What Our Gearhead® Experts Are Saying:
"I use this pack when I want to strip things down and move efficiently in the mountains. The modular volume is genuinely useful, not gimmicky, and the carry stays stable even when it’s packed light. It’s one of those packs that disappears on your back once you start moving."
When the objective demands speed, precision, and adaptability, we trust the TRILOGY JORASSES 20+5L Backpack to keep pace. Built by Millet for fast-and-light mountaineering, this pack adapts to the route ahead, whether we’re pushing for a minimalist summit bid or adding capacity for longer, gear-heavy days.
At its core, the pack offers a streamlined 20-liter configuration that stays light and agile, with the option to add a removable 5-liter extension when extra layers, hardware, or food are required. Ergonomic, ventilated shoulder straps keep the carry comfortable during sustained movement, while the removable waist belt and sternum strap let us fine-tune the fit or strip weight when efficiency matters most. Reinforced ripstop construction stands up to abrasive rock and sharp tools, and thoughtful details like ice axe holders, rope carry, and gear loops keep critical equipment accessible without slowing us down.
