The perfect daypack

I bought this pack specifically for my trip to Yellowstone and Grand Teton. The hydropack is great for convenient hydration without having to stop and dig through your bag. The bag looks like it’s on the smaller side but fits a lot more than you think it will. I also love the way it is structured for a woman’s build. The back panel has venting on it so even when you sweat it’s comfortable and doesn’t hold a ton of moisture. I really recommend this product and thought it was perfect for my 3 to 8 mile hikes.

Well-made hydro pack for short hikes; great color

Perfect size for a regular day hike. The pretty bright sky blue color is sure to be seen from a distance. Gregory produces stacks in some really cute colors! About the bag: I can fill up the bladder with water and ice, include snacks, a first aid kit, a couple of emergency tools, bug spray, sunscreen, an extra thin layer. The sternum strap is magnetic and the drinking tube conveniently connects to that to keep it out of the way. I love the zipper pulls, very comfortable to use, and easy to clip stuff on. The shoulder straps contours nicely, even though I’m 5’1”, and pack isn’t too tall. The waist strap is skinny, so there are NO hip pockets. I don’t pull these straps tight, just connect both around my waist to keep the from dangling. I also have an orange 28L Gregory backpack that I love taking to trails that are farther away. Gregory offers some really useful features in their backpacks. (I only wish Gregory made these packs in colors like fuchsia, and bright orange or red.)

Great backpack!

I absolutely love this backpack! It’s compact but holds a ton and the various compartments are really smartly designed. It’s incredibly comfortable to wear.

First and great day pack!

I have been getting in longer day hikes and this pack has been really great. I have never had a water reservoir and this one was so easy to use especially because it came with the bag. It’s also the perfect size for me and still holds a good amount of stuff! Also, got it super wet in the rain one day and it dried very well on its own, the stuff inside stayed dry.

The best backpack I ever had !

Love the color, and the size is perfect for daily hike. It’s a lightweight too, so it’s a plus.

Perfect pack!

Size Bought:
Small

Compared to my old pack (camelback), this Gregory pack is lighter weight with better distribution across my back and waist, easier to clean with a leakproof bladder, and has multiple zippered compartments to separate dog waste from my extra layers and snacks. My only negative comment is the magnet for the water hose does not hold the hose, but I am able to keep it in place with other straps. Overall, I love this pack!!

New fave pack

[This review was collected as part of a promotion.] I switched packs recently and couldn’t be more happier. I love the side pockets and zipper pouch. This pack gives me more room than I had previously.

Best Day Pack I Have Ever Owned!

[This review was collected as part of a promotion.] This is the best day pack I have ever owned. I am a gear snob and am pretty picky, but this bag is IT for day hikes! I have been using another brand's hydration pack for hiking and mountain biking but this has immediately taken its place. There is ample room for layers and lunch in this pack. Not to mention the organizational pockets and the out outside bottle pockets that are great for quick access to items or additional beverages. Materials and construction of the bag are great quality and I can tell everything is going to hold up for years to come. This is also my first experience with the Gregory hydration bladder and I have to say it's much easier to open and operate than my old one. The only negative to the pack is the waist belt does ride up a bit if you're wearing a shirt made of a slippery fabric. Although this was a #giftedproduct I would buy it again for myself and my friends!
