The Moto-D undersuit is an adult onesie (come on, they were so cool when we were kids!). The undersuit is made of an 84% polyester and 16% Spandex blend, making it ULTRA stretchy. Because it's so stretchy, I was even able to stitch the undersuit up when it tore during one of my crashes due to my suit coming apart! In regards to sizing, I am 6'3" and 205 lbs with an Athletic build, and I fit into a Medium perfectly. We have never had one returned for it being too small, definitely something to keep in mind when selecting the size that best suits you!
For those of us who wear leather suits or jackets in the canyons or at the track know how much of a pain, literally, it can be getting them off. The undersuit COMPLETELY defeats this, making suits and jackets slide off with ease. In addition, the fabric creates a barrier between your skin, helping to wick away moisture, keeping you cool and comfortable all day long in both hot and cold weather. Speaking of comfort, the MOTO-D undersuit has a two-way zipper that opens from either the top or bottom, so it's easy for men to unzip for rest room breaks. All in all, I highly recommend this undersuit, and if you still have questions email or call one of our resident gear experts for any help and or advice.
