Buy with confidence, we will happily swap sizes for you.
Sitka sizing is comparable to New Zealand and Australian sizes - so if you wear a large in a work shirt a large in Sitka will generally be the right fit too.
Order the same size in base and outer layers, the outer layer in the same size is designed to fit over the layers that are likely to be worn underneath it.

Built for frigid winter sits, the heavyweight Sitka Core Merino 330 Half-Zip features the warmest-weight merino wool to keep you warm in the coldest conditions. Merino wool has an exceptional warmth-to-weight ratio to keep you warmer with less bulk and it regulates temperature through stop-and-go pursuits. Merino wool also resists odour to help minimise your scent, and Sitka's ArmorSpun merino wool outlasts traditional merino wool. And to prevent sweat from leaving you wet and cold, we added a synthetic interior that rapidly moves moisture away from your skin and through your system to keep you dry and warm.
When you’re hunkered down in frigid temps or hiking through mounting snow drifts, you need the heavyweight warmth of the Sitka 330 Series. The merino wool-blend fabric offers more warmth with less bulk and naturally resists odour when you’re on extended hunts. We also engineered it to be stronger than traditional merino. And since wetness is the biggest threat to warmth in cold conditions, we gave it a synthetic interior that rapidly moves moisture away from your skin and through your system.
