Storage and carry points

A lightweight 18L hydration backpack with a 2L bladder, insulated back section, splash-proof fabric and a removable rain cover.

This RAINSMORE hydration backpack is built around hands-free drinking and compact carry space for active days outdoors. It comes with a 2L hydration bladder and an 18L pack that can hold clothes and other essentials, with extra storage kept simple and accessible.

The backpack uses high quality polyester fabric with reinforced stitching, and the back panel is made from soft, breathable material to help keep things more comfortable during longer periods of wear. The back section is also insulated to help keep water cold for longer, while the bladder is held in place with two internal safety buckles.

  • Two side mesh pockets for bottles or umbrellas
  • Two front zip pockets for outdoor essentials
  • A removable pocket for a mobile phone and sunglasses
  • A buckle design for securing a helmet
  • External elastic cord and trekking pole loops for carrying extra gear outside

Built for changing weather and low light

The fabric is splash-proof for light rain, and a removable rain cover is included for heavier weather. The cover stores in a hidden bottom pocket when not needed. Reflective straps on the front and back add visibility, and an inside removable reflective strip keychain helps with finding items in the dark.

Hydration details

Quick-access hose connections on both the left and right shoulder straps make it easier to drink while riding or hiking. The external chest strap includes an emergency survival whistle, which adds a practical extra for outdoor use.

This is a compact hydration backpack rather than a large rucksack, so it suits shorter hikes, cycling, running, biking and similar activities where easy access to water matters more than carrying bulky kit.
