CamelBak’s revolutionary idea to create on-the-go hydration was grounded in access, efficiency and speed. Those same values govern the design of the Octane 25, its new hydration backpack that blends elements of hiking daypacks with those of trail running vests in a design that’ll keep you covering ground… fast.
What We Like
XL Shoulder Straps
Shoulder straps define the form of a backpack, but they’re also frequently underutilized. The Octane’s, however, are not; they come loaded with six pockets, an emergency whistle, two chest straps and a holster for a hydration tube. There’s enough access to keep all the essentials up-front and at hand.

Comfy Ultralight Mesh
Mesh can be rigid; it can be scratchy. CamelBak used a soft type in the shoulder straps, so your skin can handle speed hiking in a sleeveless shirt.
So. Many. Sleeves.
There are three drop-in, sleeve-style pockets on the outside of the Octane’s main body. There are five on the shoulder straps. There are seven inside the main compartment. These kinds of pockets are great for stashing things quickly — like a layer removed midway up a mountain — and securely. They’re also great for those of us who are OCD about pack organization.
Understated Feature: It Opens Wide
CamelBak could’ve saved a few more grams by shortening the zipper that provides access to the main compartment. The company even could’ve argued that, with a pack this size, you don’t need wide-angle access to everything inside. But having the ability to unzip the compartment for a full view of everything is great, especially if you’ve stuffed your rain jacket at the bottom.
Watch Out For
This Isn’t a City-to-Mountain Backpack
It’s a technical mountain pack, a specialist. Sure, you could throw your laptop into the compartment where the hydration bladder hangs (if it’s a 13-inch or smaller), and you could stash keys, chargers and other daily tools in its many pockets. But the Octane won’t hold and protect these items the way other, everyday-oriented packs will.
