The Mariposa 60 backpack is Gossamer Gear’s bestseller. Here are my thoughts and first impressions. With a 35-pound weight and 60-liter capacity, it passes the bar for winter backpacking. It has a removable internal frame, 7 pockets, a comfortable hip-belt and shoulder straps, and weighs only around 2 pounds. You have a choice between small, medium, and large and you can configure the hip belt size as needed.
In my ongoing quest to find the best ultra-light backpack for winter backpacking, I recently tried Outdoor Vitals’ Shadowlight™ Ultralight Backpack. This is my first impression.
Most ultralight packs are designed for light loads and 3-season thru-hikers. In recent years larger size ultra-light packs have become available. The challenge is finding ones that are adaptable to winter backpacking requirements, such as a 30–35 pound weight limit, 50–60 liters of capacity, and the ability to put all liquids, a closed-cell pad, an ice ax, and snowshoes on the exterior. The Shadowlight Ultralight Backpack is one such option.
One of the best ways to lower the amount of weight you are carrying in winter is to get an ultralight backpack. Years ago when I set out to find a light winter backpack, I settled on the Granite Gear Leopard A.C. 58. Up until now, it was my gold standard. It was built with Granite Gear’s award-winning “AC” (AirCurrent) suspension, made with durable 100- and 210-denier high-tenacity Cordura nylon, and has a 58 liter/40-lb. capacity. At around 3 pounds (lid removed) it allowed me to keep my total winter pack weight at around 28 pounds, or 32 pounds with snowshoes attached (both base weight + consumables). It worked so well that when my pack began to show signs of wear, I resisted the newer Granite Gear packs and instead picked up a second-hand Leopard that I kept around as a backup.
