We compared two running hydration vests: the TSJyrinth Running Hydration Vest Backpack and the UTOBEST Running Vest Lightweight Hydration Pack.
What we looked at
Storage capacity, included accessories, and price.
The verdict
If you want the lower price on a complete set with a 2L bladder and 500ml soft flask included, the TSJyrinth is the value pick at £18.99, though only 7 were left in stock when checked. If you would rather pay £21.00 more for a roomier 10L vest with 7 pockets, YKK zippers and a safety whistle, the UTOBEST is the alternative, at £39.99.

An £18.99 hydration vest with a 2L bladder and 500ml flask included; only 7 left in stock when checked.

A £39.99 hydration vest with 10L capacity across 7 pockets.
