Product review: The One Bag, extendable and collapsible

Yet again, I have you guys to thank for this one: What did I think of The One Bag, asked a reader [Maureen] whose name is now lost in the mists of Facebook? I scrabbled around on Google, found the bag, and thought that I’d really like to see it in person. I was intrigued because, like the Kobi Pet Carrier I reviewed in March, the carrier expands in length on demand. Unlike the Kobi carrier, it can be collapsed into a tidy rectangular packet for storage. The folks at One for Pets kindly agreed to send me one to poke and prod, and it arrived last week. I have not been paid for this review, and I did not promise (and One for Pets did not request) that it would be positive. The One Bag carrier costs more than $50, so I will be giving it away to one lucky Dog Jaunt reader (total value: $140). I’ll provide the giveaway details in a separate post on Monday, May 7, 2012.

The One Bag comes in two sizes. The small size is 16″L x 9″W x 9″H pre-expansion (and can gain 5.5 more inches in length); the large size is 19″L x 11.5″W x 11.5″ H pre-expansion (and can gain 4 more inches in length). Please note that these measurements were taken from the company’s website; I found that the large size had slightly different measurements in person (see below). I asked for a sample of the large size, given that Chloe stands about 12″ tall at her shoulders. I asked for it in black, because I like to minimize the perceived size of a bag that pushes (and in fact exceeds) the maximums of many U.S. and international airlines. The rep at One for Pets cautioned me that the large size “is not designed to fit under the airline seat although it may fit under some. The small size definitely fits under most airlines’ seats.” She’s right, of course, but I asked for the large size anyway, since most of the inquiries I get are from people who own a larger small dog like Chloe.

The carrier arrives in its storage bag, collapsed into a rectangle 19″ long, 12″ wide, and 3″ deep.

Assembled, the large size measures 20″ long at its base, and 14.5″ long at its top (the ends are therefore angled, as you can see in the first picture above). At its base, the carrier is 11.5″ wide, narrowing to about 9.5″ wide at its top. At each end, the carrier is indeed 11.5″ tall. Between the ends, however, it’s more like 10″ tall (but see below). Each end can be unzipped so that gussets provide more length. Each adds about 2.25″ of extra room. (The padded insert that stiffens the bottom of the carrier has two short wings, normally folded under and secured with Velcro tabs, that can be extended to fill the new spaces.)

The One Bag is made of ballistic nylon and comes in olive, navy and black (the site also shows a brick color, but that’s apparently not currently offered). It has generous mesh ventilation panels on four of the five possible sides; the fifth side is occupied by a luggage handle panel, created when two parallel zippers are unzipped. Behind them is a very clever seat belt solution, allowing the bag to be secured with the lap portion of a car’s three-point belt.

There is a pocket on one of the ends — not huge, but big enough for a roll of poop bags, a minimal leash, and your pet’s travel papers, folded into quarters. Access to the bag is via either end (both of which have zippered doors). The top, too has a zippered opening, but it would be a tight fit for a pet. It wins points from me, though, for being see-through mesh and for the zipper, which allows you to reach in easily and pat your pet.

The shoulder strap has a comfortable pad. It clips at either end with a sturdy nylon buckle, so you won’t be using it as an emergency leash (unlike the Kobi carrier’s strap). There is a tether sewn inside, at the top of one of the long sides. This carrier is all about zippers (there are three on each end, three on the sides, and one on the top), so it’s a very good thing that the zippers are good-quality and function smoothly.

Chloe in the large One Bag, not yet extended at either end

As you can see, Chloe is very comfortable in the large-sized One Bag. What you can’t see is that she chose to remain it it for, literally, hours after I took her picture. She was interested but not alarmed by the activity involved in extending the ends while she was inside the carrier; even the ripping Velcro sound of the base extensions being unfolded didn’t seem to upset her. She was content even before the extensions were deployed, but willingly stretched out to fill the full space when it became available to her. I would have no problem carrying her in this bag, since although the bag is 10″ tall at the height of the support “beams” that run along the long sides of the carrier’s top, the top panel itself will easily lift up another 1″ to 1.5″ as your pet pushes against it.

