Hyperlite Mountain Gear

Junction 40L Backpack

What Our Gearhead® Experts Are Saying:

"I reach for the Junction 40L when I want a pack that’s light but still durable enough for tough miles. The size is perfect for weekend trips or section hikes with frequent resupply, and the mix of mesh and solid pockets makes it easy to organize gear. Even when I’m pushing the 40-pound limit, the frame and hip belt keep the load surprisingly comfortable."

Compact yet capable, the Hyperlite Mountain Gear Junction 40L Backpack is designed for fast-moving adventures where efficiency is everything. Built with Dyneema Composite Fabrics, the Junction balances ultralight construction with the rugged durability needed for rocky trails, changing climates, and long miles. Seam-taped panels and a roll-top closure keep the elements at bay, while external daisy chains and compression straps stabilize loads and expand carrying options.

The Junction’s design thrives on versatility—mesh front storage dries out wet layers, while the solid side pockets protect water bottles and essentials. Contoured aluminum stays, a padded hip belt, and foam back panel keep the carry balanced and comfortable even under heavy loads. Whether we’re linking desert trails between water caches or exploring alpine passes, this pack is the sweet spot between streamlined and expedition-ready.
