The 509 Allied 2.0 Insulated Monosuit delivers full-body trail protection with premium materials, ergonomic comfort, and targeted insulation for high-performance cold-weather riding. Built with 5FLEX stretch shell and up to 400g of zoned insulation, it provides serious warmth without restricting mobility—making it ideal for aggressive trail riders in the harshest winter conditions.
With its fully seam-taped construction, PFAS-free DWR coating, and YKK® Aquaguard zippers, this suit is built to block out wind and moisture while maintaining breathability. Zoned insulation delivers up to 400gsm of quilted SynLoft and Aurora microfleece in key cold zones, while lower-bulk insulation in high-mobility areas keeps you agile. Add in F.I.T. (Float, Impact, Thermal) knee protection, internal suspenders, and 3/4 leg zips, and the Allied 2.0 Monosuit is your go-to for all-day, all-conditions trail domination.
