) in same with Under-suits. Moto-D sizing is spot-on!! Not only does it fit, it fits perfectly, no bagging AND it's very smooth (like a sea otter!) so you Sliiiiiiiiiiide into your suit and even when sweaty (from a half hour session with Yamaha Champions Riding School at full speed in 88 degree New Jersey heat) it sliiiiiiiiiiides right out! This means I can more easily peel my shoulders out of my leathers myself if there's nobody around to grab a sleeve! I even have a bum right shoulder and I can still get in and out of my suit EASILY by myself! Less struggling means less sweating and swearing and lower blood pressure! More time to relax in the AC or under my Canopy Tent! Thanks Moto-D! Great Product and GREAT price! I can buy two for what the other guys are selling! Matt Roth Northern Virginia

    Awesome undergarment

    Posted by J Franklin on 6th May 2021

    This is my first one piece undergarment and it fits excellent. I am 5' 9", 170lb, 40" hips, 41" chest and 30" inseam. I used their size chart, which recommended a small, and it fits great. The arms and legs have a little extra length but do not bunch up on me anywhere. It makes getting the one piece leather suit a breeze to get on and off, even after a good stint on the track, producing much sweat. I also enjoy how the air movement through it feels like air conditioning, when wearing only that and a pair of shorts. It seems to be very durable so far, and would recommend it to anyone :) especially for the great price it is.

    Great Undersuit

    Posted by CB on 17th Apr 2021

    Got this undersuit for wearing underneath my 1 piece leathers. They work well as the other reviews all say for keeping you cool and dry which is great! About the only negative thing about this is the sizing. Make sure you read the size chart carefully which in my case said Medium and sure it fits height wise and arm and leg wise but if you like going to the gym like I do the chest is going to be a little on the tight side so maybe a good idea to go up a size. I mean it still works and does what it's supposed to but next time I would get a size Large.

    comfort and ease of suiting up

    Posted by Rudolf losch (Daphne, Alabama) on 10th Apr 2021

    If your in a hot environment and you sweat, you need these period. Leathers slip on and off. I'm in southern Alabama so its well proved to be worth it. My first suit has lasted years (5 plus) and I use them 2-3 times a month. They go thru the wash weekly. They work and look like new. Oh by the way I use them up North and they also help keep me warm.

    What a Cool Suit!

    Posted by Jay H. on 29th Mar 2021

    Hit the canyons on an 85 degree day. It did it's job tremendously. My core felt cooler, the sweat was very minimal and my ability to concentrate on my riding was improved as I didn't get fatigued. I would only ask that the suit start coming in different colors or possibly a different color zipper selection. Beyond that, I highly recommend it as it is 1/3 of the price of the big brand names and performed better.

    Great undersuit. I highly recommend.

    Posted by Pete C. (Stamford, CT) on 14th Mar 2021

    I wore this undersuit all day yesterday. I stayed cool and hydrated. I was wearing joggers and a tshirt under my race suit. I would get fatigued so quick. I highly recommend this suit for anyone looking for one. The material is breathable and it stretches with compromising the integrity of the suit. Thanks Moto-D.

    Perfect accompaniment

    Posted by Norman R on 14th Aug 2020

    Riding the back roads less traveled

    Posted by Freddy Flash on 23rd Jun 2020

    Hands down the best under suit I have found to date, at half the $$$ Most mornings are about 80-100 (looking forward to my upcoming mountain adventures:-) miles of smiles on tight bumpy back roads, and this suit keeps me cool and comfortable! 5 stars for sure! It would have been nice to have this suit 45+ years ago when I was still playing on the tracks of the country! So good that I just ordered another;-)

    The MOTO-D XL undersuit fits great for my body frame. ( 6 ft, 260 lbs). There was plenty of material and give in the suit not to feel like it was a compression suit.

    Undersuit review

    Posted by Jessica R. (Garland, TX) on 19th Jun 2019

    The suit is amazing and surpassed my expectations. I took my dianese undersuit to the track the first time and found it absorbed alot of the sweat and made me even hotter. This suit is wonderful I took it out to test on a 8 hour ride in 80-90 degree heat everytime I opened my jacket I felt like I was in air conditioning while sitting outside. The wicking is wonderful and super ventilated. I love this suit and will be taking this with me to the track from now on.

    I was skeptical - but...

    Posted by Mike Q. (Newburgh, NY) on 4th Jun 2019

    This thing works. Big Willow in dead summer is no joke. This thing kept me cool, but even more important was how easy it made taking off the top part of my suit between sessions or heats. Would buy again.

    MOTO-D "Cool-Tec" motorcycle undersuit

    Posted by Ron A. (Dearborn, MI) on 16th Apr 2019

    A comfortable undersuit. It was a perfect fit. It kept me cool and dry on a fairly hot day (85° to 90° Farenheit). My leathers slipped on and off easily. Only time will tell how long it will last, but as of now I would buy another and would recommend it to other riders.

    Long distance/multiple days

    Posted by Jeff G (Munich, Germany) on 21st Jul 2018

    I don't race but take up to 50 day riding trips around (generally) Europe. I wear this incredible suit under my riding suit and can wash it out in the shower after a day of sweating in hot weather. I can jeep my jeans and shirts for when I am off the bike cleaner much longer between laundry days (I HATE doing laundry). Plus, on long riding days, it is so much more comfortable and cooler than wearing jeans on a hot day.

