Best pooch pack on the market.

Well constructed! I put multiple bricks in the pouches to simulate a load for my Rotty for when we go backpacking. He loves it and is way excited to put it on. He even swims in it and it holds up quite well. Chest straps are barely long enough but he's 150 lbs

I really enjoy trail hiking with my dog and longer walks. It fits a 6ft leash, my keys, a few poop bags, cell phone, a snack, treats, and a collapsible water bowl for my dog. It's durable and love that the treat bag actually stays open when rewarding my dog. It's nice to hike and not wear a backpack. It clips securely to my belt and around my waist.
Perfect for any dog owner looking for a classy treat pouch that doesn't scream "dog trainer" It's a natural color and blends in with your jeans as well.

This pack is perfect for my needs. I honestly can't think of anything I'd change about it. So, so comfortable. Hip belt pockets large enough for passports. Top loader but with good middle access. Rain cover. Deep side mesh pockets for water bottles or flip flops (which suck to pack). Flexible mesh outer pocket that can hold small laptops, tablets, and/or books. Top pocket is huge and can hold tons of stuff (but warning: fill it too much and you may bump the pack past carry on dimensions). 30 pounds on this pack feels like 15 on any of my other packs. Compression straps all over, and they work very well. Oh yeah, it also looks great just in case you care about that (yeah, I kind of do, sorry).

My search for the perfect travel pack is over. Gregory wins. And this from someone who pretty much loves everything Osprey makes.

Love, love, love this doggie backpack! It fits perfectly and he's comfortable wearing it. I also like that it's not as bulky as a lot of the packs out there since I'm wanting to use it when we go on runs for keys, phone, and water for both of us. Very pleased with the quality, appearance, comfort level for my dog, and the price was unbeatable! Would highly recommend if you are wanting something that still has space for storage but it more streamlined and less bulky than a lot of doggie backpacks out there. :)

Absolutely LOVE this bag. I had to wait nearly 9 months to buy it for my 5.5lb Seizure Alert dog as an occasional working item for large crowds and things to keep him safe from being stepped on, etc. It's hard to find but I finally got one and it's amazing. It's soft to the touch, the outside fabric is kinda like thicker T-shirt material but it is layered on top of a thicker padded nylon type inner material. The shoulder strap is very adjustable and will fit comfortably on a Plus Sized person as a cross body bag. The pocket up front holds my phone and emergency medical info. The large pocket in the back holds my leash and a chewie for my dog. The two inside pockets where the dog goes hold my poop bags, a small bottle of hand sanitizer, a hair tie, and some lip balm. My dog is very well trained, he won't mess with the items in the pockets but if you're planning to leave your dog in this bag, don't put anything that is toxic in those inside pockets, they do not zip shut.
 My dog is a long haired Chihuahua, 5.5lbs. He fits very comfortably in this bag, while wearing his Service Dog vest over a sweater if need be, and with my emergency medications in his vest. He is not squashed. I would say he stands about 9" tall.
 If I had to complain about it I would say that if you're going to wear it for any amount of time with the dog in it, that it could use a shoulder/neck pad to keep the strap from irritating your neck. I'm looking into getting a sheepskin strap cover for it. Considering how hard it is to find this bag, I may purchase a second one to put away in the near future.

I bought one of the higher end packs, the SATL pack. The quality of this pack is outstanding. It has been well thought out. There are several parts of the pack that I like the most, notably the ability to access the bag via several openings. Also, the ability to fasten items to specific spots in the bag.

I give a full review on my blog, found here:

I have several carriers for different purposes. I have used this one for several outings for my 6.5# Chion.  I have a medium frame and am 55 tall and this pack is SUPER comfortable. It has been easy for me to expand and zip back up and the inside is roomy and has plenty of ventilation. What is great about it is your pup can go incognito!! I highly recommend it.

Just went on a two day hike, the pack was perfect about 35 lbs loaded very comfy and durable. Simply the best pack I have owned. Probably the last one I will buy with its lifetime warranty I never have to worry about it again.

Search no further this is it. This pack is great. I've taken it out numerous times and it has more than enough room and pockets. Great design. Wish I could use it every day.

Incredible quality!  The back pads are incredibly comfortable.  I can't say enough about this pack.  I am sold on Deuter.  I purchased a Fox 30 for my son and he loves that pack as well.

I loved this bag when I saw it here on Amazon, but after I purchased it I was a bit leery about whether or not I picked the right bag. It's hard to buy items like this online where you can't really touch it, look closely at it etc. I was very very happy when I got this in the mail. It was well packaged and as soon as I pulled it out of the box I knew this would be perfect. I bought this bag because it was a bit bigger than the one I currently have. I have a Havanese who had a litter of 5 puppies and in order to get them to and from the vet when shots are due I like to take mama with them to calm them down. The Carrier I have is great for just mama dog, but not mama plus 5 puppies. So I wanted something that would better suit. This bag is perfect. I love the mesh on this bag so that my mam can look out and the zipper compartments are great too. There are places to store items as well like a leash or treats or a collapsible fabric water bowl. The hand straps are thick and well made and the attachable shoulder strap is pretty neat, it curves at the part that you put on your shoulder so it molds better to your body and doesn't dig into your skin when it's on  your shoulder like some other shoulder straps I've had on other carriers. It's extra padded as well. The color is okay, I'm not a huge fan of pink, but I planned to buy more of the same bag if I like this one and color coordinate each bag to each dog (the reason- some of my males mark the girls carriers if I use them by mistake). The padding on the inside is nice too. It's one of those small faux sheep fluff looking dog beds. I can take it out, wash it and put it back in too, which is nice. Love this bag and would recommend this to anyone that has a "larger" toy breed dog or small dog- Papillon, Havanese, Lhaso Apso, larger Shih Tzu, Boston Terrier, Min Pin, Coton de Tulear, etc.

