Best Thru-Hiking Backpacks (2026)

The Circuit is the thru-hiking pack — hand-made in Logan, Utah by ULA Equipment and a perennial #1 in Halfway Anywhere's PCT gear survey. Its 68 liters of total volume, bombproof Robic fabric, and 35 lb carry make it the default recommendation for first thru-hikes. An Ultra-fabric version is sold at a premium.

The Kakwa 55 is Dan Durston's disruptively priced ultralight — under 2 lbs, a 45 lb load rating, and a 2026 update with a redesigned hipbelt, all starting around $200 in UltraGrid fabric. It has become the value benchmark every new UL pack gets measured against.

The Crown3 60 is the third generation of Granite Gear's beloved Crown line, a fixture of PCT gear surveys and the classic answer to 'ultralight on a budget.' The re-flow hipbelt is adjustable in length, and the frame sheet and lid strip out for a sub-2-lb minimum weight.

The Southwest 55 is Hyperlite Mountain Gear's flagship all-rounder, built in Maine from waterproof Dyneema composite with solid woven pockets for brush country. It's the pack that made white Dyneema the visual signature of modern thru-hiking.

The Mariposa 60 is Gossamer Gear's signature pack, famous for its asymmetric pocket layout — one giant over-the-shoulder pocket that holds a tent, plus six more — and a removable back pad that doubles as a camp sit pad. It's the organized person's ultralight.

The Exos 58 is Osprey's crossover ultralight — a sub-3-pound pack that keeps a real suspended-mesh frame and lifetime warranty. It has been an Appalachian Trail staple for a decade, and the current generation added an adjustable torso. The women's version is the Eja 58.

The Focal 58 is Gregory's answer to the Exos: an ultralight with a genuinely ventilated FreeFloat suspended mesh back and a dynamic pivoting hipbelt. The women's version is the Facet 55. It undercuts the Exos on features while matching it on weight.

The Arc Haul Ultra 60 is Zpacks' engineering statement: a 21.7-ounce pack whose carbon arc frame tensions a mesh panel off your back — the only true ventilation in the sub-1.5-lb class. Backpacker magazine named it the best ultralight pack of 2026.

The Gorilla 50 is the Mariposa's smaller, symmetric sibling — 50 liters, under 2 lbs, and the classic 'second pack' people buy once their kit shrinks. It keeps the sit-pad back panel and Robic durability in a cleaner silhouette.

The Rook 65 is Osprey's budget-line backpacking pack, delivering a suspended-mesh AirSpeed back panel, adjustable torso, and included raincover for barely half the price of an Atmos. The women's equivalent is the Renn 65.

The Flash 55 is REI's ultralight value play — a roll-top pack with the co-op's Packmod system of removable pockets and straps, letting owners configure or strip it per trip. It's the cheapest credible ultralight framed pack from a major retailer.

The Trailmade 60 is REI's entry-level backpacking pack, built around inclusive sizing and a fully adjustable fit at a beginner-friendly price. A huge U-shaped front opening makes it one of the easiest packs to load and unload on the market.
