Best Thru-Hiking Backpacks (2026)

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, with a $199 UltraGrid version and the $279 Ultra 200X build listed here. It has become the value benchmark every new UL pack gets measured against.

The Lightning is Exped's lightweight trekking pack and carries the most surprising spec on this site: a 48.5 lb load rating at 2.65 lb of pack weight. Its T-Rex carrying system uses an adjustable aluminium stay with reduced back contact for ventilation without giving up load control.

The Swift X is the laminate version of Six Moon Designs' Swift (X-Pac VX21 or LS21, or Ultra 200X), using the same Delrin hoop frame as the Swift V but in a waterproof laminate. At 38.8 oz it is heavier than most packs in this segment, which is the cost of the hoop and the fabric.

The Asher is Kelty's value backpacking pack. At $170 and 3 lb 2 oz it undercuts everything with comparable capacity, and reviewers consistently place it as the budget pick.

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 Eja is the women's-fit Exos and Osprey's lightweight trekking pack: 2.8 lb for 58 L, with the same AirSpeed suspended mesh as the Atmos in a stripped-down chassis. It is the pack that bridges mainstream and ultralight, offering a frame and ventilation at a weight that cottage packs compete with.

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.

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 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 Exos Pro is Osprey's answer to the cottage ultralight brands: 33.2 oz for 55 L, or 30.4 oz with the lid removed. It uses NanoFly, a 100D nylon crossed with 200D UHMWPE, over a 3.5 mm LightWire frame, and saves about three-quarters of a pound against the standard Exos 58 at the cost of load rating and a fixed hipbelt.

The Flash Air is REI's ultralight pack, using a shaped spring steel frame rather than stays or a hoop. It is the only pack in this group backed by a mainstream retailer's return policy, which matters more than usual in a segment dominated by made-to-order cottage brands.

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

The Maven is the women's-fit Paragon and the pack that most gear roundups name as the best all-round women's backpacking pack. At 3.4 lb it sits between the overbuilt Deva and the ultralight Facet, which is why it wins comparisons on balance rather than on any single number.

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 minimum weight of about 2 lbs.

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.
