The perfect ultralight frameless pack for peak bagging, overnighters, and short trips, the Sub-Nero Ultra is a smaller and slightly more stripped down version of our popular Nero Ultra Backpack.

Streamlined to only the most essential features, the Sub-Nero Ultra is great for hikers with dialed in base weights and minimalist kits.

Featuring an included sit pad, an optional webbing belt, and a variety of optional modular add-ons, the highly versatile Sub-Nero Ultra allows you to get the most out of any day, section, or thru-hike.
