Description
The traveler this Allpa 35L is built for
The Cotopaxi Allpa 35L is a travel backpack rather than a hiking pack, and the distinction runs through everything about it. It opens with a full wrap zipper like a suitcase rather than through a top lid, it has a 15 inch padded laptop sleeve, and the shoulder straps and hip belt tuck away when you do not want them. That is a bag for the traveler who moves between airports, buses and stairs and has decided to carry the load rather than roll it.
The trip is up to a week if you pack light, or a long weekend comfortably. Thirty five liters is genuinely one bag travel territory. The buyer who should not be here is the one who wants to roll: a backpack puts every pound on your spine and shoulders, and the cases in our carry-on luggage section put it on the floor. That choice is about your back, not about the bag.
Dimensions, and what a compressible bag does at a sizer
The specification block gives 12 by 10 by 22 inches. Set against the size guideline most often cited for United States domestic cabin baggage, roughly 22 by 14 by 9 inches, the pack is at the height limit, comfortably inside on width and an inch over on depth.
The depth figure behaves differently on a backpack
A rigid suitcase measured at 10 inches deep is 10 inches deep at the sizer and does not go into a 9 inch slot. A soft backpack measured at 10 inches deep when packed full will compress into a 9 inch slot if you push it, and will measure less than 10 inches when packed lightly. That is a real and useful property of the format, and it is why backpacks clear cabin allowances that rigid cases of the same stated volume do not.
It is not a guarantee. Packed to 35 liters with hard objects inside, the pack does not compress. We will not write that this bag is airline approved and Cotopaxi does not claim it. Check the allowance published by the carrier and fare you booked, note that budget and regional carriers are frequently stricter than the majors and that many international carriers weigh cabin baggage as well, and be aware that some carriers apply personal item rules to backpacks and carry on rules to others depending on how full they look.
Nothing on the listing states whether the published dimensions are measured empty, packed, or with the shoulder straps stowed. Straps and a hip belt that tuck away are exactly the components that add depth when they are not tucked. Tuck them before you approach a gate.
Fabric, construction and the opening
Cotopaxi states the pack is made with 100 percent recycled fabrics and describes them as more durable than the previous generation. What the listing does not give is a fabric name or a denier rating, which are the two figures that would let you judge abrasion resistance. Recycled content is an environmental statement rather than a durability one, and the two are independent. Ask for the denier before ordering if the pack will be thrown into bus holds.
The suitcase style full wrap zipper is the defining feature and it is worth explaining why it matters. A top loading pack forces you to dig, which means unpacking half the bag to reach the bottom. A full wrap opening lets the pack lie flat and open like a clamshell, so you see everything at once and can pack in layers or cubes. The internal pocket configuration is one large, one medium and one small compartment, which gives structure to that flat opening rather than leaving a single cavity.
The carry system is a genuine travel pack design rather than a daypack with a hip strap bolted on. Cotopaxi describes air mesh shoulder straps, ergonomic shaping, and a design that transfers weight to the hip belt. That last point is the one that determines whether 35 liters is pleasant or punishing: a pack that loads the shoulders is tiring within twenty minutes, and a pack that loads the hips is not. There are three grab handles, at the side, top and bottom, which is what you want when the bag comes off a conveyor or out of an overhead bin.
The laptop sleeve is padded, fleece lined and rated to 15 inches, which is one inch smaller than several competing packs. Check your machine. The listing does not say whether the sleeve is suspended off the base of the pack, which is the detail that decides whether setting the bag down transmits an impact into the laptop.
Other useful details: a stretch mesh water bottle pocket rated to one liter, a front zip accessory pocket with internal organization and a key clip, four exterior webbing loops for lashing extra gear, and a pass through strap on the back that slides over the handle of a rolling case. That last feature makes this the second bag in a two bag system if you also travel with a suitcase.
Weight, capacity and what carries well
The published empty weight is 2.99 pounds, and it is the standout number on this listing. A 35 liter travel pack at under three pounds is light. For comparison, a 35 liter hard shell cabin case in this catalog weighs six to eight pounds, and a wheeled business case with 24 liters weighs over eight. Every pound saved on the bag is a pound of clothes you get to carry within the same limit, and on carriers that weigh cabin baggage against a 7 or 8 kilogram allowance a three pound pack leaves you real room.
Thirty five liters of usable volume in a soft pack is close to the whole envelope, because there is no shell thickness, no handle channel and no wheel wells to subtract. The published exterior of 12 by 10 by 22 inches is roughly 2,640 cubic inches, or about 43 liters, so a 35 liter usable figure is credible and consistent.
What the pack does not have is wheels, and that is the whole trade. Thirty five liters packed for a week weighs somewhere between 20 and 30 pounds, and you will carry all of it. If your route involves long terminal walks, stairs, cobbled streets or public transport, that is a good trade. If it involves standing in lines with a heavy load, it is not. Wheeled travel packs that split the difference are covered in the Osprey Farpoint wheeled travel pack and the Osprey Fairview.
Security, warranty and the review base
The main opening has lockable zippers. That is a useful provision on a bag that goes into hostel lockers and bus holds, and it is worth stating what it buys. A lock on a coil zipper stops a casual hand and stops the bag falling open. It does not stop anyone determined, because a coil zipper can be split with a ballpoint pen and closed again by running the sliders across the split. Keep documents and cash on your person.
No warranty term is published on this listing. No period, no coverage description, no exclusions, and nothing about airline handling damage. Cotopaxi publishes coverage on its own products generally, so read this as a listing gap rather than an absence of policy, and get the terms in writing before ordering.
The review base is 4.7 from 29 ratings with a rank of 75th in its Amazon category. Twenty nine ratings is a very small pool and a high average on a small pool tells you the early buyers were pleased, not that the fabric survives two years of bus holds. Read what there is, and weigh it accordingly. Comparable travel backpacks with different capacity and price positions sit in our backpacks section, including the Victoriatourist carry on travel backpack.
Who should buy it and who should not
Buy it if you want one bag, you would rather carry than roll, and a clamshell opening with real hip belt support is what you have been missing. Under three pounds for 35 liters is the best weight to volume figure on this site. Skip it if you carry a 16 inch laptop, if your knees or back are the constraint, or if you need a large body of durability reports before buying, because there are only 29 of them. Get the fabric denier and the warranty terms in writing before ordering.
