Osprey Farpoint 40 vs. Cotopaxi Allpa 35: the one-bag travel decision

One carries like a scaled-down backpacking pack, with a suspended frame moving weight onto your hips; the other opens flat like a suitcase and undercuts it by nearly a pound. We compared dimensions, frame construction, fabric weight and FAA/TSA carry-on guidance to find your one bag.

The short version

If you’re carrying this loaded for hours — train platforms, hostel stairs, a full day before check-in — buy the Osprey Farpoint 40. Its suspended internal frame and padded hipbelt move weight off your shoulders, which a frameless bag can’t match once fully loaded. Buy the Cotopaxi Allpa 35L instead for the lighter pack, a shell that holds up better in bad weather, and a bag that unzips completely flat for packing cubes.

Osprey Farpoint 40 Travel Pack

Best for carrying comfort

Built like a backpacking pack, with a frame to prove it

~$160–180

Check price

The Osprey Farpoint 40 is built like a scaled-down backpacking pack, not a suitcase with straps sewn on. Osprey’s LightWire frame moves the load onto a padded hipbelt, the system used in the brand’s trail packs. At 21.7 x 13.8 x 9.1 inches and 40 liters, it clears the roughly 22 x 14 x 9 inch sizer most U.S. airlines use, though the FAA notes rules are set by each airline.

Its shell is bluesign-approved recycled nylon — 210-denier on the main panel, 420-denier on the bottom — with a PFAS-free DWR coating, resisting a shower but not standing water. The laptop sleeve fits up to 16 inches, larger than most travel packs bother with. The harness zips away flush for gate-checking, and Osprey backs it with the All Mighty Guarantee: free repair for any damage, any reason, no receipt required.

At 3.3 pounds empty, the Farpoint 40 is nearly a full pound heavier than the Allpa 35L, the tradeoff for a real frame instead of foam padding. It opens from one side, making packing cubes slightly more fiddly than a true clamshell. Osprey’s own site lists it at $200, above typical street price. For anyone who’s finished a travel day with sore shoulders from a frameless bag, the extra weight buys real comfort.

Strengths

Suspended internal frame and padded hipbelt transfer weight off your shoulders
Laptop sleeve fits up to 16 inches, a size up from most travel packs
Harness, hipbelt and backpanel all zip away flat for gate-checking
Backed by Osprey’s All Mighty Guarantee: free repair for any damage, any reason, any era

Tradeoffs

Nearly a full pound heavier empty than the Cotopaxi Allpa 35L
Opens from one front panel rather than laying fully flat like a suitcase
Lighter 210-denier main fabric relies on a DWR coating rather than a taped or TPU-coated shell
The matching detachable daypack that completes the modular system is sold separately

Verdict

Get it if: you’re carrying it fully loaded for hours at a time — a train station, a hostel staircase — and want a real frame doing the work instead of padding alone.Skip it if: you’d rather have the lighter pack, or want a bag that opens completely flat like a suitcase for packing cubes.

Cotopaxi Allpa 35L Travel Pack

Best for packing light

Opens flat like a real suitcase, and weighs less doing it

~$180–200

Check price

The Cotopaxi Allpa 35L opens the way an actual suitcase does: a full wraparound zipper unzips three sides and the main compartment folds flat, instead of one front panel like most travel backpacks. At 22 x 12 x 10 inches and 35 liters, it clears the same rough 22 x 14 x 9 inch sizer as the Farpoint 40, though its 10-inch depth runs past what the TSA’s guidance describes as typical, so measure your airline first.

Cotopaxi builds the shell from 840-denier recycled nylon: a TPU-coated base plus a ballistic-ripstop layer with a PFAS-free DWR coating, heavier and more water-resistant than a DWR-only fabric. That shows up in bad weather — it sheds rain, snow and spills — and in the pass-through strap that slides over a rolling bag’s handle. The main compartment locks with anti-theft YKK zippers, plus a fleece-lined 15-inch laptop sleeve.

