For real one-bag travel — a week of clothes, no wheels, straight past the check-in desk — the Osprey Farpoint 40 is the pick. It has a lifetime guarantee and a harness comfortable enough to actually walk in. Buying for a woman, or anyone with a shorter torso? The Osprey Fairview 40 is the same bag re-fitted, and for them it's the more comfortable choice.
One-bag carry-on vs. a travel daypack
Two very different bags both get called a "travel backpack," and picking the wrong category is the biggest mistake here. A 40L one-bag pack — the Farpoint, the Fairview, or the Cotopaxi Allpa — is a soft carry-on you wear on your back; it holds a week of clothes and replaces a suitcase entirely. A travel daypack — the MATEIN or KROSER — is a large, laptop-friendly bag meant to be your everyday-plus-trips personal item, the thing that slides under the seat in front of you. Decide which one the person actually needs before you look at anything else; it settles most of the decision.
Harness and fit — the part everyone ignores
A one-bag pack rides on your back fully loaded, so the harness matters far more than the color. Osprey's padded, ventilated harness is the reason the Farpoint is the pack the internet keeps recommending — it carries real weight without wrecking your shoulders on a long walk to the gate. Crucially, fit is about torso length, not gender: the Fairview is the Farpoint tuned for a shorter torso, which is why it's the better pick for many women — but a tall woman may be happier in the Farpoint, and a shorter man in the Fairview. The budget daypacks have simple straps and no real hip belt, which is fine for a personal item but gets tiring when they're stuffed full.
Clamshell vs. top-load
How the bag opens changes daily life more than a few liters of capacity ever will. A clamshell pack — the Farpoint, Fairview, and Allpa all qualify — unzips flat like a suitcase, so you see everything at once and pack it in neat layers instead of digging down a narrow tube. A top-loader makes you unpack to reach anything at the bottom. For travel, the clamshell wins every time; drop a set of packing cubes into one and living out of the bag for a week is genuinely painless.
When a wheeled bag beats a backpack
Here's the honest skip. A backpack's whole reason to exist is stairs, cobblestones, sand, and everywhere wheels can't roll. If your person glides their bag across airport tile and hotel lobbies and never hauls it anywhere rough, a travel backpack just parks the weight on their spine for no reason — a wheeled carry-on is the kinder gift. And don't buy a 40L one-bag pack for someone who only wanted a laptop daypack; it's more bag than they'll ever fill. Backpacks are perfect for the hiker or the traveler who moves under their own steam — less so for a pure pavement roller.
How to choose a travel backpack
One-bag pack or travel daypack?
Start here. If the goal is to travel out of a single bag for days at a time, you want a 40L-ish one-bag pack like the Farpoint, Fairview, or Allpa. If they mostly need a smart, roomy bag to carry a laptop and the trip essentials alongside a suitcase, a daypack like the MATEIN or KROSER is the right — and far cheaper — call.
Get the fit right (it's torso length, not gender)
The single biggest comfort factor is matching the harness to the person's back. The Fairview is built for a shorter torso and the Farpoint for a longer one; that, not the label, is what makes a loaded pack feel light or punishing. When in doubt, buy on torso length and the person's own reach, not on the "men's" or "women's" tag.
Favor a clamshell opening — and add packing cubes
A suitcase-style clamshell that lies flat makes packing and repacking easy, especially paired with packing cubes. It's the difference between an organized week and a daily dig. If a pack only opens from the top, expect more rummaging.
Mind the carry-on rules and capacity
Around 40L is the classic one-bag size because it holds a week yet still fits most domestic overhead-bin rules. But cabin-baggage limits are set by each airline, not by a single global standard, and budget carriers are strict — it's worth a glance at the specific airline's size and weight rules before a trip so the "carry-on" doesn't get gate-checked.
How we chose
Every ranking site in this category implies a test bench. We don't have one. We compile the published specs (real dimensions, weight, capacity, TSA and cabin-size compliance), do the arithmetic a gift buyer actually cares about, pull live prices so nothing is stale, and score each pick against a published rubric. The scores are judgments from documented research — not measurements we took. Where a fact came from a manufacturer or a retailer, we name and link them in Sources.
