Devold Expedition Merino Silk Zip is a technical wool base layer developed for extreme weather conditions. The garment consists of two layers: an inner layer in 100% soft merino wool and an outer layer with 90% aquaduct-treated merino wool. The aquaduct technology ensures efficient moisture transport by drawing moisture away from the skin and allowing it to evaporate quickly, keeping the body dry and comfortable.

In this updated version, 10% silk has been added to the outer layer, replacing polyamide. The silk provides increased durability, a luxurious feel against the skin and a more refined look, without compromising the natural properties of merino wool.

The top has very high insulating capacity and excellent moisture-wicking properties, making it ideal for the coldest days. The design includes double cuffs for improved shape retention, an extended back panel for extra protection, flat seams to prevent chafing, raglan sleeves for optimal freedom of movement, and pulse warmers with thumb holes.
