This is the most versatile piece of Sitka gear I own. I wear these in the mountains chasing elk in Sept through the whitetail rut in November. They keep keep me warm in the mornings and evenings as the thermals change but don’t burn me up during the day. These are the first thing I pack on every trip. Whatever you’re buying, add these to the list.

Fit is great per the Sitka size chart. Fit is snug as a long underwear base layer should be but not overly snug. This product seems more durable than similar products on the market and I believe posses the scent control qualities it claims. I would definitely recommend.

This is my favorite base layer and my go to for 95% of my hunts. These core light bottoms do a fantastic job of regulating temperature and moving moisture away from your skin. This is an incredibly versatile piece that I wear under waders chasing waterfowl, as my first layer chasing whitetails and turkey in the midwest, and in the high country on an early season mountain goat hunt.
