Hyperlite Mountain Gear

Junction 55L Backpack

What Our Gearhead® Experts Are Saying:

"I’ve used the Junction 55L on everything from long thru-hikes to quick alpine pushes. The woven Dyneema fabric is unbelievably tough for how light it feels, and I never worry about wet gear thanks to the waterproof construction. The redesigned pockets make stashing a water bottle or wet jacket easy, and the carry stays comfortable even when I’m pushing close to the 40-pound load limit."

When we’re heading deep into the mountains, we need a pack that can handle weather, weight, and miles without holding us back. The Hyperlite Mountain Gear Junction 55L Backpack is built from fully woven Dyneema 200-denier fabric, giving us the perfect balance of waterproof protection, abrasion resistance, and featherweight design. With its roll-top closure, seam sealing, and external daisy chains, this pack keeps our gear dry while offering endless options for attaching extra essentials.

Redesigned shoulder straps and a shaped back panel keep the fit secure and comfortable on long hauls, while dual-density foam in the hip belt and contoured aluminum stays distribute weight efficiently. Side pockets provide protected storage for water or quick-grab items, while the center mesh pocket makes it easy to stash wet gear for drying. With hydration compatibility, removable compression straps, and OTG-style accessory options, the Junction is as versatile as the routes we choose—whether we’re linking ridges, trekking across deserts, or shouldering weeks’ worth of supplies.
