Requires some practice, but it's worth it. Overall, in my opinion, this is pretty good option for base layers under your track suit. Could the entry zipper extend down a little further to make getting in and out of easier? Yes. But I can almost guarantee you that those that have had problems with tearing or hearing rips when getting in and out of are doing so because they aren't taking their time or are putting it on like its their race suit and assume it can just be pulled whichever way without problem. It is VERY form fitting, but by design obviously to be as unobtrusive as possible. I'm 6-1, 170lbs - Tall, athletic build and the size large fits like a glove. The first time I put it on, I could hear a small tearing sound, but that's because I didn't know how it fit and just tried to throw it on. I've had it on about 5-10 times since and now that I take my time and put the right arm in first (where there's more fabric due to the offset zipper) I have not had a single issue with it since. This suit makes getting in and out of your race suit a breeze because of the foot and finger loops. Overall, for the price, I think it can run with the rest. April 14, 2014
Stitching fell apart in less than 60 days The stitching on one of the arms completely gave out in less than 60 days of use and washings. I'm very disappointed in the quality. I would expect more. I've had bicycling gear last me years and stay in good condition. This lasted less than two months. September 30, 2013
Needs better zipper, more airflow First of all, the zipper is way to short and cheap. First suit I got the zipper broke after only two wears. Most importantly, the zipper needs to go down lower. Taking off or putting on the under-suit if your sweaty is hard enough (actually, d+mn near impossible, it sticks to you like glue), but because the zipper goes down to above you belly button, putting it on/off is a contortionist's nightmare. I know soon, I'll be breaking the zipper or seam while wriggling like a mofo trying to take it off while sweaty (as I said, d+mn near impossible). Also, needs better airflow. Next time getting aerostar or dianese. July 22, 2013
Not ergonomic at all I am 6 ft tall with athletic build and this suit is almost impossible to get in and out of. Zipper doesn't go down far enough. I nearly dislocate my shoulders getting into it. Also fits very tight. I prefer a looser fit such as what dainese offers. I will order that next time. Last, I think it fits smaller than usual. Crotch area if you know what I mean. Dainese recommended large based on my size but I think Xl would be the right size. June 3, 2013
Great style and functionality This undersuit seems like a great piece! The fit is somewhat tight, still not have had a chance to test it on the racetrack! Will let you know about climate control features.... Saludos! May 22, 2013
nice piece with some thought put into it this is a well made under suit. it flows a lot of air and has some great features like the grip pads on the shoulders. the foot loops are a little big and would work back toward my heal but nothing bothersome. the side zipper is a good idea but unfortunately I have a messed up collar bone on that side so the zipper ended up right on top of it.

REV'IT! Excellerator Race Undersuit Very comfortable, it makes getting in and out of my race leathers night and day better. With the finger loop and under the foot strap there is no bunching up when I put on my leathers. The only gripe I have is if you are not careful when putting on this suit you can hear it tearing. Time will tell how well they hold up. March 11, 2013
A Bit Quirky This suit has (2) zippers, one across the chest and one at groin level. There is a full stop between them, meaning that the upper, 'get into it' zipper is much shorter than it could be. This makes getting the suit on more difficult than if it were made with a single full lenght zipper. I don't like this feature. I wear size Euro 50 leathers. I ordered this suit in 48; once on the size and fit are perfect for me. I am sure the seams are not going to last due to the degree of streching necessary to get in to it. The split zipper is a bad idea. I checked the 'recommend' box but...I'm not sure. February 4, 2013

Rob855: Each item on Revzilla is offered with a size chart. If you are interested in Dainese products, simply download the comprehensive chart. It gives every bit of info you will need to choose the correct size. You will need a basic understanding of the metric system. Some of the measurements are displayed in 'cm', that is, centmeters. Remember that one inch US is equal to 25.4 millimeters.
For example a Dainese men's one piece suit, size Euro 50 (US 40), has chest girth of 100.0 cm, which is 1000 mm. 1000mm, divided by 25.4 (millimeters per inch) equals 39.37 inches. Therefore a Euro 50 suit is about equal to a US size 39. Recall that Dainese cuts it race suits rather tight. I hope this helps you.

PeteFLUSA: I just got two undersuits and I found both were quite forgiving as far as size. I believe you have to look at how much surface area you need to cover, which can likely be roughly translatable to weight. I weigh 170lb and bought larges in both undersuits. I tend to fit size 44 US/54 Euro in race suit. A friend of mine who weighs 140lb and wears 42 US/52 Euro saw the fit and decided for a Medium.
I hope this is helpful!

Stevan P: We would suggest a size small based on your measurements. You definitely do not want the suit to be baggy. Aug 31, 2011
