I've put it through the wringer

I absolutely love this pack!! The fit is perfect. I can feel the breeze on my back. The carry is super stable. The build is durable. And the hydration bladder it comes with is so easy to refill.

Great Day Pack!

Great reservoir for water storage, good amount of space for the 10 essentials and rain gear and I love the color. Fits great (I am 5''6 and 120 lbs).

Bought the female version for wife...she loves it!

I have the male version of this hydration back pack and after several hikes in hot weather I fell in love with it. Great water capacity and the fact it stays off of my back and keeps me cooler, along with the hip belt to relieve shoulder pressure. Makes it the perfect day pack. I can fit all the safety stuff and some cloths, rain coat and a real lunch too. So my wife's birthday was coming up and she needed a new pack since we are hiking more now that we moved to Kentucky near the Red River Gorge. I surprised her with one. She loves it. Fits her perfectly at 5ft4in and 130lbs. Our only gripe is that the mouth piece cover is extra...we bouhgt 2 but feel they should be included at the price. Also for hiking in 90deg weather I wrapped my water bladder in closed cell foam sheathing. It worked cold water all day, don't see that will be needed in the spring or fall. Thanks fir for a grest product and excellent customer service!!!

Your back will thank you for buying this pack!

This pack is the best one I've ever owned! It fits me perfectly and distributes weight perfectly across my shoulders and hips. I love that the fit is so customizable! Plus, the 2-liter hydration bladder and lots of pockets and compartment space mean I can easily carry everything I need for a long day hike. Can't wait to hit the trails again in September!

Weird fit

I purchased the Juno 24 hydro. The hard frame for the back of pack extends about 4 inches above the shoulder straps. It bumps into the back of my head above the neck. I’ve never seen anything like this before. See photos. I have 2 other Gregory packs and really liked them. I’m very disappointed in this new pack
