Inexpensive bag of pretty good quality
I bought this as a treat bag for my dog. When training him, I like to use dessicated beef lung as a reward. However, the bag of treats is big (probably gallon size) and inconvenient to carry on a walk while also handling a large dog that hasn't quite gotten the message yet. I took a page from a trainer that I know and bought this bag to keep the treats close at hand without having my hands full. I dump some treats in, leave the zipper open, and can reach in to reward my dog whenever he does something right. When I'm done, I zip it shut and hang it up out of reach. The treats I use won't go bad inside the bag so I don't have to take them out each time I'm done. Most of that probably won't apply to you, so here's what I can tell you about the bag. It's very light but reasonably well made. I wouldn't want to carry anything too heavy in it (I probably wouldn't go much heavier than a phone, keys, and maybe a bottle of water) but it seems reasonably solid. It doesn't appear as durable as the Jansport I had many years ago, but this one cost me less than $12 at the time I bought it whereas the Jansport would probably be close to $30 if you adjust for inflation (wish I'd kept it...) It's easy to adjust and stays where you put it. The zippers are decent quality and have not yet jammed. Not sure about the water resistance-- it looks like it would keep the contents dry in case of accidental splash or light rain, but I suspect anything more would soak right through. Since it's not designed to be waterproof, that isn't a knock against the bag, just a statement of fact. You could probably spray it with Scotchgard or similar if you wanted a little extra water resistance but I didn't bother. If you need a very inexpensive knock-around bag to free your hands on a walk or hike, this is as good a choice as any. It's durable enough to survive a couple of bumps and scrapes (or an 85 pound dog sniffing it and pawing at it) and works well. It's just the right size to give you more carrying capacity than your pockets can hold, but is smaller and lighter than even a small cross-body or sling bag. If you find yourself carrying enough stuff that you wish your pants had an extra pair of pockets, this bag will probably work for you.

Spacious, sturdy, nice color
Summary: Overall- this pack is very spacious, seems very well made, and it's well worth the purchase price, but if you're just looking for a small pack to carry id, cash, and keys, this one would be overkill. The pack is a really nice color and feels sturdy and well made. I was looking for one that wouldn't bounce against me or get caught by brush on longer walks, hikes, and runs. It's somewhat bigger than I had envisioned, but that's my own error as the product description is accurate, and on the plus side it's capable of holding a lot of items. As shown in my pics, it easily accommodates a paperback book, 20 oz beverage, phone, keys, wallet, mace, pocket knife, mask, and med containers with plenty of room. It feels comfortable and looks good as a waist or shoulder pack. The back and sides (where it will press against hips) of the pack are both padded and covered in a breathable mesh. I didn't realize at first that there was a way to secure the extra strap lengths to keep them from dangling, so in case anyone is, like me, not mechanically intuitive, once the straps are the right length, you can slide the triglide adjustor all the way back toward the pack to keep the free ends from flapping and looking dorky.

Can even fit a water bottle and more!
I was looking for a crossbody bag/fanny pack that I could fit a weirdly large amount of stuff in, without it standing out too much or being bulky. It can fit a 20 floz plastic bottled water from the store, a small collapsible umbrella, and a small bug spray container, PLUS the usual keys, phone, wallet, small hand sanitizer, chapstick, granola bars, etc!!! So I can go on pretty long walks/hikes with this thing without having to carry anything in my hands. I wear it as a fanny pack for hiking, but it easily converts back to a crossbody bag for for casual errands and such, just adjust the length of the straps. I like the two inner pockets for organization. Tip: for quicker access to the secondary zippered pocket in front, fold up the long thin flap of fabric that normally covers that zipper - it'll stay. That way you don't have to use two hands to peel back the cover and unzip it.

Great fanny pack for father of two!
I've been shopping around for a good bum bag/ fanny pack for a while and I'm happy to say that this one finally fits the bill. I'm a father of two, and work in the hospital so I prioritize utility over looks - luckily, this bag fits both bills. First off, great quality in the bag. Its got a nice texture and color gradient for the gray. Second, this bag can actually fit a ton of stuff! A lot of the previous fanny packs I bought, couldn't expand - the zippered section opened up fine but then the bottom of the pocket sealed off into v-shaped dead end, which made it difficult to store multiple items. This bag expands and in the pictures I try to show how much it does. I comfortably fit my iphone 6+ , wallets, keys, and other random items with lots of room to spare. Back of the bag is made of a breathable mesh which I very much appreciate in the hot summer. Straps are easy to tighten as well and can be easily tightened when you're wearing it around the waist by grabbing the ends (think tightening a backpack strap except for around the waist). They also have a little elastic band to help prevent loose ends from flailing. There is one main zippered pocket with a key chain holder and two in-seam pockets and another front, smaller zippered pocket for smaller items. I recommend this bag to anybody - guy or girl as its conveniently unisex - looking for a nice practical bag to carry belongings. My only recommend is to maybe a hidden zippered pocket in the back for private items such as a passport but that's not a dealbreaker for me. Overall, great bag!

Just buy it!
I have been customer of this brand and model for over 4 years and have bought at least 4/5 items for me and for family. Always the same result: good qulity, comfortable, fits all my needs....if you are looking for this, do not waste your time looking for others!

Good pack for small items.
Well made item but the zippered opening was too short for my needs ( to hold a book).

Child's life saving medicine
I love this product as I was looking for something durable and easy to open, I went through countless other items and crazy priced before I found this one! My child has been diagnosed with seizures, and this is what I needed to have to carry around her medicine. Among other things such as wipes, travel sized toiletries, an 8oz bottle of water, hand sanitizer, alcohol pads, bandages, lip and skin protection, snacks, and medical information. Great for going to the park, lake, hiking, or on the go. I'm super happy with this product because I'm a bigger person and the straps actually fit around me. I chose this red because it reminds me of a medical bag without looking like one, but we might take something to it to mark that it is for medical use only. I may have to invest in one that is strictly for snacks but as long as I have this medication on hand, in its easy to reach for and unzip bag, I'll sleep a little better at night. When we are home it is hung in one central location and then I don't need to worry about moving it from my purse to the cupboard, or perhaps forgetting it altogether. You can wear it different ways and I love how soft the mesh padding is so there's nothing digging into the skin. I wasted so much time and money on other products that fell apart or the zipper broke. This medication for my kid isn't cheap, so it's nice that a product like this can last without costing me my other arm and leg.
