Description
Description
The Arcteryx Women's Proton Lightweight Vest is a super light insulating mid or outer layer designed for spring and summer conditions when you may need a little extra warmth. The Proton Lightweight Vest is made from 20 denier Fortius Air 20 outer which is impressively durable for its low weight. Fortius Air 20 balances air permeability for breathability when you are working hard, with light wind resistance. The insulation is a light layer of Octa Loft knit insulation which provides very breathable warmth. The Proton Vest is a great extra layer to provide extra core warmth. Wear it over a baselayer to keep the chill off or over a fleece layer to stop cold winds chilling your core.
The Proton Vest features two zipped hand pockets and one zipped chest pocket. The Proton Vest is trim fit making it an ideal layer for climbers and hikers who don't want lots of extra fabric flapping around and getting caught.