At 2 pounds 15 ounces empty, it undercuts the Farpoint 40 by nearly a full pound, partly because there’s no internal frame: the backpanel is padded foam, so weight rides more on your shoulders once loaded. The straps tuck away for checking it, and Cotopaxi’s Guaranteed for Good program backs it with a lifetime warranty and repairs. Cotopaxi’s own site lists it at $230, above its typical range elsewhere.

Strengths

Nearly a pound lighter empty than the Osprey Farpoint 40 despite similar volume
Suitcase-style full-wrap zipper opens completely flat for packing cubes
Heavier 840-denier TPU-coated shell sheds light rain, snow and spills better than a DWR-only fabric
Lockable, anti-theft YKK zippers on the main compartment

Tradeoffs

No internal frame, so a fully loaded 35 liters rides more on the shoulders on long carries
Laptop sleeve tops out at 15 inches, a size smaller than the Farpoint 40’s
Current retail price runs closer to $230 on cotopaxi.com, above typical street pricing elsewhere
Fewer external organization pockets than a pack built around backpacking-style access points

Verdict

Get it if: you want the lighter pack, a shell that handles weather better, and a bag that opens flat like a real suitcase for packing cubes.Skip it if: you’re loading it heavy for a long carry and want a real frame moving weight onto your hips instead of your shoulders.

Travel backpack FAQs

Are the Osprey Farpoint 40 and Cotopaxi Allpa 35L both carry-on compliant?

Both clear the roughly 22 x 14 x 9 inch sizer most U.S. domestic airlines use: the Farpoint 40 measures 21.7 x 13.8 x 9.1 inches and the Allpa 35L measures 22 x 12 x 10 inches. But airlines set their own carry-on rules rather than following one federal standard, and FAA and TSA size guidance is a general reference point, not a promise any specific airline will accept a bag at the gate. International and budget carriers often run tighter limits, so check your airline’s own page before flying with either.

Which one is more comfortable to carry for a full day?

The Osprey Farpoint 40, if you’re carrying it loaded rather than rolling it or shuttling it in a car. Its LightWire internal frame and padded hipbelt move weight onto your hips the way a backpacking pack does, which matters once you’ve packed close to 40 liters. The Cotopaxi Allpa 35L has no internal frame, just a padded foam backpanel, so a fully loaded pack rides more on your shoulders over a long carry, even though it’s nearly a pound lighter empty.

Which pack is more durable or weather-resistant?

The Cotopaxi Allpa 35L’s shell, a TPU-coated 840-denier recycled nylon with a second DWR-and-PU-backed layer, is built to shed light rain, snow and spills. The Osprey Farpoint 40 uses a lighter 210-denier main fabric, 420-denier on the bottom, with a PFAS-free DWR coating but no TPU layer, so it holds up fine day to day but is more likely to let a heavier downpour through. Neither pack is submersible or fully waterproof.

Can either bag be checked instead of carried on?

Yes, both are built for it. The Farpoint 40 zips its harness, hipbelt and backpanel flush against the pack so nothing snags on a baggage carousel or conveyor belt. The Allpa 35L tucks its shoulder straps and hipbelt away the same way, and its main compartment locks with anti-theft YKK zippers, which matters more once the bag leaves your hands at check-in.

What’s the real difference in how these two open?

The Farpoint 40 opens through one large front panel, similar to most backpacking-style travel packs, so it lays mostly flat but not completely. The Allpa 35L unzips on three sides in a full wraparound zipper and folds open like an actual suitcase, with the main compartment split into one large section plus a medium and small pocket. If you pack with cubes and like laying everything out at once, the Allpa’s opening is closer to a hard-sided suitcase.

Do either of these come with a real warranty?

Both do, and neither requires much to make a claim. Osprey’s All Mighty Guarantee repairs any damage or defect for any reason, free of charge, no matter how old the pack is or whether you still have a receipt. Cotopaxi’s Guaranteed for Good program covers a lifetime warranty and repairs on the Allpa line, plus an option to trade the bag in toward a future purchase once it’s finally worn out.
