I bought my first 1 piece suit and found it difficult to get out if it once I was done riding. This base layer makes it a piece of cake to get out my 1 piece suit.

Awesome Product!
The Alpinestars Summer Tech Race Undersuit is an awesome product because it actually does what it is supposed to. The material offers enough compression to provide support to your limbs and help reduce fatigue as well as offering a generous amount of air to pass through and cool you down on summer rides. I am 5' 8" and 140lbs, so the Small size fit me perfectly. I wear this with the Alpinestars Motegi suit (size 48) and the perforated leather works well in conjunction with the undersuit to make riding with leather bearable in 90 degree weather.

Great Undersuit
I am 5'9, 155lbs with a 39" chest and large fits me just about perfect (snug)<br><br>This undersuit makes putting my race suit on and taking it off a breeze (especially on those hot and sticky days I could not imagine not having it)<br><br>The moisture wicking really does work, this suit does a great job at keeping you dry on the sweaty days as well. The suit zips from both the top and bottom (you can make a bathroom run without taking off the entire suit!)

Feels like I'm wearing nothing at all! Nothing at all!
I'm 5'10'' - 150lbs - 36'' chest, and a medium fit me pretty well. A small probably would have fit also.

The fabric is thin and light, and allows me to maneuver into the suit with a back protector with no problems (Dainese Laguna Seca Pro - Size 50). It also does a very good job wicking sweat and keeping me cool, as advertised.

Warm weather rider? You want this suit!
I live in the tropics where temperatures exceed 32 degrees centigrade all year round with high humidity, so cooling is very important to me.

If it is to you as well, you'd do well to use this suit.

Fitment is great for my 6ft frame in size L

First of all, the material is sheer and has a very nice feel on your skin.

Things get better when you start riding. The benefits of its moisture wicking feature can't be overstated. This inner suit kept me cool beyond even my highest expectations (combined with my Spidi Track Wind Pro).

The more you sweat, the cooler it gets. It's almost amazing how well it works

The material is very sheer, which raises doubts about longevity (I am probably overworrying, the feel of the material is a plus and I'm sure alpinestars are capable enough to make a durable undersuit out of it) but after its first track day and wash, its basically like brand new. The stitching however, is high quality and I have do doubt the seams can hold for a long time

As an added bonus you get some nice cosmetics with the little alpinestars logo on the front and wording on the back

And of course its absolute icing on the cake that even when soaked with sweat after a 1 hour ride to the track, 2 hours at the track, and another hour home in cloudless 34 degree weather with 100% humidity, that the leathers just slide off your body in 20 seconds (probably the other big reason why if you havent already bought yourself an undersuit, you should do it right now)

Great product and very highly recommended if you ride in any kind of warm weather

Great Idea to Protect Leathers!
This particular undersuit looks and feels great out of the box. Material is remarkably smooth and confortable. Fit was good for me to: I am tall and lanky at 6'1" 170lbs and the large was perfect. The stretchable fabric makes the fit forgiving, though if you have large arms or legs, this product may not be right for you. My only concern about the durability and cost-effectiveness. I don't believe this will hold up in too many washings - make sure you win a few races with this thing on to make up for the cost, especially if you tear up the outside of your leathers often with falls!

Great quality from A-Stars, but not the right thing for my purpose
First, let me say that the quality of this undersuit is excellent as expected, and it's fairly easy to get on & off, and is comfortable to the skin. HOWEVER: I bought it for the purpose of making it easier to slip into & out of my 1-piece leathers, which although the ad suggested this would help with, it does not for me. It is not slick enough material to really make any difference in ease of getting into & out of my suit. I have always worn a long sleeve compression shirt (by a very popular sports clothing brand that would be a synonym of "Below Protection"). That material truly does make it easy to get into and out of the suit; sweating or dry. Bottom line is that if you just want an undersuit that protects you from skin abrasions from rough spots inside leathers, this undersuit would be perfect, but in my case at least, it's not the thing I need.

Great!!!!
I wear this suit under full leathers. It makes it much easier to put on and take off.

I am 5' 10 , 200 lbs and 49 in waist and wear size XL. Fit is very good, material is very stretchy.

I wash the undersuit in cold water after every use. It gets hot in Texas.

This tech race undersuit is quality made and very easy to put on and to take off. It is seamless and form-fitting so that I don't even notice i'm wearing it under my race suit, and the light material does a great job wicking away sweat. The two-way zipper is great for ventilation after a track session or if you need to zip it up to use the restroom. Definitely recommended.

As the weather in Brazil is mostly warm throughout the year the summer tech race undersuit fitted really well to my needs on the road or track. You can actually feel when the suit is working on your body to provide a cooler sensation! It worked great everytime I wore to ride and it definetely serves its purpose! I do recommend this item!

I purchased an Alpinestars race suit and was told these undersuits where the way to go and they where right certainly makes getting in or out much easier plus the breathability makes it much more comfortable. I had purchased some inexpensive shirts that theoretically was similar NOT. This suit is well made and very comfy a definite recommend.

Since I have all leather gear now, I'll want something that can fit smoothly & snug underneath all the leather that I'll be wearing. Not to mention something that will help keep my body cool while under all that leather. A lot of good reviews about this product, I don't think i will be disappointed when I get the opportunity to try it out for myself. Alpinestars has yet to disappoint me so far.