    Great for hot weather

    Posted by Ronen B. (Los Altos, CA) on 22nd Jun 2018

    It's amazing what a difference a good base layer makes. Used the under-suit for a weekend at the track and it was way better than the Under Armor and cheap stuff I was using previously. Overall, very pleased.

    Could not be happier

    Posted by Rob S. (Cleveland, OH) on 17th May 2018

    Like the title says, I could not be any happier with this undersuit gear! Fit is perfect, comfortable and does its job. I went from using under armor 2 piece, so long sleeve upper and full leg bottoms, the one piece under suit is so much better fitting. Also the price is way better! I could buy almost 2 of these MOTO-D under suits, for the price of of the under armor gear I was using. Also I am located in Canada, the processing time and shipping was quick, I received the item 5 days after ordering, can't ask for more then that. Thanks, I will be ordering a second suit ASAP

    Best value for your money

    Posted by Cosmina (Brasov, Romania) on 19th Mar 2018

    I wouldn't spend my money on anything else! The fabric is exactly what I need, it stretches and does not get stuck on the velcro of my suit like others. The smallest size is perfect for me (I am very small and it was very difficult to find a suit that fits me). It's soft and makes it easy for you to get into your racing suit. It has two zip heads so you can open it from bottom to top too (this is a plus for men i guess). It is also very easy to wash. Thank you MOTO-D!

    Great one piece design!

    Posted by Kalanimoku K. (Graham, WA) on 6th Mar 2018

    I was recently wearing a 2 piece underarmor set and I came across the MOTO-D 1 piece undersuit and purchased it to try it out. After trying it on and off with my race suit. I would have to say it's totally worth it. The material is great, stretches very well. I like the well vented back for protector and hump. Double zipper front was a great idea. Not having the over lay of the 2 piece I recently worn is great! I noticed no pinching in those areas. Thanks again MOTO-D for another great product.

    Best undersuit on the market

    Posted by Brian F. (Atlanta, GA) on 26th Sep 2017

    One consideration would be to reinforce the knee area. Reason being is that a lot of times we take our leathers off in the pits but leave this undersuit on while we work on the bike changing tires or something else and we are kneeling. Having a little reinforcement around the knee area would help reduce the possibility of tearing the suit or wearing out the knees.

    Posted by Steven B. (NYST Loyal) on 14th Sep 2017

    This base layer is incredibly comfortable, you won't believe it until you are wearing it. Before I purchased this base layer i was wearing a 2 piece under armor set that cost me at least $30 more that wasn't nearly as comfortable and this blows that away in functionality (keeping you cool) as well. It is absolutely a game changer and I wouldn't hesitate to buy enough that you can make it a regular component of your gear on every ride wether worn under a suit or not. I am looking forward to trying the undercut for cooler weather when the temperature drops. To add props to the quality of the item the fellas from MOTO-D were on point hooking me up with the right size over the phone with my initial purchase and helping me get receipts and things that I needed after a crash that led to my gear being chopped off in the trauma unit. Good gear and great customer service.

    A must.....

    Posted by Dan N. (Clearwater, FL) on 8th Aug 2017

    You will never want to put your leather suit on without these, never. Lightweight, stretchy fabric is form fitting for all different body shapes. It also wicks moisture and sweat and dries very quickly. You literally slide in and out of your suit. Dual zipper let's you pee without taking the undersuit off.

    Posted by EUROROBBY on 20th Jul 2017

    I had an undersuit from another brand"Psy.. sk.." which was very good too. But I´m very lucky to have found this one from Moto-D because they made the offer to take it one number smaller which was a great tip. It fits awesome and feels great. Shipping was very fast and smart packaging. Great Service!

    The Best Undersuit On The Market!

    Posted by Sylvia S. (Sacramento, CA) on 13th Oct 2016

    I wear either the summer or winter undersuit under my riding suit when I'm toruing around Europe. Last year was 67 days of riding and just finished a 35 day trip. I can smell, sweat, whatever all day and then wash out the undersuit at night and it's dry the next morning. As I carry all my clothes on my bike, this lets my jeans/shirts etc only get used at night so they don't have to be washed as often which is a big plus. The two way zipper on the summer suit is really handy. Great design.

    Keeping my cool while it's smokin' hot.

    Posted by Terry J. (Lubbock, TX) on 21st Jul 2016

    Just gave the Coolmax Undersuit the maximum test...two sunshiny 100 degree track days in full leathers. It did a great job of helping me in and out of my leathers easier, and in the afternoon I poured cool water over the suit to provide evaporative cooling during each session. A real life-saver. Great product, fits perfect, just follow the guide.

    Stay Dry and Cool in the Heat

    Posted by Bruce A. (Santa Ana, CA) on 13th Jul 2016

    I bought this undersuit prior to a weekend Trackday event at COTA in July. Conditions at the track were sunny, humid and 100 degrees. The Moto-D undersuit allowed me to easily slip my leathers off and on between sessions. With a slight breeze or with the aid of a fan, the suit wicked perspiration away from my skin and dried quickly, cooling me down in the process. The size chart was accurate and the zipper worked smoothly. The suit has stirrups at the bottom of the legs, that I wasn't sure I would like, but they did prevent the legs from riding up, and they didn't distract me at all.

    Suit really works!

    Posted by Dave B. (New York, NY) on 27th Jun 2016

    As my wife and I are rather tall and right on the break point on the sizing chart, I called Julean before ordering. He recommended to go a size up because of our height and he was spot on! Thanks Jumean!! The undersuit is a quality product and adds comfort to the ride when donning leathers.
