We were trying to build the perfect pants to wear under waders, but we accidentally made the most comfortable cold-weather pants youve ever worn. Our Thermo 350 Pants arent just under-waders: imagine if your favorite sweatpants, your favorite joggers, and your favorite cold-weather pants had a lovechild. Theyre kind of like that. Constructed using 95% hand-selected New Zealand wool with a cloud-fluffy interior and a durable knit face exterior, these are performance underlayers that you can (and will!) still be wearing hours after the waders get hung up to dry.
95%, 20.5 Micron Merino wool and 5% spandex blended for 350 gram weight baselayer. 2 Jean cut pockets for ease of use under waders and rear zippered pocket. Stretch waistband with cordage adjusters.
