Triad 2.0 OTC Sock

Merino-Nylon Blend


In Stock & Ready to Ship

The evolution of First Lite’s best-selling Mountain Athlete Triad sock, the Triad 2.0 has been designed with all pivotal details in mind. Mapped Knit construction provides ankle and calf compression to keep your sock in place when hiking. While the padded footbed and ventilation zone on the lower keep you going for the extra miles. Finally, the seamless three-layer construction of the knit maintains continuous comfort by wicking moisture, managing odor, and thermoregulating for long seasons of use.

Triad 2.0

I learned about the First Lite Product Line through Expert Voice. I love outdoor activities and ordered a pair of the Triad 2.0 Socks, SM/MD in Charcoal Heather.
The socks are extremely comfortable, fit well, and a pleasure to wear. The Triad 2.0 kept my feet dry all day long. The socks provided excellent cushioning and padding for the soles of my feet..
They are well worth the price. I will be ordering more products from first lite. I have no problem recommending these socks to anyone.

One pair for 3 days

I love merino socks, in fact I collect them. I’m always looking at new brands and trying them out to see how they preform. I decided to try these socks for a backcountry mule deer hunt and they preformed great. I wore them for three days straight and put over 10 miles and several thousand feet of elevation gain and loss on them.

Triad 2.0 OTC sock

Perfect fitting favorite sock for all around comfort in many temp ranges. Worn on mule deer hunt with abnormally high temps in New Mexico. The moisture wicking abilities were terrific and kept my feet in good shape. Worn in sub 40 temps wading on a fishing trip, kept me as warm as I needed to be. Worn working cows early October in rainy muddy conditions with boots full of water and kept my feet in good shape. Best sock I’ve ever owned.
