Midweight Active Insulation Technology provides movement-mirroring stretch, resilient weather protection, and high breathability in this do-it-all midlayer.
Outdoor Research says:
For those days when it feels like summer one minute and ski season the next. If you’re tired of the constant quick-change game, the Ascendant Vest is for you. Breathable and wicking enough to leave on even when you’re trucking hard uphill, the Polartec Alpha Direct Insulation will still keep your core comfy when it’s time to rip your skins off in chilly ridge-top gusts. Perhaps the perfect spring skiing partner.

Some of you may have used, or at least read about Polartec Alpha insulation, a more modern version of a lightweight fleece, that keeps you warm but lets sweat out, even when active. Well the Polartec Alpha Direct insulation is basically the same but with the mesh liner removed, so you get more unimpeded airflow (not to mention less weight and bulk) without sacrificing warmth. It also feels super soft against your skin!
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 - Polartec Alpha Direct 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.
A water-resistant Pertex Microlight outer fabric repels light rain and snow, while still allowing sweat and heat out. Ideal as an outer layer in spring and fall or as a mid layer in winter.