My dogs love this product and feel so useful when the wear it.  Since I have to big dogs, I got the large.  The pockets have a little divider inside, so you can keep your keys, poop bags, water bottles, etc. separate and easily located.  I also got the nylon water dishes that are collapsible and keep one in each.  Best dog product I've ever bought!<a data-hook="product-link-linked" class="a-link-normal" href="/Outward-Hound-Secure-Fit-Dog-Backpack-Large/dp/B000GLI5GE/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Outward Hound?

I have tried at least a dozen new different packs by osprey, deuter, north face, ogio all in the 25-35 liter range.

I am fully convinced this is the best all around backpack made to date by anyone ever.

Airspeed frame is fantastic and I will never buy another backpack without it for anything other than winter sports.
Perfect size, fits a TON compared to other 25-34 litre packs. Excellent placement and amount of internal organization.

Very light.

This doesnt have the ridiculous amount of straps and ties and crap on the outside that a lot of other osprey packs have (they are good for hiking i guess, but for anything short of a multi day hike they seem excessive to me). On that note tho, I will probably never buy another pack that isn't by osprey - they're so much better in so many ways than other brands.

This pack is expensive but well worth it - will last the rest of your life and is phenomenal (I was ridiculously picky shopping for my next pack - pull the trigger on this you won't regret.)

I bike commute fast daily, this is as little back/shoulder sweat as you'll get with any backpack. You will sweat less with this pack and its airspeed backpanel than you will with a 5 liter pack that doesnt have airspeed.

I carry 2 changes of clothes, lunch, sneakers, phone/wallet, toiletries (shower at work), and usually some other random stuff, and this pack holds it all perfectly, I don't have to cram it in, easy to quickly fill/empty the whole pack, and on the other hand the pack is not gigantic and overkill for a daily commute.

I tried the radial 34 at first - it was too big for commuting, and in my opinion way too big for a backpack in general.

This radial 26 seems to fit as much as both the stratos 34 and exos 34 (and without all the straps).The radial 34 fits a TON.

For further comparison, this radial 26 holds a lot more than my north face recon as well, which is 30 liters. I have done no scientific testing, but this pack (and radial 34) basically has 2 huge pockets with some internal organization using mesh or ultra thin fabric. Most other packs with equal or more total volume have one big pocket then a bunch of smaller pockets all around that are made of the thick outer fabric. This results in less total usable volume, especially for larger objects or clothes, etc, even if they might technically have more total volume.

Osprey really outdid themselves this time.

Edit: If you put too much in the smaller of the 2 big pockets (the one closest to your back), it kind of defeats the purpose of the airspeed frame. It makes it so theres no space between the airspeed mesh and your back.
Also this airspeed frame is not quite as "airspeed" as the synchro 20. The actual backpack part of the synchro stays much farther off your back , even when fully crammed with stuff. The radial doesnt leave nearly as much space (in fact when hunched over biking with minimal load in back, there is no space between your back, the airspeed mesh, and the backpack). Still a 5 star pack and still much cooler than any other pack anywhere close to as large as this, but the synchro 20 will keep you noticably cooler.

Great combo pack for the pups, no "bad pieces". however does smell stronger than the 6 inch pack I usually buy. Dogs don't mind the smell of course!

Super satisfied with this backpack. It's made of surprisingly high quality, thick leather. The buckles are a little stiff, but I expect they will loosen up with use. There is a slight odor of vegetable oil, because that's what they sun-tan the leather with. That too grows less and less noticeable with time. Well constructed. Sturdy. Straps are nice and wide. Hangs a little differently than standard packs due to the placement of the strap anchor-points, but I personally think it hangs in a "cooler" way in so much as I wear just the one strap over my shoulder and the pack over my back (broad shoulders required to wear it in this manner, as with any pack). Lots of space and pockets to put stuff in. One zippered pouch inside. No fake buckles. Each one is functional and works as it should. I get a lot of compliments on it daily. When I tell people I got it for less than $50, they freak. I'd stand it up next to any of the $150 leather packs on the market. I'm very pleased. Highly recommend.

Love this bag, only issue I have is it doesn't come in other colors.

I foster animals, and have had many a small dog ride along in this carrier. They feel so secure in here. I have a small dog now that will just crawl in if I leave it laying on the couch.

Pros..
Includes a lanyard to attach to the collar as well, which is awesome if you have a jumper.
Good looking.
Adjustable and comfortable to carry.
Soft-sided but has a stiffer bottom, which maintains more space inside the bag.
Extra pocket up front to carry keys, leash, money.. etc..
People complement it all the time.
Washed up really well, I ran it through a sanitize cycle and then hung it dry, still looks great.
Wears well, I've had it for over a year.

Cons..
No other colors, please make it in pink, or pink and brown like the orange and brown.
No other sizes. I have a 9 lb dog who doesn't fit so well any more, I couple more size options would be awesome.
Needs a way to remove or store the lanyard, only some dogs seem to need the lanyard. Most just want to dive down to the bottom of the bag and chew it up.

All and all, I totally recommend this.

I absolutely love this bag!  I use it everyday.  I carry my Boston terrier's food, water, & bully stick.  Also I've found that I clip his leash or harness on with the clips on the bag when not in use.  The material is high quality as well as the zippers.  I toss (when the water bladder is empty) it in the car or in the corner at work and I feel like it's completely durable enough.  I highly recommend this product. It's the complete all-in-one poochy travel bag.
