Mountaineer - OTC
The 100% Merino wool interior provides excellent moisture control and comfort while the nylon exterior provides maximum durability and abrasion resistance.
Other critical features include:
- Berry Compliant.
- Fully cushioned foot and leg.
- Merino wool next to skin feels great and is naturally anti-microbial and flame resistant.
- Nylon reinforcement on the outside of the sock for increased durability.
- Heel Lock® provides heel security that limits the chances of a blister when combined with a properly fit boot.
- Dynamic Toe Cup® limits the amount of material in toe box to prevent bunching in a critical area of the foot.
- Knitted construction naturally moves the seam back from the sensitive toe area.
Material
Made with fine-gauge, suit-quality merino wool, our materials are blended to optimize odor resistance, durability, breathability, stretch, and moisture-wicking.

Finer Fabric, Better FIT.
Whole Foot Comfort begins with premium fabric. That’s why we ground our knits with a higher quality 18.5-23.5 micron ‘fine-gauge’ merino wool. The kind typically used in luxury formal wear. This gives FITS a distinctly different, and superbly soft, feel unlike any other performance sock. Because no other sock is made like FITS.
All Day Comfort Guaranteed

United StatesNot what I expected
I’m am struggling with duplication of a current product I have purchased from you. The mountaineer is way too big and goes over my knees. I am looking for tactical that goes OTC. Can a representative call to discuss in person over the phone? 401-255-8708 Joe Pelletier

Hi Joe, Thanks for the review! Based on your order history, I believe what you are looking for is the Tactical - Boot in size XL. A customer service rep will reach out to you within 24 hours in case you have any questions. Thanks!
United StatesSeriously warm heavyweights
Great for layering. Quality construction and materials. Excellent discount.
United States United StatesSaving for winter
Good fit. Not too thick so my hiking boots aren't too tight. socks fit tight enough to stay on my skinny legs with plenty of stretch left.
United States United StatesMountaineer over the calf socks
These socks are long. I wear a size 13 and they go over my knees. I fold them back to just below my knees. I always had problems with rubber boots rubbing my shins. Not now. These socks protect my shins. The wool wears well and is comfortable. Great socks. Not too thick but thick enough to protect my feet and shins. They stay up.
United StatesToo Tall
I have loved these in the past but these are just too tall. They have the same excellent thickness and construction, just too tall.
United StatesAmazing socks
