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.

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 buy
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.

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.

XL fits 6'4" 180-200 lbs
Amazing product and business to purchase from. got one for me and my brothers birthday (who also rides) and we love it because it's snug and tall enough for us to fit. Zipper is cross the chest Anna makes it easy to get into and out of when you're all sweaty. keeps you really cool too. Thanks for the excellent customer support!

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.

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 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!

Do not overheat on the track anymore!
First time I wore this suit it was 90+ degrees out. This base layer kept me cool and dry all day.
