Backpacking

Designed specifically for backpacking

Which pack is right for you?

Choose Outro 40 if you:

  • Prefer a lighter, more compact pack that still handles multi-day trips with a dialed, organized layout.
  • Run a lighter kit, carry under roughly 30 lb, or mostly do 1–4 night trips where fast travel and comfort matter more than extra volume.
  • Want one pack that can handle everything from hut routes and loop weekends to minimalist thru sections.

Choose Outro 55 if you:

  • Need extra room for week-long trips, shoulder-season loads, bulkier sleep systems, or group gear.
  • Want the same organization and comfort as the 40, but with more headroom for food, layers, or camera equipment.
  • Prefer a pack that still feels balanced and supportive when loaded up for bigger objectives.
