solid little pack

Great little pack. Love that it has a 3L bladder. Doesn't hold much more outside of that, but was plenty of water to hike down and up the south rim of the Grand Canyon without weighing you down.

Amazing for a quick hike!

Great material. I use it all the time and the fabric is holding up for the rough AZ terrain!

Excellent Hydration Bag

Wow! This is a great backpack. I upgraded from a Camelback Charm pack and I’m so happy I did. I tend to overpack/be prepared, and I never had enough room for even my cell phone or keys in the Charm while biking. This bag has plenty of room, even with the water bladder full, and also has an adjustable hip belt that helps keep the bag secure while you ride. There’s plenty of room for my phone, keys, a snack, a light jacket, a small first aid kit, and 3L of water (and more stuff if you need). I tend to drink a lot while biking/hiking, so a 3L bag is a must for me. The design of the bag is really smart. I love the curved zipper on the hydro reservoir so you aren’t fighting to get the hose through a small hole. I typically ride 1-2 hours at a time, and it really isn’t noticeable while I’m riding at all. I’ve had other bags that are uncomfortable on the shoulders, and it was truly impressive this one didn’t bother me at all. When I first tried to take the hydro reservoir out, it was a bit cumbersome. However, after filling with water it was actually one of the easiest reservoirs to get into a bag. I have some hiking bags that have the speedclip on the water bladder, but it wasn’t missed here because the curved zippered design of the pouch. I also love the push design to open & close the valve. It’s so much easier than twisting! And the hanging clip built into the bag….genius! I did find the bite valve likes to get dirty, so I will probably be purchasing the bite valve cover. Overall, this is a fantastic bag! I think it would also make a great hiking, festival, or traveling bag. It’s a really smart design & makes staying hydrated easy. Highly recommend.

Perfect for biking and day hikes

This is an excellent pack for biking or for day hikes! Ample space to store necessary things (phone, first aid kit, snacks of course) without feeling weighted down. Love that the water reservoir has its own section and clips in place! The straps, padding, and waist belt portion are great features, allowing for comfortable carrying no matter what the adventure. The only thing I might think to add is side pockets! Maybe with zip closures for use on biking trails so nothing falls out, but it would be especially convenient for hiking-related use. Would highly recommend!

This happens when a company listens!

This bag is awesome! I took it out on a trail ride this weekend, and I loved everything about it. The magnetic chest strap and the easy clip for the hydration bladder took a bit of getting used to, but in a good way! I'm used to the fuss of other bags, and this one just worked so much better! Also, it fit really well on my back -- the water in the hydration bladder is spread out enough and the straps work well enough that I never felt like I was carrying a very heavy load. It was as if I almost wasn't carrying anything at all, based on how it sat on my shoulders/back. I basically love everything about this bag. It's small enough to not be cumbersome, and it's big enough to throw in treats, a bike lock, a jacket, etc. The quick access pockets are such a benefit! I don't mountain bike a ton, which means I can use this bag for other things too -- like fishing -- as it's perfect for some tackle and a telescoping rod/real. I'm not one to carry a purse anywhere, and usually have a backpack with me -- I can definitely see this pack going into the rotation, as again, it's just such a great size and fit! I highly recommend this pack for anyone who mountain bikes or who just needs a good small backpack for day to day living!

I don’t have to carry her water anymore

Purchased this hydration pack for my wife for day hiking not riding. Wanted the smaller sized pack with a full waist belt. The pack height adjustment feature came in very handy, she is 5’2”. Pack works great for her. The water bladder is not as nice as the 3D bladder that came with my Citro 24 pack. It did not have the quick detach hose feature. The 3D bladder features make it more user friendly. Also the hanging clip in the water bladder pouch on the pack is not as easy to use as only my Citro. I am considering replacing with a 3D bladder. Otherwise the pack does the job and now I don’t have to carry her water!

Solid pack

This is a great small daypack. For light hikes and mountain biking where you don't need a 20L+ pack. It's small and incredibly well made. I also use it if I am going to the park with my dog and want to pack a hammock and some snacks.