Will it work as an in-cabin carrier? The small size would work like a dream, no question. The large size is iffy. Its height would work, I think, in most situations. Because the ends are the same height and width, turning the bag on its side doesn’t solve any problems (and in fact, the rectangular padded base would not work on a trapezoidal side). The ends are tall, and stiffened, but the middle part of the top panel is significantly shorter. It, too, is stiffened (with the support “beams” I mentioned in the last paragraph), but those bars are only 10″ off the ground — and without too much effort, you can press them down to about 8″ off the ground. The panel suspended between them is unsupported, so would mold itself readily around an under-seat electronics box.

You cannot, however, shorten the padded base of the carrier (compare the SturdiBag, where you can access the stiffener and saw off an inch if you like), so you’re stuck with the basic 20″ length. That’s a long bag, comparable to the extra-large SturdiBag, which sticks out significantly into your legroom area. On balance, I’d choose to use the large One Bag carrier as a car travel bag, or a bag that I’d take on the bus or other public transit, and then use at work as my pet’s day lounge. If you own a pet that is 9″ at the shoulders or less, you should give serious thought to buying the small One Bag for an in-cabin carrier.

This is a good, quality carrier — a lot of thought has gone into its design, and the construction is impressive. When I started writing this blog, I jeered at collapsible carriers (what need? was essentially my attitude), but I’m not jeering any more. The One Bag returns easily to its storage bag, and that’s a very nice feature indeed.

    So glad to see your review of The One Bag, I am the elusive reader requested your opinion of this bag after googling expandable dog bags. The One Bag sounds impressive, and the perfect size for Lily, our Havaneese/Terrier mix. Dogs have always been part of our Family but after losing all three in eleven months( a neopolitan mastif , yellow lab, and australian shepherd) We deciced to try a smaller version this time round. Who knew it is a completely different experience! Lily the Havaneese weighs in at 21 lbs and Sasha the Shih Tzu is a hefty 9 pounds. At any given time they can be found on our lap, at our feet and yes, in our bed. Sasha would be easy to fit under an airline seat, but Lily will require the thought and angst that brought me to your site in the first place. Thank you for keeping us informed on the bests ways to navigate pet travel. Please keep me in mind for this bag. Thanks Again, Maureen Gutman

  • Oh, thank you, Maureen! I looked and looked for your comment, but just couldn’t find it. The giveaway will start on Monday, and I surely do wish I could rig the results. Fingers crossed for you and Lily!

    This bag seems perfect for Chuy, my Westie. It’s diffcult having a big small dog. He weighs 21 lbs right now and most carriers are too small for him. I take him with me around the city (cabs, subways, etc.) so a comfortable but portable carrier is a must for me. I will definitely be crossing my fingers for the giveaway!

    We are travelling with our 7-month old Cavalier, Sisu, in June to Finland. I have read many of your blogs about overseas travel, so thought I’d add something I hadn’t seen or paid attention to. I just discovered that the 15-digit ISO standard chip that we need has to be readable at 134.2 kHz or we cannot enter the EU. Some microchips are 125 kHz, but packaging does not specify that detail. You can buy you own scanner to make sure that it can be read, but it costs about $325. It is very important to have this correct early, because the rabies vaccination has to occur AFTER the microchip placement and 21 days before travel. Also, Finland is one of the countries that requires medication against tapeworm no more than 5 days before entry into the country. Luckily we have a USDA (APHIS) office in our city, otherwise it would be very tight to get the medication and documentation from the vet, mail it to the authorities, and get it back in time to board the plane. Also, the APHIS officer told me there are almost always errors on the paperwork, so she gave me two appointments – a second to come back with revisions. I’ll let you know how it goes – it’s a bit nerve-wracking!

    Heather,
    I just did the APHIS paperwork for a trip I’m going on beginning Friday. I was also really nervous but read and re-read the requirements and the USDA office was so super easy and the person was pleased with everything I did. Did they send you a list of common mistakes to avoid? My suggestions for avoiding common mistakes: Type what you can before you go to the vet, make sure to use European dates (month first), everything should be signed IN BLUE.
    Susan
