BUFF just entered a new category, and the feet of runners and hikers are the beneficiaries
The brand best known for neckwear launches its first performance sock collection, with three fabric technologies across six styles
BUFF, the Spanish brand behind the original multifunctional neck gaiter that's become a fixture in trail running and outdoor sport, has just launched its first-ever performance sock collection.
After 30+ years building a reputation in headwear and neckwear (many of which we have personally used for many years), the brand has turned its attention to socks, and brought its three core fabric technologies with it.
The lineup covers six sock styles across three performance tiers, available now at buff.com.

Three fabrics, six styles
CoolNet (Crew | Quarter)
The running and warm-weather option. CoolNet uses HeiQ Smart Mint cooling technology alongside moisture-wicking fibres and mesh ventilation zones for breathability.
Arch compression provides stability, flat seams and lightweight cushioning round out a sock built specifically for moving fast in the heat.
DryFlx (Crew | Quarter)
The run/hike crossover option. DryFlx is BUFF's quick-drying, high-stretch performance fabric; typically used in their headwear for active aerobic efforts.
In sock form it adds targeted compression zones for stability, light cushioning to reduce blister risk, and fast moisture evacuation for high-output efforts on trail or road.
Merino Lightweight (Crew | Quarter)
The all-season option, built for longer days on trail where temperature regulation and odour resistance matter more than pure speed.
Merino wool naturally wicks moisture, resists odour, and adapts to temperature changes; making this the choice for hiking, backpacking, and multi-hour efforts where the weather may shift.
Why this move makes sense for BUFF
The brand has been synonymous with the neck gaiter since 1992. That's not a bad place to start from when entering footwear accessories: BUFF already has strong credibility in technical materials, outdoor performance contexts, and the trail running community specifically.
The technology transfer is logical too. CoolNet, DryFlx, and Merino Wool are all established BUFF fabric platforms that have been used in their headwear and neckwear for years. Applying them to socks isn't a stretch (excuse the pun), it's the same materials brief (moisture management, odour control, all-day comfort) applied to a different body part.
If you've worn a BUFF gaiter or headband during a trail race, you'll already have a sense of what CoolNet and DryFlx feel like in motion. The socks translate that directly.
We've covered BUFF extensively over the years; from the Buff Epic Trail race (where we also got a tour of the BUFF HQ in Barcelona!) in the Spanish Pyrenees to the Pack Run Cap in our best running hats guide, and the sock launch is a natural extension of what the brand does well.
Which one to pick
If you run in warm conditions and want a lightweight, breathable option for road or easy trail — CoolNet.
If you're running or hiking on technical terrain and want more support and quicker moisture evacuation — DryFlx.
If you're spending long days on trail, hiking in variable conditions, or you just want a more natural fibre with temperature regulation — Merino Lightweight.
The Crew vs Quarter choice comes down to personal preference and the shoes you're pairing them with; Crew for more coverage and warmth, Quarter for a lower profile.
