The Arcteryx Proton Hoody 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 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 Coreloft Compact 80 air permeable insulation which provides very breathable warmth. The Proton is the ideal hiker or climbers jacket for when the valley bottom is hot but higher and more exposed terrain is much cooler. The Proton Hoody is breathable enough to be worn all day, but at just 400g (medium) its light enough to go in your pack for emergencies.
The Proton features and adjustable insulated hood that will go over a helmet. There are two zipped hand pockets and one zipped chest pocket. The Proton is Fitted Fit with articulated patterning for freedom of movement. This is an excellent climbers and hikers layer for those unpredictable spring and summer days.
