Description
Eleven litres is the size that gets carried. Big enough for a jacket, a lunch and the bladder; small enough that you stop noticing it by the second mile. This hydration backpack from Fox Outdoor ships with a 2.5 litre bladder already in it, so there is nothing else to buy.
What a hydration backpack is actually for
The bladder sits in its own back-panel pocket and the hose comes out through one of two concealed ports on the shoulder straps, left or right. You drink without stopping and without taking the pack off. The back panel is “stay-cool” mesh, which is the difference between a damp shirt and a soaked one on a warm day.
Features
- 2.5 L hydration bladder included. Dedicated back-panel pocket, dual hose ports concealed on the straps.
- 11 L / 680 cu in capacity across one main compartment and a front pocket with internal mesh organisers.
- 600 denier heavy-weight fabric — the hard-wearing end of pack material, not a summer daypack shell.
- Modular attachment points on the front face for adding pouches.
- Loop panels for ID and patches, plus a matching Fox patch in the box.
- Top carrying handle and adjustable padded shoulder straps.

Where a hydration backpack like this fits
Day hikes, trail rides, range days, long walks with a dog. It is the hydration backpack you leave by the door with the bladder empty and fill on the way out. Browse the rest of our outdoor gear or the whole MAXELTI Active shop.
Care
Empty and dry the bladder after every use, hanging it open — that single habit is what stops the taste going stale. Wash the pack by hand and air-dry it. Hydration matters more than most people plan for; the CDC guidance on water and healthy drinks is a two-minute read.
Frequently asked questions
Does it come with the bladder?
Yes. A 2.5 litre bladder is included, in its own back-panel pocket.
Which side does the hose come out?
Either. There are two concealed ports, one on each shoulder strap.
Is 11 litres enough for a full day?
For a day hike, yes: water, a layer, food and the small things. It is not an overnight pack.
Which colours can I actually get?
Black and Shadow Grey. We only list colours the warehouse has, so what you see is what ships.
