The Lasting TNW is a lightweight merino wool trekking sock knit from 75% merino for natural thermoregulation, designed for summer hiking and warm-weather adventures where a heavy sock would overheat. At 3.53 oz with a breathable ankle zone, a cushioned foot bed, and an elastic arch band, it gives hikers and travelers the odor resistance and moisture control of merino in a cooler, low-bulk build.
Hand-picked by our gear specialists for warm-season use, the TNW proves merino is not just for winter. The high wool content manages sweat and stays fresh across long days, while the dual-knit construction ventilates where you need airflow and cushions where the foot takes impact, from mountain trails to city sightseeing.
Who are the TNW socks best for?
The TNW suits summer hikers, trekkers, and travelers who want the comfort of merino without the warmth of a thick winter sock. If you overheat in heavy wool but still want moisture control and odor resistance, this lightweight build is the answer. It doubles as an urban adventure sock for long days of walking and sightseeing in warm conditions.
What is the TNW sock made of?
The blend is 75% merino wool with polypropylene, polyamide, and Lycra for structure, moisture transport, and stretch. Merino handles thermoregulation and odor resistance naturally, while the dual-knit layout places breathable panels at the ankle and cushioning under the foot. An elastic arch band locks the sock to the midfoot, and reinforced heel and toe zones extend its lifespan.
How does the TNW compare to a winter merino sock?
Against a thick winter merino sock, the TNW keeps the wool benefits of warmth regulation and odor control but strips the bulk and heat for summer use. Against a synthetic running sock, the high merino content adds natural freshness and better temperature balance over long days. It sits in the warm-weather trekking niche rather than cold-season insulation.

Questions & answers
TNW FAQ
Are merino wool socks too warm for summer hiking?
Not this pair. The Lasting TNW is a lightweight merino sock rated for summer and warm weather, and merino naturally regulates temperature rather than only trapping heat. The breathable ankle knit adds airflow, so it stays comfortable on hot trails.
Do these socks help with odor?
Yes. Merino wool has natural antibacterial properties that resist the buildup of odor-causing bacteria, and at 75% merino this sock leans heavily on that benefit. It stays fresher than synthetic socks during extended and multi-day wear.
How much do the Lasting TNW socks weigh?
They weigh 3.53 oz, which is light for a merino trekking sock. The low weight and low-bulk knit fit comfortably inside trail shoes and lighter hiking boots without crowding the toe box.
What sizes are available?
The TNW comes in S, M, and XL. Choose the band that matches your usual shoe size so the elastic arch support band and cushioned zones line up correctly on the foot for the best fit and comfort.
