These are a great base layer for cold hunts or pair them with the core hoody and hunt the hot Texas summer. They wick moisture very fast and keep you dry when hiking. I definitely recommend these.

Look, I'm as cheap as they come. I've tried almost every brand of hunting clothing out there and if I haven't tried it, I promise I've spent countless hours researching it. I'm the kind of person that will spend 4 hours researching a $20 product and comparing it before a purchase. I can say with absolute certainty that Sitka is the BEST clothing line on the market. Not just hunting clothes, but best overall. Their clothes are cozy, durable, and designed to keep you extremely comfortable with minimal layers and bulk. You can buy other brands and replace them every few years, or buy Sitka and your set for decades if not life. Buy once cry once!

Bottom line is this isn't clothing, its equipment. More than that, it's equipment that could quite literally save your life in the back country. Once you realize that, the price is absolutely justifiable. I trust this company so much that I will buy their stock if they go public and I'd quit my job to work for them if they have an opening. That is how much I believe in Sitka.

These have become go-to base layer for most of what I do. I’ve hunted all over the country in these and not once have they let me down. Will be buying another pair soon!

Irreplaceable part of clothes, I wear them all the time. They breathe well and at the same time perfectly warm in cold weather. This is a great layer! Thank you Sitka for the amazing gear!

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.
