          Perfect for hiking with your dog!

          Love this fanny pack for hiking with my dog. It’s very comfortable to wear. The extra padding feels really nice on your body. The large pocket easily fits a retractable leash handle so I can be hands-free with my dog. I can even fit my iPhone 14 Pro Max in the small front pocket. Love the various other pockets for organizing snacks and your wallet. Really impressed with the overall quality as well. Highly recommend!

          It's a hit!

          Got this for my 11 year old daughter as a Xmas gift, and ut was a big hit for her. She is wearing it over the shoulder as a cross body bag, and it's just about the perfect size. She can organize her things and it is stylish looking, too. Seems pretty well made compared to more popular brand name bags. Would recommend.

          Great for active wear

          This is a solidly designed fannypack/crossbody bag, it looks and feels high quality. I was torn on the color variety and ultimately settled on plain black for versatility and have no regrets. This is a great discreet bag for active wear, particular on hot sweaty days with the mesh backing. I love the design on the main pocket with the side "bellows" to keep it from spilling open. At 2.3L it has surprisingly good capacity and storage options. A solid choice for packing a little heavier for a longer day!

          crossbody bag full of features

          Well made carrying bag with lots of pockets and features, like key hook, external loops for clips and charms, RFID pocket, inner theft detergent pocket, mesh back for sweat, reinforced handle, and expanding main compartment. You can see it all in the item description.Only thing I will note is that this is for normal sized people and not petite, unless you don't ever want to wear it as a fanny pack like the description. I wear women's size 4 and the waist on its smallest size will still fall down my legs. It's fine since I like to wear most fanny packs crossbody style but be warned.Other than the lack of adjustable size everything else about this bag is very well done.

          Love this pack!

          I have several fanny packs, and this one is great! It is large enough to hold a lot of supplies but has pockets or compartments to keep it all organized! I hate rummaging through a big open bag for that one small item. The strap and buckle are more substantial than others, making this more durable. This also allows for adjustments on both sides of the buckle for the perfect size adjustment. Oh, and don't forget the handle on top! This is a must have!

          Padded and lots of ways to carry

          This is different, which already is a star in my system. It has that weird padding that feels almost like those rolls of packing foam but thicker and this is only the 2nd bag I have ever owned that had that. I love it. It feels neat but it’s also basically like all your items are packed for shipping so they are better protected.It’s light, and has plenty of pockets so you can have some type of organization which is more functional for me than digging for change or chap stick in the bottom of a single pocket bag.The fit is adjustable so you can wear it in the style that you prefer and the quality is good. Also you can just hold it by the handle the top like a little mini bag.I thought this would be like a hiking only kind of purchased but I can see myself using it as a little essentials bag when I am in the mood too.Definitely would recommend this one! It’s kinda quirky and I really like it!

          Sleek stealthy bag with RFID protection

          I really like the slim low profile design of this bag. It can be worn concealed under a jacket if you needed for extra safety. But for casual use I like it because it isn’t bulky but can hold a lot of my every day carry items. It also has an RFID blocker to protect your cards. This is very light weight and made of good durable materials. It feels comfortable to wear and has a sporty look to it. This is one of my favorite fanny pack type bags. Can also be worn across your body.

          Spacious and Great Quality

          The bag is a bit bigger than expected for a waist bag. it is perfect for a sling though, which is what I would use it for anyway. It has plenty of storage. It has 3 main compartments and 1 zippered RFID section inside of the main compartment. it is light and well constructed. I used it on my recent park trip and it was perfect. I was able to fill it with my essentials (phone, battery back-up, wallet, keys, and a small snack. I still had plenty of space left over. The mesh on the back side helped with airflow and kept me from getting sweaty where the bag was. I have not tested the RFID blocking, but it's a nice thing to have. Overall I am very pleased with the sling.

          Tons of storage. Highly adjustable strap. Durable construction.

          Really nice fanny pack with a butt load of pockets. The strap, buckles and zippers all feel durable, and each pocket offers enough storage for various different things.I really like the color. Very vivid and clean looking. The strap is adjustable to fit pretty much any waist size.I've been using it for a few weeks now and it has held up great to rain and normal wear and tear. Will be picking up more Waterfly products if I get the chance.

          Versatile Waist or Crossbody Pack

          I have needed a nice small bag for exercise and for travel- so I was excited to try out this fanny pack that can double as a cross body bag. My excitement was not misplaced in that this bag is really nice- and super low in price. It has 2 pockets, including one that is RFID blocking on the inside as well as a small ring to attach keys in the front pocket. The mesh on the back makes it more breathable and the strap is large enough to be secure without being bulky. It works great as both a traditional fanny pack or a cross body bag that can be fastened and put on under a jacket (so no one can unfasten it from behind) for extra protection while traveling. This bag by far has more room than any other pack I have used- and is still lightweight and does not feel bulky. I love the blue color as well. Happy to recommend!
