Unisex Teflon 3-Proof Softshell Trek Pants

The pants use a 3-layer composite built around a Teflon fabric protector. The outer Teflon coating creates a nano molecular barrier that repels water, oil and stains, while the middle TPU membrane blocks wind and rain. Together they shed rain, snow and splashes to keep you dry in damp conditions — the "3-proof" protection the pants are named for.

Yes. The Frontlong softshell trek pants are a unisex men's and women's style with a regular straight-leg fit. An elastic waist with an adjustable drawcord and elastic-cord cuffs let anyone fine-tune the fit, so you simply choose your size from the chart rather than a gender-specific version.

Four versions cover every season: the spring/autumn 3-proof no-liner for mild weather, the fleece 3-in-1 for cold days, the down 3-in-1 with a 90 white duck down liner for the coldest conditions, and the summer ice-cool version (90% nylon, 10% spandex) for hot-weather breathability.

Measure your waist, hip and height and compare them with the cm size chart on this page. The spring version runs S–4XL, while the extended range covers S–8XL for larger body types. If you fall between sizes, the adjustable drawcord waist and cuffs provide extra room.

Yes. The winter 3-in-1 versions pair the softshell outer pants with a detachable liner — either warm fleece or 90 white duck down. Wear the shell alone in mild weather or attach the liner for insulation, giving you multiple configurations from a single pair.

Yes. The middle TPU membrane is waterproof yet highly moisture-permeable, letting sweat vapor escape during hiking, trekking or climbing while blocking rain and wind. The soft skin-friendly inner layer adds comfort, so you stay dry from both outside moisture and perspiration.

Gently hand-wash in clean water or wipe with a soft damp cloth — do not scrub or rub locally. Fabric softeners, laundry powder and liquid detergent can reduce the 3-proof performance. Note that the Teflon coating is not permanent and its effectiveness gradually decreases after about five washes.
