Glassing is the coldest work in hunting: hours of sitting still on an exposed ridge, followed by a sweaty hike to the next vantage. The Glasshouse is built for exactly that cycle — 250 gsm merino that insulates while damp, with a quarter zip deep enough to dump heat the moment you shoulder your pack.

The face fabric is brushed for silence; no swish when you raise your binos. Thumb loops keep the sleeves anchored under gloves, the collar stands tall enough to meet a beanie, and the drop tail stays tucked under a bino harness.

It comes in one color — Timberline olive — because that is the one that works. Machine washable, hang dry, and it will not hold a week of camp smell the way synthetics do.

Field Reports From Verified Buyers

★★★★★ · Wore it 11 straight days

Late-season Colorado unit, single digits at first light. Wore this every day over a light base and under a puffy. Never once felt clammy after a climb. Eleven days, no smell. Merino magic.

★★★★★ · The quiet face is real

You do not appreciate a brushed face until you raise binos next to a buddy in a crinkly softshell. This thing is silent. Sizing runs true, thumb loops sit right.

★★★★ · Great layer, watch the cuffs

Excellent mid-layer for glassing sits. Only note: the thumb loops stretch a bit if you wear it as an outer layer daily. Granite Ridge repaired mine for the cost of shipping.
