Men's Chugach Heavyweight Zip-Off 3/4 Bottoms – 100% Merino Wool
How many times have you started a hunt freezing cold, only to be sweating by mid-morning? These heavyweight zip-off 3/4 bottoms solve that problem without making you remove your boots. Simply drop your shell pants, unzip the sides, and shed (or add) this insulating layer when conditions change. The 400 GSM 100% merino wool delivers serious warmth for Alaska's coldest days, while color-coded hook-and-loop closures make reassembly quick and foolproof in the field.
Why You'll Love These Zip-Off Bottoms:
The 3/4 length sits above your boot tops, eliminating bulk around the ankles where it interferes with lacing and fit. Full-length YKK side zippers with cord extensions are easy to grip with cold or gloved hands, and fabric backing prevents the zipper from touching your skin. White hook-and-loop on the right side and black on the left means you'll match the correct sides every time—no fumbling in low light. The large gusset allows full range of motion for climbing, kneeling, and stalking, while flatlock seams prevent chafing during long days in the field. At 16 oz (size L), this is substantial insulation that performs in the harshest conditions.
Why 100% Merino?
At 400 GSM, this is true heavyweight merino—nearly three times heavier than competitors' "zip-off" options that max out around 145-300 GSM. Pure Australian merino regulates temperature naturally, keeping you warm when sitting still and breathing when you're on the move. The fiber's legendary odor resistance matters when you're hunting scent-wary game, and moisture-wicking keeps you dry even during high-exertion stalks. UPF 50+ protection adds sun safety during those long glassing sessions above treeline.
Size & Fit:
Regular fit with room to move freely. Runs true to size. Model in black is 5'10" / 150 lbs wearing a medium. Designed as a mid-layer under shell pants.
