We were trying to build the perfect pants to wear under waders, but we accidentally made the most comfortable cold-weather pants you’ve ever worn. Our Thermo 350 Pants aren’t just under-waders: imagine if your favorite sweatpants, your favorite joggers, and your favorite cold-weather pants had a lovechild. They’re 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.
