DEVOLD MENS EXPEDITION MERINO 235 LONG JOHNS

Devold Mens Expedition Merino 235 Long Johns

The Devold Mens Expedition Merino 235 Long Johns deliver a flawless blend of high-performance technical engineering and sophisticated extreme-cold protection to your winter and alpine wardrobe. Meticulously engineered for severe arctic and mountaineering conditions, these heavyweight thermal leggings feature a dual-layer interlock knit structure that yields a substantial 235g/m² fabric weight. The inner layer is composed of 100% pure merino wool to provide a soft, itch-free texture directly against the skin, while the outer layer combines 90% Aquaduct-treated merino wool with 10% resilient polyamide for enhanced durability. This specialized Aquaduct treatment acts as an advanced moisture-transport system, actively drawing perspiration away from the body and transferring it to the outer surface where it rapidly evaporates, keeping your skin dry and warm during intense physical exertion.

Optimized for prolonged exposure in freezing environments, the dense merino fibers leverage natural crimp structures to trap massive pockets of insulating air, providing an exceptional warmth-to-weight ratio that continues to perform even when damp. The technical construction features a wide, ergonomic elastic waistband that ensures a comfortable, low-profile fit beneath heavy ski pants, while a functional fly adds practical utility. Built with an anatomically articulated design to mirror your lower body's natural movement, these long johns employ friction-free flatlock seams to entirely eliminate skin chafing and pressure points under pack straps or harnesses. Thanks to the natural odor-resistant properties of merino wool and Devold's machine-washable Total Easy Care treatment, this technical base layer remains fresh across multi-day expeditions and stands up to rigorous seasonal wear.
