CamelBak Cloud Walker 18
#13 — Best Hydration Daypack

CamelBak Cloud Walker 18 Review (2026)

A 2.5L reservoir included, and a pack built around drinking on the move

★★★★★
8.1/10
Reviewed by William • Updated August 2026 $75

Most packs have a reservoir sleeve; this one includes the reservoir, and CamelBak's Crux is the best in the category. The bite valve flows well, the fill port is wide enough to clean, and the magnetic tube retention keeps the hose where you left it. As a pack the Cloud Walker is unremarkable — 18 liters, light padding, modest organization — but the bundled reservoir means the total cost of a hydration setup is $75 rather than $110 or more.

What Sets It Apart

Reservoirs mean people drink more, which is the actual health outcome that matters on a hot day. Reaching for a bottle requires a decision and a small effort; a hose requires neither. If you have ever finished a summer hike with a headache and a mostly full water bottle, this is the pack that fixes it.

Common Questions

Reservoir or bottles?
Reservoirs win on how much you actually drink; bottles win on ease of cleaning, refilling at a source, and knowing how much you have left. Many hikers carry both.
How do I keep the reservoir from getting moldy?
Empty and dry it fully after every trip, store it in the freezer between uses, and avoid putting anything but water in it.
