Review: Really great little pack!! - Warning: long review I’ve had this pack for a year. Used it for hiking and day trips where I want my hands free or need to bring a bit more with me. It's also great for taking to the farmer's markets, it can hold a lot. I honestly really like this bag. It has all the right pockets, it’s a good size (not for overnight trips) and is lightweight. It’s held up really well with rips, stains or broken zipper after a LOT use in the desert, forest and beach environments. I'm rough on my day packs so I'm super impressed given how inexpensive this was. I fill the water water bag, throw in sunscreen, emergency clothing, maps, an extra bottle of water, a flashlight, an emergency kit, phone with extra battery, some personal items and food! It surprisingly holds it all and doesn’t feel too bulky or heavy. Sometimes I even put in water shoes. I find it very comfortable and well balanced for such an inexpensive pack. The bag is quick drying, not truly waterproof, but it doesn’t get soaked through right away in a light rain. I’ve had no issues with the water bag leaking and the mouthpiece works fine. It’s pretty easy to fill and clean, but all of these types of bags are a little awkward. The big name water bags have given me more problems than this one has. Although at this price? A year or two of use seems pretty reasonable. I, of course, have a few complaints. The first is my ONE BIG PET PEEVE about backpacks. The water bottle pockets are ‘almost’ big enough for my water bottles. I can manage shove one in there, but it’s really difficult. Impossible if the bag is full and I always like to carry extra water. This issue isn’t unique to this pack, all of the packs I have are the same. I don’t use the oversize bottles, just the normal insulated ones. WHY can’t they make the pockets just a half inch bigger so the bottle fit?? The second improvement I’d love to see is a key clip inside one of the compartments. Maybe the clip on the outside is intended to be for keys, but I wouldn’t have my keys dangling on the outside of my pack for the day. I use it for a retractable clip with a compass. A clip on the inside would be great so I don’t have to dump and search for my keys at the end of the day. I would have liked double zipper on all the compartments, only the large one has them. Finally, the strap material could be a bit softer, but this really feel like I'm almost finding something to complain about. I don’t notice it at all unless I’m in a sleeveless shirt. If you need a really good day pack for hiking or day trips, I don't think you can go wrong with this one.
Review: All Seems Quality - Two Thumbs Up - Update: 9/10/25 I wore it for several hours, (in extreme heat and two days in rain) at a WEC race where I walked for miles and had no cover overhead (from sun or rain.) It did not disappoint. The water repellent bag in the zipper pouch on the very bottom is a great idea. Given the packs small size, you can load it up pretty good. The straps and padding and material are all excellent. It's comfortable even with a considerable load. The pack itself is light weight. There's a strap at the chest and one at the waist if you desire to use it. I found the waist one actually helped bear the weight. My original review (before using it) is below: I might come back to give it five stars, but I haven't used it yet. I've never had one of these (of any brand) so I can't compare it to anything else. The main thing, the bladder, is constructed well and rests in an insulated compartment, (as the description says.) I will be wearing/using it a lot at COTA in Austin TX in two weeks and if there's an issue it should show up then. The breathable straps and padding exceeded my expectations. There are other pouches or pockets to store other smaller items. In the largest pocket I can carry my foldable chair. Surprise! With the bladder (two-thirds full) and the chair the entire rig weighs 10 lbs. Not bad for hiking or longer walks. If you are a runner, you won't want to pack so much, certainly not a folding chair. The materials don't look/feel cheap. The attached straps (one at the waist too if you want it) are easily adjustable. I can see where it's lacking anything. We'll see, soon enough.

