The Arcteryx Proton LT Hoody is our highest rated all-purpose active insulation jacket. It performs well at a wide range of activities and has durable fabrics and insulation. It is a versatile workhorse! We used the Proton LT Hoody more than any other jacket during our two-year test period. It excels at active pursuits in cold weather and it performs well for three-season activities if you also carry a windshell or hardshell. Overall, we highly recommend this jacket if increased versatility and durability are more important than either low weight for stationary uses or exceptional breathability for the highest exertion activities in cold weather.
If you want less warmth and increased breathability for the highest exertion activities in cold weather, consider the Patagonia Nano Air Light. If you want the highest warmth to weight ratio for mostly stationary use, consider the Nunatak Skaha Apex.

A comprehensive Synthetic Insulated Jacket State of the Market Report will be released on March 25, 2018. When that report is published, we’ll update this review with a comparison summary of this product with other notable products in the review.
Many marketing claims from outdoor manufacturers are wildly inaccurate or inflate a product’s performance. Arcteryx’s primary marking claim is “obsessive design.” The author ground-truthed this while touring their North Vancouver design studio and factory in 2013. We have also found that the Proton LT Hoody holds up to their claim. This jacket is exceptionally well designed and built.
