Snowbee Nivalis Down Jacket
Our new Nivalis Down Jacket is without doubt, the most technical garment we have ever made!
For many years, mountaineers and polar explorers have relied on the unparalleled lightweight insulation properties of natural feather down to keep them warm in extreme conditions. The problem, however, is that down loses most of its thermal properties as soon as it gets wet. Many manufacturers have tried to avoid this by either treating the outer shell with a DWR fi nish, or using feather down with a hydrophobic treatment to repel water and prevent clumping. Both methods have their limitations... so we thought why not put the down in totally waterproof pocket to protect it? Problem solved!
Nivalis Down Jacket Our new high-tech Nivalis Down jacket features a totally unique construction technique - an internal and external 3-layer laminated fabric, using hidden, internal stitching to form the down pockets. This means there is no external stitch-line to allow water to penetrate. The down pockets are formed using 2 layers of double-knitted Tricot and then protected, inside and out, with a TPU waterproof membrane, so the down remains 100% dry. The outer shell is a woven micro-fi bre polyester fabric with DWR treatment, so rain-drops run off the surface. Inside, there is a superlight woven polyester lining, with peach-skin fi nish, for comfort. The natural down fi lling contains 90% duck-down, 10% feathers and uses a fill power of 700 for total warmth, while the waterproof membrane has a hydrostatic pressure resistance (waterproofness) of 5,000mm to keep you dry and also provides total wind resistance. The main front zip and the two side hand-warmer pockets use waterproof zips and there is a fully adjustable, 3-panel hood made in the same insulated material as the body. Inside the jacket there are two deep pouch pockets at the bottom, for mobiles, wallets etc.
