Great product!

Using this suit for 1 year in enduro riding and found its perfect, because it dries very fast and you lose your sweat and heat insanely fast and it feels comfortable. At winter i recommend to use something non-synthetic (cotton based), but during summer its best choice for quality and money! Very happy with it! Btw using extreme racing Thermal base layer too, and its great too, i

No Brainer!

This is my second one piece under suit from Extreme Racing, these represent extreme value for money, they fit well and are very comfortable, makes putting on and taking off your leathers a breeze in hot weather, I decided to purchase Extreme Racing's new design for summer use although not used in anger yet having tried these on they appear to feel cooler and with a new design collar they're less intrusive around the neck. I would recommend this product because they compare favourable against more expensive and other well known brands, great customer service and fast delivery from these guys!

Excellent product

Really impressed with the base layer suit - exactly what I was looking for and really good value compared to the other products on the market. Will order a 2-piece set soon for those long WE away!

2015 Pro Undersuit

I've been using undersuits under my race leathers for decades and have everything from Proskins to Extreme Racing and I have to say the Extreme Racing suits do work the best in hot conditions and survive wear and tear better than their rivals. The new 2015 pro Undersuit was purchased to replace my 13-15 year old Extreme Trackday suit which is still useable, but the new suit is beautifully made and a fair leap in technology, you do feel the sweat just 'wick' off your body. The quality of build puts their rivals to shame. Highly recommended. J
