Spidi Rider Undersuit 5 5 1 1
I use this every time under all my suits! The first time I saw this I was intrigued. The sole purpose of this nifty piece of gear is to ease in and out of something that used to be a two person job, Leathers are made to fit tight. It's what holds your armor in place in the even of a crash. Yet tight fitting one-piece leathers can be a bear to get into and even more troublesome (sometimes impossible with out extra help.) This garment mitigates the friction caused my sweaty skin after a hard hot ride and makes it a snap to get out, When on under the leathers I have not noticed any heat gain by this extra layer. The light and fine mesh breathe easy. No more cotton t-shirts that soak and heat you up. Freedom! And its easily washable, although I would recommend using Sport Wash to remove the funk that high tech wicking sports gear is susceptible to. Worth every penny! I sized down one size to keep this tight against my skin and avoid any uncomfortable folds or gathering between me and the leathers. If I were to offer one suggestion for improvement, it would be to add a stirrup at the ankle. Occasionally sliding into my tighter suits the fabric would ride up my leg requiring me to reach up inside my suit to pull the fabric down straight, May 9, 2015
