Gregory

Endo 15L Hydration Backpack

It’s the perfect size for any day trip hiking, climbing, or cycling.

Perfect hydration pack for mountain biking

My experience with the Gregory Endo 15 H20 for mountain biking has been excellent. The pockets are well thought out, the hydration pack sloshes a lot less than others, and does not create any weird chemical taste as some other hydration packs have.

good bike pack

lightweight, comfortable, plenty of storage for a longer ride including bikepacking (with the usual assortment of bicycle packs), wish the hip belt pockets were larger though

Nice Bag/Pockets rip

I love the bag - nice number of pockets and zippers. Fits really nicely on me. But I am bummed that the inner pockets have already torn. Material on inside pockets very thin. Used for hiking and day trips to the beach/river. It's lightweight which is also great.

Pretty stoked on this bag. Even with its 3L reservoir full and the bag full of kit for a long day the pack remains very, very comfortable. Moreover, breathability is pretty good. No complaints so far. There are obviously more minimal options out there, but the pack does such a good job distributing weight I prefer it to other hydration solutions I've tried.

Well designed aqua pack.

Love the suspension system. Very comfortable. Roomy- handles all my gear for a day on the trails. Like it way better than the Camelback I previously had. I’d say it’s about the same quality as my Osprey.

Great bike backpack!

Excellent ventilation, and plenty of storage space, with enough space to store everything you need! I wish the blader had a slide top to make cleaning easier, but I already had a blader I wanted to use with it anyway, so that didn't bother me.

Gregory Endo long-term review

I’ve been using this backpack for 6 months for mountain biking mostly and hiking occasionally. The backpack is lightweight, but it’s made with a tough material. The back mesh-panel keeps a steady air flow during a ride preventing my tshirt from getting soaked. The internal pockets are great for organizing snacks, tools, and keys. My favorite things are the hip pockets and the sunglasses cord. One thing that could get better was the hose. It’s not that long, and it kept unattached itself from the magnetic clip. I had to buy the extension kit. Overall, I have made a good decision purchasing Gregory Endo!

Great MTB pack

This pack is a great size for short to medium-length rides in any terrain. Its many pockets and dedicated tool pouch are awesome for keeping things organized. I've also used this bag for nordic skiing, where it works equally well. The strap adjustments work well. The only thing that I would improve upon is the magnet-secured water hose, which sometimes falls down in rough terrain. Other than that, this is an excellent pack.

Small but Spacious-Convenient and Comfortable!

Admittedly, I am a Gregory fan, owning numerous models for varied applications. The Endo 15 is a perfect MTB/Gravel grinding size, fitting everything I need and then some for short and extended daily forays. I have no complaints and have even “endo’d” while wearing it...without damage to the pack. I did have a bug repellent bottle leak which degraded the waterproof coating on the inside...mental lapse. It is my daily use pack for all excursions and if I don’t keep it close my daughter snags it.
