Patagonia – Men’s R1 Pant | Lightweight fleece pants designed for warmth, stretch, and comfort under waders.

The Patagonia Men’s R1 Pant is the lower-body companion to the legendary R1 topbuilt for performance and comfort in cold fishing conditions. Made from a stretchy and breathable 6.8-oz polyester/spandex fleece (with 41% recycled content), these pants offer a snug but non-restrictive fit that works exceptionally well under waders or rain pants. Their high-wicking, low-bulk construction helps regulate temperature and moisture during long hikes or aggressive wading sessions.

With an elastic waist and internal drawcord for secure fit, plus two low-profile front pockets to store essentials, the R1 Pant is both practical and minimal. Whether you’re trudging through icy streams or layering up on chilly mornings, the R1 Pant offers reliable warmth without getting in the way.
