Core Lightweight

These fit perfect - loose (don’t feel like they are compressing you) but they stay in place. The weight/warmth is exactly what I was looking for - wore them hiking in many different temps from 5 degrees to 40 degrees F.

Core Lightweight Bottom

I bought the bottoms and the top for my bf for for Christmas, and he loves them! Wears them under his hunting clothes and even sometimes wears them under his jeans for work! Super warm!

Great bottom baselayer

I chose this weight because of the dynamic nature of my public land hunts. These kept my temperature regulated while on the move, and warm during mid-season temperatures.

Long Underwear

They fit great and keep you warm. I’m not entirely sure why the camo pattern is necessary, though—these are meant to be a base layer. The camouflage would only really come in handy if you planned to go hunting in nothing but your underwear. ”

Great stuff

I bought the Sitka Core Lightweight Bottom for early-season hunts, and it’s quickly become one of my favorite base layers. Super comfortable right out of the box — the material is soft, stretchy, and fits really well without being too tight. I’ve worn it on a few hikes and hunts already, and it does a great job wicking sweat and keeping me dry. Even after long days, it doesn’t hold odor thanks to the Polygiene treatment. It’s light enough to wear on warmer days but also layers easily under other gear. Definitely worth the investment if you spend a lot of time outdoors.

Great base layer

Wore these out in the spring on a couple really hot days under the mountain pant kept my dry and reasonably cool would also be great in the late season hunts under the heavy bottom as another layer. Feel like these run a bit small though.

This is an added pair.

This is an added pair. I’ve worn this model many times on cool hunts (18-30 degrees) and can keep surprisingly warm. These are thin and light. Need to peel them off once the morning wears on because they can get too warm. I hunt mid October in Colorado. Keep in mind we don’t experience humid cold. But I’ve left my heavier sets in the duffle and opt for theses. True story.
