Windproof and water-resistant fabrics protect you from the elements, yet remain breathable so you don't overheat during high-intensity rides.

After trying many different cold weather kit options (most being less expensive) I took the plunge on this one - Very Pleased. The construction, fit and comfort are top notch. Tight without being constricting. Able to layer under with a base and over with a snug jacket without restricting movement. Really a perfect product for me. Get one for next winter before they are gone!


Good morning - I’m trying to determine which size will fit me best and am between the SM and M. I have the Castelli Sanremo shortsleeve triathlon suit that fits perfect in a medium (and just ordered another). However, when I evaluate the sizing guideline for the Thermosuit, small seems to fit the measurements better, with the exception of chest. I’m 5’8”, 147lb, chest 38, waist 29-30, hip 37, inseam 32. So, is this Thermosuit designed for a skin tight fit to allow layering on top, or is it designed to layer underneath? Given that it is black, I generally opt for bright (more visible) colors in cold weather riding, so I’m thinking layer on top, but I don’t want to feel like to much sausage in too little casing. Thanks. Ty
