Nalehko Alpha Underpants

Product detailed description

Nalehko Alpha underpants are basically miracle sweatpants. Lightweight, warm, and incredibly comfortable to wear – made from Polartec® Alpha 60 gsm, the same material we use for our popular Nalehko Alpha Hoody.

Polartec® Alpha was originally developed for US special forces, who required insulation that would keep them warm during activities, wick away moisture, and handle the transition between movement and rest phase perfectly. The result is a material with exceptional breathability, lightness, and thermal adaptability—it warms you when you need it and "breathes" to keep your body from overheating.

Nalehko Alpha Underpants feel like a second skin – they warm you up instantly, yet are light as a feather. Ideal as underwear under pants in colder conditions, but also as a warm layer in a sleeping bag when temperatures drop. Thanks to their unique properties, they have a wide range of uses, making them a great all-rounder.

Ergonomic cut, elastic waistband, and low-profile flat seams ensure maximum comfort and freedom of movement. No unnecessary details, no extra features—just pure functionality and comfort.

Washing instructions: Wash cold on a cycle for delicate clothes.

We recommend to use:  Nikwax - Basewash
