The Lasting CXS is a lightweight trekking sock for warm-weather hiking and travel, built with X-Static silver fiber for lasting odor control and a ventilated instep for airflow in a rated +15C to +30C temperature range. At about 2.82 ounces it is a thin, breathable layer aimed at hot-weather comfort rather than insulation.
Hand-picked by our gear specialists as a summer outdoor clothing pick, this sock tackles the two problems of warm-weather trekking: sweat and odor. Permanent silver-yarn zones fight bacteria in the areas that need it most, while a stretch Lycra fit keeps the sock locked in place across long days of walking.
Who are Lasting CXS socks made for?
The CXS is for warm-weather hikers, trekkers, and travelers who want cool, fresh feet in the heat. If your feet run hot or you dislike the smell that builds up on multi-day trips, the permanent silver treatment is the standout feature. Sizes span S (34-37) through XL (46-49), covering a wide range of feet for summer hiking, sightseeing, and everyday warm-season wear.
How do Lasting CXS socks perform on hot treks?
On a hot trek, the ventilated instep mesh moves air across the top of the foot while the X-Static silver zones keep bacteria and odor in check even on back-to-back days. The Lycra fit holds the sock against the arch and heel so it will not slip or wrinkle inside your shoe, and the cotton-rich blend stays soft against the skin over hours of walking in the sun.
What is the fabric blend in Lasting CXS socks?
The blend is 75 percent cotton for a soft, breathable feel, 13 percent polyamide for durability, 7 percent Lycra for stretch and hold, and 5 percent X-Static silver fiber for its permanent antimicrobial performance. Being membrane-free and warm-weather rated, this sock is designed to keep feet cool and fresh in heat rather than to insulate, which defines its ideal use.

Questions & answers
Lasting CXS socks FAQ
Are Lasting CXS socks good for hot weather?
Yes, the CXS is rated for +15C to +30C and built for warm-weather hiking and travel. Its ventilated instep mesh, lightweight 2.82-ounce build, and breathable cotton-rich blend work together to keep feet cool and comfortable in genuinely hot conditions.
How does the silver fiber help?
The X-Static silver fiber provides permanent antimicrobial action that controls odor-causing bacteria and does not wash out over time. Reinforced silver zones in the foot, heel, and toe target the areas most prone to odor, keeping feet fresher across long or multi-day trips.
Do these socks stay in place while hiking?
Yes. A 7 percent Lycra content gives the sock elastic stretch that secures it around the arch and heel. This keeps the sock from slipping down or bunching up inside your shoe, which matters over the long periods of movement typical of a full day on trail.
What sizes do the CXS socks come in?
They are available in four sizes: S for EU 34-37, M for 38-41, L for 42-45, and XL for 46-49. Selecting the band that matches your shoe size ensures the ventilated and silver-reinforced zones align correctly with your foot.
