all around go to sock
This isn't a heavy sock by any means but I love the fit and the fact i can wear it for multiple days and it doesn't get that epic crunchy / stinky sock feeling. I take two/three pairs of these everywhere due to the padding where its needed and thin/breathable where it should be. great sock

They say merino makes all the difference...
It's not just any merino, quality matters. Not all merino wool is created equal. This summer I participated in a Fly Fishing event that took us to backcountry waters all over Colorado. I had a new pair of the Mtn Athlete Triad socks, along with other merino brands. The difference between them was night and day. The First Lite Mtn Athlete Triad socks were comfortable, durable, better at managing moisture in my boots, and they remained significantly more comfortable by the end of a long day. After that experience, I replaced my old wool socks with First Lite merino wool socks before hunting season. Now after a full season of hunting on these socks, I'm totally sold. From elk in Montana, to pronghorn in Wyoming, to mule deer in Colorado and Texas, these are my new go-to hunting socks.

Best Socks I've Ever Worn
I've never been one to pay much attention to socks, until now! Wore these for my first horn hunting expedition of the year and my feet never felt better. Socks were comfy, fit well, and did a good job regulating the temperature within my boots. I'm now a believer!

I had my boots stretched and re-soled and forgot to reapply my Obenauf's so when I stepped out of my raft into the freezing river to head to my stand my feet was instantly soaked. I was pissed as my thought was "damn, I just wasted this entire trip and have to bail" ,I was wrong!!!! I took off my boots and dumped the water and wrung out my socks then put everything back on fast as it was only 24F at the time. My feet was toasty warm in no time and I was very happy and stayed and hunted all day-wet boots but warm feet thanks to these socks.

Warm and Dry
Socks were great on their own. Padding in all the right spots. No smell after several days. Dried quickly each night and ready to go in the morning.

Good socks that stay put
Worn them 3 times now and love them. They stay put and have reduced fatigue in my feet. Depending on the boots I'm wearing I've worn them with and without a liner sock. They've performed equally well. Will order more.

Great Sock
These socks are fantastic for a couple of reasons. They are tall enough to get over the calf muscle and stay up. This is important when wearing other layers of clothes because you won't have pull them up every time you stop. Another great feature is the lack of hot spots when wearing them. They are sturdy, but not bulky. They are warm when needed and don't get too hot. Cannot recommend them enough.

Love it, but not for those with huge calves
I have calves that others have joked that I need to feed, as large as others thighs. I wish these wouldn't be so tight, I think another size up would be needed.

Awesome socks
I have hunted 7 total days so far in my socks and I can say I over them,I've always used smart wool ski socks and the first lite socks hands down blow them away! The socks are comfy,and my feet did not get hot in warm weather though rely impressed!

Good sock, but...
As with all FL gear construction and feel are great, really want to use them... BUT, I ordered a Large and they are not large enough. The package the socks come in say L=9-12 but the website doesn't clarify sizing for socks, normally this isn't likely a problem for all you normal people, but I have Shideshow-Bob feet (sz16). needless to say my big feet are well beyond that size range. I tried them on, they fit OK but I'm pretty certain they'll prove too small and result in some blisters. I'll likely be returning them for more First Lite gear!

Overlooked piece of gear!
This sock is awesome! I picked these up on a sale thinking that I would give a good pair of socks a try. Glad I did that. I get really hot, sweaty feet. I have tried a lot of things to fight off blisters but these are the best. Feels like wearing a sock with a liner. Now I wear them all the time! Wish I would have tried sooner! Highly recommend them.

A must have for happy feet!
The Triad sock is extremely comfortable, durable and stays in place. I mainly use mine for hunting, long distance running and any cold weather wear. I have never had a blister, sore spot, fabric wear or odor after multiple days of use. Definitely the best socks I have used. I recommend these sock to everyone.

Great Socks
I have worn these socks days on end and haven't experienced any fall down or odor. I even wore them breaking in a new stiff boot and the padding helped reduce the blisters and soreness associated with new boots. I would recommend them to anyone.

Never leave home without them...literally
Purchased these last season and will never leave home without them again. Literally, I love these so much that I wear them to work sometimes (and I work in an office). Breathe very well and have the perfect fit...these have never stretched out or fallen down. The merino wool essentially makes these scent free in my opinion (though when you take them off in the tent at night before bed watch out! ha). Buy these now if you haven't already - no regrets.

Best all around sock ever
These things are just so comfortable its hard to take them off. I find myself making sure they get washed as soon as I can so I can wear them again. Even for just everyday wear. Love them. Need to get a few more pairs!!
- drummerREM on 12/23/2016
Socks were never something I thought too much about, until I tried these. I thought fatigued feet and cold toes were a norm. Not with a quality pair such as the Mountain Athletes. A lot of foot support comes from these socks. And the warmth and comfort from these will change your day. My feet were noticeably less tired, and my toes stayed warm through wet and below freezing temperatures. Took them off and put them in the sun in midday and they were dry in 15 minutes. I can’t believe I used to wear sub-par socks. Never again.

Best socks around
I hiked in these dudes three days for a total of 22 miles at 11000' and my feet never got so much as a hot spot. The old merino socks I used to wear would give me some solid blisters after just one day. Very very comfortable and they stay in place- no sagging

Underrated piece of gear...
These are the most comfortable pair of socks I have worn. Underwear and socks are an overlooked piece of gear for many hunters/hikers, but the designers at First Lite nailed it on the Triads! Super comfy and they don't break down after a hard day in the boots. Both the Triad and Compression socks seem to be holding up well, but the Triads remains my favorite...
- Nick K. on 8/20/2016
Worth it
Don't be phased by the price. These socks are great. I have worn them a lot with my snake boots to keep them from rubbing and they are awesome. The wool is great because they can keep your feet really warm and absorb the sweat when it gets hotter. These socks will have you wearing them days in a row. Super comfortable and worth it.

best socks so far
love these, wish I had more.
- lucian on 4/11/2016
Absolutely Incredible!
Extremely comfortable, and incredibly durable; I've pretty much lived in two pairs between August and mid-January, hunting, and running hunts, from the mountains of Colorado, to the hills of AZ, to the river bottoms of KS, and they are STILL in great shape! I've washed them countless times, and worn them for weeks at a time (alternating between the two pairs) without washing, and they still look almost new, and still stay up 95+% of the time. My feet don't stink, I've had zero hot-spots, and no noticeable thread-wear so far. WELL worth the money.
