Merino Weight By Conditions
| Conditions | Merino weight | Why |
|---|---|---|
| Long hikes in, 30s F | Lightweight merino (about 145 to 150 g) | Moves sweat fast on the climb; add warmth on top when you stop. |
| All-day still-hunting, 20s to 30s F | Midweight merino (about 200 to 250 g) | Enough warmth to wear alone on the move, light enough to layer. |
| Long glassing sits, teens F and below | Heavyweight merino (300 g and up) | Holds warmth when you stop moving for hours. |
| Cold mornings, warm afternoons | Light base plus a heavier hoodie in the pack | Two thin layers adjust better than one thick one. |
The Base Layer Is One Piece of The System
The cold-weather layering guide covers insulated mid layers and vests, and the cold-weather rain jacket guide covers the shell that keeps it all dry.
Frequently Asked Questions
Why merino for a cold-weather elk hunt?
Merino keeps much of its warmth when damp, resists odor over a multi-day hunt, and moves sweat off your skin on the climb so you are not chilled when you stop to glass.
What merino weight do I need?
Lightweight (about 145 to 150 g) for hard hikes in, midweight (about 200 to 250 g) for most cold-weather days, and heavyweight (300 g and up) for long, cold sits. Many hunters carry a light and a heavy piece and swap through the day.
Is merino durable enough?
Pure lightweight merino can wear through at pack straps. Blends with a nylon core add strength.
Do these base layers come in women's cuts?
The Sitka Core Merino 330 Hoodie has a women's version with their own button and price.
