I previously only used poly pros issued by the military as my base layers but decided to try First Lite. I initially purchased the Fuse top & bottom as a next to skin base layer. The first time I used them temps ranged from 15-50 degrees. I wore underneath regular blue jeans and a hoody when scouting early season in Wisconsin & Maine and was generally comfortable. I actually forgot I even had them on most times because they're so comfortable. If paired with the right insulating layer and/or windstop jacket, you could treestand hunt. Might have to step up to the heavier base layer if expecting temps to reach single digits though. Actually looking at buying my dad a pair for general wear during Maine winters. They are so great at wicking I had no issues with sweating and getting cold. I also slept in these, as I typically only shower once or twice during my week long hunts in Wisconsin. These things 100% keep the stink off of you! Their merino wool is legit! Sizing feels great for me but guys with a shorter wingspan might feel as though the sleeves are a tad bit long. I also own competitor base layers and actually prefer those from First Lite. I plan to test out more pieces from First Lite and have pretty high expectations based on my initial experience with their base layers.
These things fit perfect and are a great layer!
I purchased this piece last year and wore it as a mid archery season base layer (paired with the obsidian merino pant) when the morning temperatures ranged from 45-50. It will certainly be in my bag this Sept. when I go on my first back country elk hunt, and trust it will serve me well there as well. Everything I have purchased from First Lite has been of exceptional quality and has no doubt made me more efficient in the field.
Wore this as a base layer on a 4 day backpacking trip in the mountains of western Wyoming in April. Temps ranged from 20-50. It kept me warm in the mornings and dry in the afternoons.
They fit great and are very soft with good stretch. It's amazing how fine the fibers are on these. Throw them on under your pants of choice and you won't regret it. They keep you comfortable in the early morning chill and aren't to hot when the temp rises throughout the day. So much warmer, cooler, stretchier, and breathable than Walmart and Academy base layers. If you can only afford 2 pieces of First Lite gear then get these and the top to start out.
I’ve been wearing these for over a year and they do not disappoint! Great in transitional weather. They keep down odor especially well on Multi-day backpack hunts. I would t wear any other pair out in the field.
Like all of my FirstLite gear, I wear these all the time!!
Excellent performance, both breathable yet warm, and super comfortable. I love the versatility of these as well, I've used them equally as base layers for backpacking trips, treestand hunting, and underneath my neoprene waders for duck hunting. Just buy them already!
I have been wearing these almost daily this winter and they have not disappointed. They have traveled with me on glacier hikes, shoveling snow, outdoor work and daily wear around town. In temperatures from 30 degrees F to -17 degrees F they have warded off the cold. I usually wear these under a pair of cargo pants or under my uniform for work. They are comfortable and I forget that I am wearing them fairly often. Unlike other thermals I have worn these do a good job at adjusting to warmer temperatures when you get indoors out of the cold. They can still get toasty indoors, but less so than other brands I have tried. If you are working in -5 degrees F or lower you might want to look at a pair of firstlite’s thicker thermal offerings in my opinion. These have worked great for me and I have no regrets with my purchase. They fit comfortably and don’t tent to fall down through the day. They have also held up well through multiple trips through the washing machine. buy with confidence.
