Ideal for mountaineering, alpine climbing, mountain walking or for any activity where warmth and breathability are paramount.
Alpha® technology looks set to revolutionise how synthetic insulation is used in the mountains.
||||Polartec Alpha, Overheating is Underperforming - So unlike traditional synthetic fill or down, Polartec Alpha allows a free exchange of air to keep you warm, comfortable and focused. Developed for U.S. Special Operations and now available for outdoor enthusiasts, it takes performance fabric—and you—to a totally new place. Click the Logo to read more...|

A matt finish to the fabric gives it fashion appeal but the real story is in Polartec Alpha itself, designed to be worn when you are active - so on the move - there are alternative insulation garments that are more suited to wearing around camp - Strata is about keeping you vented even though you are also being kept insulated.
Its quite a breakthrough, especially for cold weather walking when you need insulation but start sweating hard when you reach a strenuous bit. Weight for weight Polartec Alpha is only about half as warm as Primaloft so the king of insulation keeps its crown - but Alpha has its place - I recently wore an Alpha garment all day while walking in Corsica in particularly cold conditions and stayed warm & comfortable for the duration - I kept checking my baselayer, which stayed completely dry.
From a design point of view it has all the features you would expect to find on a quality product from RAB.
