The Base Haven 1/4 Zip and bottoms are now my go to base layer system. They are incredibly comfortable and very warm without the bulk. They also breath very well and quickly gets rid of any sweat that may happen on the walk in and the climb. I highly recommend the Haven Base layers.

I bought this set for hunting but didn't pull the gun till at the end of season, when I tried the shirt on my wife stated that looks awesome, you could wear that out to dinner. I have worn this shirt a couple of times now and I agree it is very warm for how light it is. I love this suit which is no surprise, Pnuna makes fantastic stuff, I believe it is the best out there.

Awesome for, super warm base layer

This is the most comfortable item I have ever purchased. I go out of my way to find an excuse to wear it. I love the soft inner and the feel of the outer shell. I would recommend this to anyone. Very warm by itself or layered under a jacket for extra warmth, They hit it out of the park with this one.

Very comfortable, not clingy and not sagging, just right re fit. Very nice material and should layer very well.

Very comfortable... Particularly impressed with the neck... Doesn't irritate. Nice warm comfort... And it's resistance to sweat outdoor makes it wearable for 2 maybe 3 days without stinking!
