Thermlite 2.0 Socks
Merino wool inner
Lighter, stronger, and more comfortable – the waterproof socks Thermlite 2.0 keep your feet dry and warm through cold, wet conditions.
The updated 2.0 version features a lighter outer knit for reduced bulk, hidden terry-loop reinforcement at the heel and toe for better durability, and a finer-textured cuff that softens contact with the lower leg. With a Porelle® waterproof-breathable membrane and a thin Merino-wool lining, these socks balance reliable waterproof protection with natural warmth and comfort for everyday wear, hiking, or cycling in unpredictable weather.

The DexShell Thermlite 2.0 is built with our proven three-layer waterproof construction – upgraded for lighter weight and greater comfort. A durable outer knit resists abrasion while reducing bulk, and a Porelle® waterproof-breathable membrane blocks external moisture without trapping heat. Inside, a fine Merino-wool lining regulates temperature and manages odor naturally. Hidden terry-loop reinforcements at the heel and toe enhance durability and softness where it matters most.
Frequently Asked Questions
Q: Why do I need waterproof socks if I already have waterproof boots?
A: Boots can be heavy and slow to dry. Once water gets in from the top, your feet stay wet. Waterproof socks offer a lighter, more flexible solution for stream crossings or mixed-weather days.
Q: Are waterproof socks fully rain-proof?
A: Not entirely. They repel rain and mud, but extended exposure can allow water to enter from the top. Use with gaiters or waterproof trousers for maximum coverage.
Q: How breathable are they?
A: Our waterproof socks use a British-made Porelle membrane with 70% breathability, letting sweat escape while keeping water out.
Q: Why is it better to choose a size up?
A: The laminated waterproof construction has less stretch than ordinary socks. Size up if you have wide feet or are between sizes for a better fit.
Q: How should I wash them?
A: Machine wash cold with mild detergent and air-dry inside out. Avoid direct heat or high tumble settings to protect the membrane.
