Fits great I love that they make an option without a hood. A good base layer, this, and a jacket will have you ready for must about anything; add in a puffy later for glassing or long did and I can't imagine you'll need much else.

The Klamath Quarter zip is very warm. The material is soft and the peice fits well. I ordered a Medium. I am 6 ft and 155 lbs. The torso fits well. Atheic cut. But the sleeves are longer than I expected and bunch up around my wrist. I would want the sleeves to be about 3 inches shorter. I also ordered the Dry Earth color and it is a much darker brown than I expected.
I would not layer more than one peice underneath without ordering a size up.

I have gear and clothing from EVERYONE out there and this QZ Klamath and the hoody version are the best gridded fleeces I've ever owned. The old Patagonia R1 was my go to for years and years but FL has come through again with the ultimate piece! I have every solid color in the hoody version plus cipher and plan to get a couple more of the QZs. I live in Colorado at 8,700 ft so I wear these things year round almost every day. They're amazing. Super nice next to skin but still roomy enough to accommodate layers underneath. Perfect cut, styling and design. Don't ever get rid of this one FL! Fit note: The sleeves are pretty long on this piece and don't come with FL's ubiquitous thumb holes unfortunately. Not a big deal but given how long the sleeves are and the fact that I'm used to having the thumb holes in all their other tops, it feels like a bit of a miss. I could have easily sized down to a L for a form fitting layer next to skin but like the ability to layer underneath the XL and it's got good stretch to it so it won't hang on you like a sack or look baggy. the sleeves, while long, are cut nice and trim and stay out of the way nicely when drawing my bow too.

I wear the Klamath like I would a hoodie (minus the hood of course). Its just a fantastic piece to kit! It’s warm, yet breathable, very soft, and is perfect for sliding the sleeves up to your forearms. I wear this with a merino t shirt underneath down to about 50 deg; any colder and I’ll throw a jacket over it and use it for insulation or layer more underneath. Great fall weather weight. I wear it to go workout, or walk the dogs, or sit in the stand, or for scouting. When scouting/stalking you could it down below 50 deg. The only downside is it doesn’t block wind, such is the tradspace for being breathable. That said, I still wear this all time! I purchased a 2XL after reading some of the reviews that had this a bit tight. I usually order an XL, which I think have worked great too, but with a more athletic fit. That said, it fits me in the shoulder about perfect, but it’s about an 1-2” long in the sleeves and down the back (like I said, the XL would have been great too, but I like my hoodies a bit baggy). Overall though, I love it. It fits great to throw a base layer underneath and get our in the woods!

Light, warm, breathable layer. Perfect over the kiln hoody while wandering in late rifle season.

The Klamath quarter zip is amazingly versatile and my favorite piece for September antelope through November/December elk seasons. It takes the chill off on early mornings during early season hunts and during the late season it is the perfect top layer for hiking through the backcountry and in below freezing temperatures it is warmer than it has any right to be.

Awesome mid layer to have for late season elk. Can't wait to try it for cold mornings in CO during archery season!

This fleece is very comfortable. It’s light weight yet keeps me warm in 20 degree temps when paired with the sanctuary jacket. In warmer temps, this fleece pairs well with a lighter weight outer layer like the catalyst jacket. Great all season addition to my hunting attire. I ordered the same size as my everyday shirts and it was a perfect fit.

I purchased this for an additional layer in the cold. The hunting season ended up being unusually warm during the day (45-60 degrees) with cold mornings (20-30 degrees). It worked perfect with just a tee and shell jacket for the cold morning then alone as the day warmed up. I am a larger framed guy so have to get the XXL and it fit great except the sleeves were 6 inches too long. This was the only negative I can say. Very comfortable allowed great mobility. I will also be using it for outdoor training during the winter months and SAR operations. It is thin enough to be worn under my uniform and give a layer of warmth.

I’m 5 foot 10 220 got a XL and fits good over 2 layers fits perfect tight but not to tight sleeves are little long but not that bad been wearing this as outer layer over base and middle layer with a heavy vest and no jacket in mid 30 degree weather have been very happy with it so far
