The Bergans Letto Jacket is very lightweight and provides reliable weather protection. Plus, it has an ergonomic fit! The jacket is made of the 3-layer Dermizax fabric. This tough, waterproof and windproof membrane is also very breathable. In addition, this waterproof jacket features a slightly extended back for added protection against the elements. The jacket is also equipped with a drawstring at the hem for easy adjustments. The articulated elbows with elasticated cuffs allow for increased freedom of movement whilst climbing. For ventilation, there are long underarm zip vents and a two-way zip in front. Of course, the jacket features a hood reinforced with wire, which can be adjusted and rolled away into the collar when you're not using it. The 2 front pockets are positioned somewhat higher so that you can still access them whilst wearing a climbing harness. Thee insides are made of mesh for additional breathability. For safety and visibility in the dark, the Bergans Letto Jacket also features a reflective logo.
