Gregory Inertia 15 H2O Hydration Pack - Men's

There's a loop with a bungee tie off for throwing your poles on the outside. The pack also has side compression straps to secure your gear if you don'...

I like this pack in every aspects except the mesh padding does not provide significant back ventilation. Even in a snow storm with the ambient temperature in the teens. I still sweat through my gear, making for a very cold change of clothing. Still searching for the ultimate back ventilation in a fr...

Good size, nice H20 bladder (included!), good adjustments. Lacks trekking pole loops of bigger Inertia models. Small pocket is padded and has key clip, but larger pocket with dividers, organizers (e.g. inner pockets, zipped mesh pocket) would have made a perfect commuter day pack PLUS day hiker/hydr...

The wife and I are getting more serious about hiking and the outdoors and we wanted a bacpack that had a reservoir and could carry our food and essentials for the day. The inertia15 and swift 15 are perfect for our day trips. They're light, fit naturally and don't become a bother even after a full d...

I like the backpack and it’s versatility. One side of the right strap was rubbing...something wasn’t symmetrical. Two days after I started using it, one of the seams in a pocket came undone. Very disappointed in the quality. Furthermore, disappointed in REI for not replacing it and just forced a ref...

Would be nice to have a "quick release" of the hose at the bottom of the bladder. Why? When removing the bladder to clean and/ or hang dry, the hose must be removed with the bladder. Which means each time the hose must be taken through the should straps/ clips and then put back again, and again.

I loved the backpack. Well crafted, sturdy and very stylish. My only complaint is that the water reservoir does not Quick Disconnect.

I'm not one to write a rave review. BUT, I got this backpack for my husband for our trip out of the country, his first time. I'm an avid adventurer but this is his first serious backpack. To be clear, of all the top of the line backpacks, I definitely chose this one because it says Gregory on it whi...

The inertia 15 was exactly what I was looking for when it comes to a small commuter bag or day pack! For me, I’m constantly on the go, and the inertia 15 that proven itself a perfect pack for biking, short hikes or just a small bag to take to the gym. I love that it comes with a great 3L water bladd...

I had high hopes for this bag but wasn't impressed. The bag does include a 3L reservoir which is great but the alleged "breathable back panel" didn't ventilate any better than other bags I've owned, the one small, plush-lined pocket doesn't have any dividers so anything you place in there will move ...
