As others eluded to, this product has great warmth to weight ratio, and the antibacterial treatment make it a great addition to my hunting clothing. The reason I didn't give it 5 stars? The sleeves! The cut of the sleeves are crazy- long. It's as if they are designed to be thumb loop sleeves but someone forgot the thumb loop--3 extra inches of material! If it was worn for fashion I would probably send it back, but since it's a solid piece of back- country layering, I'll hang on to it!

Great piece for cold days. I wore it from November archery in my tree stand through February squirrel hunts. Taking it out west for elk next year

This Fleece layer has been a great item for my Southern pursuits. I typically use it as my outer layer in most cases, but recently I have used it over my 150 aerowool crew short sleeve. It does a great job of breathing during my long hikes in, and seldom smells even after many uses in a row.

I have this shirt in both quarter zip and the hooded versions. Absolutely one of the best base, mid and outer layers (depending on temps and weather) I have ever worn. I purchased the black, dry earth and conifer colors. Several years ago I deducted that the best cold weather gear must be hunting gear. After all, hunters are out in the cold, snow, rain, wind, walking, climbing, sitting, sweating, etc, etc. Therefore, I only shop at stores that offer hunting apparel. However, I am not a hunter. I fish a few times a year, but I wanted clothing that kept me warm and dry in the winter and cool in the warmer months. First Lite is at the top for me. This shirt provides warmth, no stink fabric and exceptionally quick drying fabric. If I shovel snow or work up a sweat hiking or other outdoor activities, this shirt is perfect. It never leaves me cold or clammy after exertion or sweat. Great for travel, skiing, casual wear, work, school or other activities. I know this review is somewhat opposite from others outdoor experiences (mainly hunting), however I wanted folks to know that these garments perform well with all outdoor activities. The solid colors offered go with almost every clothing combination I can come up with. Exceptionally satisfied with First Lite.

Just bought this and received it yesterday. Initial thought were that it seemed thin. After putting it on and the wearing it outside in 18 degree temps with only a tee shirt underneath I was surprised at how warm I felt. This particular piece I will wear more for lifestyle things but so far I’m impressed. Very good quality and excellent fit and I also love the deep chest pocket. Sleeves are a bit long on me and if there is one negative at all I would say I wouldn’t mind having thumb holes in the sleeves. Great product!
