Shell Day trip: Blend lightweight breathability with protection. Rab’s Fusion (1 lb. 1 oz.) uses Polartec’s NeoShell where rain hits, and a no-membrane poly where you sweat. Multiday: You may never need to wear it, so prioritize packability. Patagonia’s Super Pluma is low-bulk, lightweight, and has pack-friendly pit-zips and pockets.
Cold Temperatures (<30°F)
Baselayer Day trip and multiday: Try a midweight layer with enhanced insulation, like Columbia’s Omni-Heat Half-Zip. It will provide sufficient warmth with just a shell, but you can layer it without bulk.
Pack Day trip:Pieps’s Plecotus has an exterior avy-gear pocket and 36-liters of interior space— perfect for cold- weather gear. Multiday: Large capacity, adjustable fit, and lightweight, rigid support are keys to hauling big winter loads. Try GoLite’s Terrono 90.
Shell Day trip and multiday: Pack a heavy-duty weatherproof outerlayer like Mammut’s Eiger Extreme Nordwand. Pair it with just your baselayer, or your insulating puffy for versatility at camp and on the slope.
