Compare two 40-liter travel packs by dimensions, carry features, laptop storage, fit information, and what to verify before relying on either as airline carry-on luggage.
Two bags can both be labeled 40 liters and still feel very different on a trip. The Osprey Farpoint 40 is built around travel-focused carry details, including a stowaway harness and hipbelt. The REI Co-op Ruckpack 40 Pack – Men’s adds a listed 15-inch laptop compartment, a rain cover, and two fit ranges. Your decision may come down to how you pack, whether you want to carry the bag on a trail as well as through an airport, and how its dimensions compare with your airline’s rules.
This comparison uses each brand’s current product listing. Neither pack has been packed or flown by ReviewClearly, and a 40-liter label does not guarantee airline acceptance.
Quick verdict
Consider the Farpoint 40 if a travel-first layout, stowaway straps, and its listed 21.7-inch height suit your trip. Consider the Ruckpack 40 if the laptop sleeve, included rain cover, and available size ranges better match your packing and fit needs. Before booking, check the airline’s current carry-on limits and compare them with your packed bag; policies vary by carrier, route, and ticket.

Farpoint 40: a travel-first carry system
Osprey lists the Farpoint 40 at 40 liters, 21.7 × 13.8 × 9.1 inches, and 3.27 pounds. Its page describes a LightWire frame, an adjustable harness and hipbelt that stow away, and a load range of 7–16 kg. That combination points toward someone who wants a framed carry when walking with a packed bag, then a cleaner exterior when the straps are tucked away for transit.
Osprey’s page says the pack is sized for domestic carry-on requirements, but airline limits differ and can change. A product statement cannot guarantee acceptance on every flight, especially when the pack is full or its shape bulges. The checked listing showed the one-size version as out of stock; availability can change, so confirm before planning around it.
Ruckpack 40: more fit and travel details on the page
REI lists its men’s Ruckpack 40 at 40 liters, 23 × 15 × 9.5 inches, and 2 pounds 13 ounces. The listing specifies a sleeve for a 15-inch laptop or hydration reservoir, a full-zip design, a stowaway strap cover, and an included rain cover. It also lists XS–XL and XXL–4XL sizes, with the larger option using extended straps and hipbelt dimensions.
That information may help if you want one bag to move between travel and light backpacking or if fit options are important. The listed dimensions are larger than the Farpoint’s, so verify your carrier’s maximum size before treating either one as a cabin bag. REI’s current listing showed limited size/color availability when checked; confirm live stock and return terms.
Carry-on size is a trip-specific check
Do not rely on “carry-on compatible” as a universal promise. Airlines can have different size limits, and some weigh or measure carry-ons. Compare the carrier’s current published dimensions against the bag you intend to bring, including handles, compressed shape, and anything attached to the outside. A soft-sided pack can expand when filled, which makes a home measurement useful.
Also test the fit with a realistic load. If possible, adjust the torso straps, hipbelt, and sternum strap with weight inside. Read size guidance carefully; the Ruckpack’s two size groups and the Farpoint’s one-size listing are not equivalent fit systems.
Which should you shortlist?
- Shortlist the Osprey Farpoint 40 if a travel-focused framed carry and stowaway harness suit your packing plan, and its dimensions meet your airline’s current rules.
- Shortlist the REI Ruckpack 40 if a 15-inch laptop sleeve, included rain cover, full-zip organization, and published fit choices matter to you. Check dimensions and live availability.
- Wait to choose if you have not compared the bag against your airline’s allowance or tried the harness loaded. Comfort, packing access, and cabin acceptance cannot be settled by liters alone.
These packs share capacity but not the same profile. Osprey’s listed dimensions are smaller and its page centers the stowaway travel harness; REI lists a laptop sleeve, rain cover, and broader size ranges. Let your airline, actual load, and fit determine which to try first.
