Material is top notch and allows my body to breath pretty easily. The arms fit a bit long but nothing too bothersome.

My wife bought this for me as a secondary for my Llano QZ. I switch them out daily to air. After a few days, I smell like an old milk in a hot truck. The shirt does what it says. It doesn't retain the majority of my odour-de-Chad, thus I smell less, but at 10 to 20 foot miles a day, nothing can wick away that kind of scent. Only downside is the fabric catches on brush easily. Still a 5 star shirt.

As an outdoor enthusiast, I love testing new gear. I reached out to FL to order some clothing and start putting it to the test. Here is my review:
First, ME: Bird hunting nut. I hunt pretty much all game birds that are offered in Ontario Canada -meaning, I see just about anything from waterfowl and doves to wild turkey and upland birds, I'm in the boat or the field as often as I can. I like to invest in quality gear that keeps me comfortable when I'm outdoors - be it hunting, hiking, or camping.
I got my Wick 1/4 Zip and have put it through a few of my more "common scenarios" during this time of the year (Mar-May) and given it a bit of field time in order to give a bit of my initial feedback on it.

BACKPACK HIKING: When worn under a small mid-layer it provides ample breath-ability and wicks away sweat from your body. I typically wear it under a mid layer puffy style coat and carry a 30L backpack on. The 1/4 zip is great to air out as my core temperature becomes elevated. Dried out quickly and remains pretty much odorless.
TURKEY HUNTING: I wear it on my trek to the blind and when partnered with the Kiln it has routinely provided me with the heat i needed in the early morning.
WORN UNDER RAINCOAT: I also wear it on walks with the dogs - one instance was to see how well it performed under a GORE-TEX raincoat. It was pretty great. It was a mild 5 deg C damp and rainy morning and the Wick was enough warmth to keep me comfortable and it was a great paring under a small raincoat. *I really liked this pairing. I've worn this numerous times since and it's pretty comfortable.*

All in all with this base-layer, the Wick is a great lightweight next-to-skin garment that is great for staying warm (or cool) and it Wicks the moisture away quite well.
I chose to pair it with the Kiln and the Furnace as a layered system - my findings on them will follow when I get more field time with those other products.
Bottom line - I recommend this shirt as a great base layer. I sweat a lot in my aforementioned field testing of the Wick, and as many have mentioned already - little to no odor and it dries extremely fast. It's a solid product. I am quite happy with it.

Extremely lightweight and keeps you cool for those early season hunts, dries quickly.

This was my first, first lite product. I'm a fan of merino wool already but this shirt hits the mark. It's great quality, and fits decent. I like the vented material under the arm pits. I'm an in between size. Between large and medium. Fits a little loose but I'm okay with it because I think a medium would be snug or closer fit. I bought the fusion camo which was recommended by the first lite staff for where I hunt in the Northeast. I have not field tested yet but I'm sure it will do just fine. The only thing I wish it had was a higher neck line. I knew that when I bought it but still gave 5 stars.