Aloha! Which size would you recommend for the Alpinestars Summer Tech Race Undersuit to wear on track days? I'm 5'8", 190lbs, 40 inch chest, 36 pant size and 30 inch inseam. I'm looking for a suit to provide proper compassion, but without restricting my breathing when in a tucked position.

Mahalo,
M.
A shopper on Apr 10, 2014
BEST ANSWER: I'm 5'11" 150s 33" inseam and I were a size medium. It is suitably snug without binding. The material is very stretchy but is lighter than a lot of the compression clothes I wear cycling. I suspect a large would be called for, although the legs might be a bit long. Probably not an issue because the material is stretchy and comfortable against the skin so a little bunching at the bottom wouldn't matter. You definitely want the undersuit snug so it helps you slip on your leathers without binding. This one does that very well
Which size should I get if I am a size 52 on a Motegi 2-piece race suit?
A shopper on May 12, 2014
BEST ANSWER: I wear a Spidi leather suit size 50 and I wear a size Medium in the Tech Race Undersuit. For reference I'm 5'11" and in the low 150s. Suit is properly snug without being too short. The off-set zipper at the collar is a very nice feature.
Hi mate. I have an Alpinestars Atem suit USA size 40 (was a little snug at first but now fits like a glove). What size do you reckon would be the go? Thanks. Matt
A shopper on Dec 15, 2014
BEST ANSWER: If 40 is the chest measurement that is a men's medium. You would be 5'8" to 5'11 and maybe 150 - 160 lbs. Sorry you will have to do the conversions. If you are bigger than that then I don't know what the 40 is - Euro sizing? I think this question is better directed to the manufacturer or solved by google.

I am "medium" sized but I feel much more comfortable in a "large" suit of this type (skin tight suit), even if it is then a little baggy. So I would go up a size unless you are really squeezing into a race suit. BTW a tight fitting lycra suit works well under a wet suit also, if you are a surfer.
Hi, just trying to figure out the best size to get. I'm 175lbs, 5 ft 8 in, 36inch waist, 42-44 chest, and a 30inch inseam. Do you think a large would be too big? I'm not as concerned with snugness to help with rider fatigue as I am with just overall comfort. Thanks charlie
charles b on Jul 1, 2014
BEST ANSWER: Hi Charles,

I am 5 10.. 220 lb.. about the same on the chest as you but waist is 38.. I bought large and it fits perfect..
When I bought all my stuff through revzilla; I used the charts and the result were perfect..

Really dont know what to tell you, if I may suggest; take large ..

Cheers
Ali
To whom it may concern,
Not sure which would be the correct size undersuit for me?
Im 180cm's tall and weigh 154 pounds.
My chest size measures 38 inches or 97 cm's
Which size undersuit would best fit me in the Alpinestars Summer tech suit.
Yours Sincerely
Ion Siskamanis
A shopper on Jan 19, 2014
BEST ANSWER: I bought size medium suit last riding season. I like the suit very much. As for size, I'm close to the same weight and chest as you but about 6 inches shorter than you. For me, the medium suit's arms and legs are about 5-6 inches longer than I'd like them. For your 73 inch height, the medium suit should fit great.
I was wondering because I can't tell from the picture but even though the description says that this suit is also available as a 1-piece, does that mean that the top and bottom of this suit are detachable to make the top by itself and the bottom as well? Or is the 1-piece option a completely different product on it's own page? I'm a little confused.
Allen C on Dec 25, 2013
BEST ANSWER: The option you see in this page is a 1 piece only. You can buy the top and the bottom separately through other pages. Great product by the way.
HOW DO I CLEAN IT?
A shopper on Sep 17, 2015
BEST ANSWER: i just wash it in cold water with the rest of my black clothes. All in together with your recommended usage of powder on the box.
Put washer on delicate cycle and let the washer do the rest.
do not put garmet in a dryer, just let it air dry and try not to hang it on a line. try and drap it over a clothes horse or some thing like it. i have had mine for a year now and machined washed it several time and had no dramas.
best of luck.
What size do you recommend, I use a Dainese 52 size race suit which fits ok (maybe a bit snug on upper body and loser on bottoms and legs)?
Alejandro m on Mar 9, 2014
BEST ANSWER: I would recommend a size medium if your suit size is 52. The base layer should be tight, this helps ease muscle aches during long hours on the bike. Its a great cooling material easy to slip on and off.
Hi, Trying to figure out the size, I'm 5 ft 8 in, with a 30 inch inseam, 42-44 in chest, and 36 in ch waist, and weigh about 175. Tried to look at other answers?
A shopper on Jul 1, 2014
BEST ANSWER: I think a Large should work...
I am 5"11, 32" waist, 44" chest, 170lbs, and a large fits me nicely. There is some stretch to the material.
Hi, I have a 52 race suit, I am 175 Cms high an d weigth 71 Kgs what size should I buy?
Aldo B on Mar 18, 2014
BEST ANSWER: Well it all depends on if you will be wearing back and chest protection on the inside of the suit. So if you are a 52 & don't run back and chest protection, your an idiot. However if you do have a brain and use both go one size up