### ⭐⭐⭐⭐⭐ Really great little pack!!
*by D***B on July 17, 2025*

Warning: long review I’ve had this pack for a year. Used it for hiking and day trips where I want my hands free or need to bring a bit more with me. It's also great for taking to the farmer's markets, it can hold a lot. I honestly really like this bag. It has all the right pockets, it’s a good size (not for overnight trips) and is lightweight. It’s held up really well with rips, stains or broken zipper after a LOT use in the desert, forest and beach environments. I'm rough on my day packs so I'm super impressed given how inexpensive this was. I fill the water water bag, throw in sunscreen, emergency clothing, maps, an extra bottle of water, a flashlight, an emergency kit, phone with extra battery, some personal items and food! It surprisingly holds it all and doesn’t feel too bulky or heavy. Sometimes I even put in water shoes. I find it very comfortable and well balanced for such an inexpensive pack. The bag is quick drying, not truly waterproof, but it doesn’t get soaked through right away in a light rain. I’ve had no issues with the water bag leaking and the mouthpiece works fine. It’s pretty easy to fill and clean, but all of these types of bags are a little awkward. The big name water bags have given me more problems than this one has. Although at this price? A year or two of use seems pretty reasonable. I, of course, have a few complaints. The first is my ONE BIG PET PEEVE about backpacks. The water bottle pockets are ‘almost’ big enough for my water bottles. I can manage shove one in there, but it’s really difficult. Impossible if the bag is full and I always like to carry extra water. This issue isn’t unique to this pack, all of the packs I have are the same. I don’t use the oversize bottles, just the normal insulated ones. WHY can’t they make the pockets just a half inch bigger so the bottle fit?? The second improvement I’d love to see is a key clip inside one of the compartments. Maybe the clip on the outside is intended to be for keys, but I wouldn’t have my keys dangling on the outside of my pack for the day. I use it for a retractable clip with a compass. A clip on the inside would be great so I don’t have to dump and search for my keys at the end of the day. I would have liked double zipper on all the compartments, only the large one has them. Finally, the strap material could be a bit softer, but this really feel like I'm almost finding something to complain about. I don’t notice it at all unless I’m in a sleeveless shirt. If you need a really good day pack for hiking or day trips, I don't think you can go wrong with this one.

### ⭐⭐⭐⭐⭐ All Seems Quality - Two Thumbs Up
*by J***N on August 25, 2025*

Update: 9/10/25 I wore it for several hours, (in extreme heat and two days in rain) at a WEC race where I walked for miles and had no cover overhead (from sun or rain.) It did not disappoint. The water repellent bag in the zipper pouch on the very bottom is a great idea. Given the packs small size, you can load it up pretty good. The straps and padding and material are all excellent. It's comfortable even with a considerable load. The pack itself is light weight. There's a strap at the chest and one at the waist if you desire to use it. I found the waist one actually helped bear the weight. My original review (before using it) is below: I might come back to give it five stars, but I haven't used it yet. I've never had one of these (of any brand) so I can't compare it to anything else. The main thing, the bladder, is constructed well and rests in an insulated compartment, (as the description says.) I will be wearing/using it a lot at COTA in Austin TX in two weeks and if there's an issue it should show up then. The breathable straps and padding exceeded my expectations. There are other pouches or pockets to store other smaller items. In the largest pocket I can carry my foldable chair. Surprise! With the bladder (two-thirds full) and the chair the entire rig weighs 10 lbs. Not bad for hiking or longer walks. If you are a runner, you won't want to pack so much, certainly not a folding chair. The materials don't look/feel cheap. The attached straps (one at the waist too if you want it) are easily adjustable. I can see where it's lacking anything. We'll see, soon enough.

### ⭐⭐⭐⭐⭐ Small backpack with nice features!
*by S***. on June 20, 2024*

Updated: After using this backpack for over a year, I upgraded its rating to 5 stars. I use this pack almost exclusively. It worked extremely well on two walking trips in Japan in 2024 and 2026. Having the hydration pack is great- mo having to fish around to retrieve a water bottle. 18L seems small, but it is amazing how much fits into this pack. I was looking for a smaller backpack for daytrips. I have a 40L Ecogear Snow Leopard pack that I LOVE but the company is no longer in business. So far I like this pack for the following reasons: 1) lightweight, but roomy. The main compartment is tall enough to hold my knee pad that I carry to yoga class. I can easily stuff my rain jacket and a down jacket or vest inside at the same time. 2) Built-in rain cover - one of the reasons I picked this bag over others of similar size: the rain cover is essential on multi-day hikes/walks to keep your gear dry. 3) 2L bladder - works well and it's nice to have the option of either shoulder to run the hose out of. 4) Comfortable shoulder straps - at first I thought this pack was too big for me (5'-1" tall) but I actually like having the shoulder straps away from my armpits - this means no chafing for long hikes and plenty of room to move my arms (I use trekking poles). Cons: Although you can use a bladder, sometimes you just need a water bottle! The side pouches are very small and it's difficult to fit wider bottles into them, but since there are no loops to hang trekking poles, I can see using the mesh pouches to hold the poles and running them through the outer straps. It also would be nice if every zipper was set up with two zippers - only the main pouch is set up this way. The hip strap is adequate, as the pack is small, but I would have liked a padded hip strap. Separately, I use a Boosteady camera bag that I attach to the sternum or hip strap to keep my phone handy for taking photos along the way. So far I have used the backpack for getting around the city; looking forward to trying it out on longer day hikes and taking it to Japan this coming October for a 7-day walk in Tohoku.
