Osprey Atmos AG 65

OutdoorGearLab's Sam Schild said it feels like the pack is giving you a hug and called it the most supportive hipbelt he tested; Switchback and Better Trail both rated its Anti-Gravity suspension the most comfortable all-rounder.

REI Co-op Trailmade 60

Switchback called comfort decent for the price and good to about 40 lbs, while CleverHiker rated it average; the dense foam hipbelt works but lacks a premium suspension.

Osprey Atmos AG 65

Carries a 40-pound load comfortably on the tensioned peripheral frame, though OutdoorGearLab noted it loses some comfort above 40 lbs where dedicated haulers like the Baltoro take over.

REI Co-op Trailmade 60

The internal aluminum frame and load lifters handle a 35-pound multi-day load, which Switchback confirmed on real trips.

Floor+scale (lighter is better): 50 + ((4.63-4.63)/(4.63-1.94))*50 = 50. At 4 lb 10 oz it is the heaviest pack in this set, which sets the 50 baseline.

REI Co-op Trailmade 60

Floor+scale (lighter is better): 50 + ((4.63-3.31)/(4.63-1.94))*50 = 75. At 3 lb 5 oz it is mid-pack, lighter than the Osprey winners.

Built from 210D and 420HD recycled, Bluesign-approved nylon; testers reported no durability concerns across hundreds of trail miles.

REI Co-op Trailmade 60

OutdoorGearLab praised the durable recycled nylon and 400D base, though Switchback noted the budget hipbelt foam will pack out over time.

Eight pockets, Fit-on-the-Fly adjustable hipbelt and harness, a J-zip front panel for full access, and an included rain cover make it the most complete feature set among the winners.

REI Co-op Trailmade 60

Six pockets and a U-shaped zipper give full panel access, and it is the most size-inclusive pack tested, fitting up to a 52-inch waist.

Strengths & Weaknesses

Osprey Atmos AG 65

+ Strengths
  • OutdoorGearLab, Switchback Travel, and Better Trail all ranked it the #1 Best Overall pack
  • The Anti-Gravity suspended mesh back panel gives the best ventilation and load support in the test
  • Fit-on-the-Fly torso and hipbelt adjustment plus an included rain cover cover the details
Weaknesses
  • At 4 lb 10 oz it is the heaviest pack here, as OutdoorGearLab and CleverHiker both flagged
  • Comfort tails off above a 40-pound load, so dedicated heavy haulers carry better
  • At $370 it is more than double the price of our value pick
Key flaw: Weight is the honest tradeoff.

REI Co-op Trailmade 60

+ Strengths
  • Named Best Budget or Best Under $200 by OutdoorGearLab, Switchback, Better Trail, and CleverHiker
  • The most size-inclusive fit in the test, adjustable up to a 52-inch waist
  • Durable recycled nylon and a full-access U-zip at $189
Weaknesses
  • Switchback and CleverHiker both called the comfort only average versus pricier packs
  • The budget hipbelt foam packs out over time, softening support
  • GearJunkie noted it sits too close in price to lighter, better-finished packs
Key flaw: You feel the price in the finish.

The Verdict

Our Bottom Line

The Osprey Atmos AG 65 won because the three most rigorous side-by-side tests we read all put it first. OutdoorGearLab's Sam Schild ranked it the Best Overall after testing 13 packs across thousands of miles, Switchback Travel made it their top men's pick after hundreds of trail miles, and Better Trail crowned it Best Overall on the Continental Divide Trail. They agree on why: the Anti-Gravity suspended mesh back panel. It is a continuous trampoline of tensioned mesh that extends from your shoulders into the hipbelt, so the pack rides off your back with airflow the whole way down. Schild put it plainly, saying it feels like the pack is giving you a hug, and called it the most supportive hipbelt in his test. Around that suspension Osprey wraps the most complete kit here: eight pockets, Fit-on-the-Fly torso and hipbelt adjustment you can tune while wearing it, a J-zip for full front access, and an included rain cover. It is not the lightest pack and it is not a dedicated heavy hauler, but for the everyday job of carrying a 40-pound load comfortably for a weekend or a week, nothing else balances comfort, ventilation, and features as well.

Best for:

  • Buyers who value a lifetime warranty and want to buy once
VALUE
REI Co-op Trailmade 60
REI Co-op Trailmade 60 Pack front 3/4 view in teal

The REI Co-op Trailmade 60 won on value because it is the pack the experts keep naming when the budget is the constraint. OutdoorGearLab tagged it Best Under $200, Switchback called it the Best Budget men's pack, and Better Trail and CleverHiker both pointed first-time backpackers to it. At $189 it does the fundamentals well: an internal aluminum frame with load lifters carries a 35-pound multi-day load, the recycled nylon body is genuinely durable, and a U-shaped zipper opens the whole pack for easy loading. It is also the most size-inclusive pack anyone tested, adjusting up to a 52-inch waist, which matters because a budget pack that actually fits beats a fancier one that does not. It sits more than $100 below the next-cheapest framed pick here, and for a new backpacker that gap buys boots or a sleeping bag.

Best for:
  • First-time backpackers building a kit on a budget
  • Anyone who needs a wide, size-inclusive fit up to a 52-inch waist
  • Occasional hikers who carry 35 pounds or less
  • Shoppers who want to keep the pack under $200
