These are the flagship pants from the tamok series, focused on backcountry and powder riding, and are the final GORE-TEX PRO model. The 3-layer outer fabric is made of 70x160 denier 100% recycled material, durable enough for tough backcountry use. Used twice in 2022, selling because I lost weight. Please refrain from purchasing if you are overly concerned about condition, as these are used items. No claims, no returns accepted.
