Every mile has a story

One hydration vest in two capacities: the 5 L is a slim, minimal running vest that vanishes at pace; the 6 L is a slightly larger, more structured pack with a padded mesh back and a stretch chest phone pocket for the days you carry more. Both take soft flasks up front and a 1.5 L bladder at the back — cut for an Indian frame and tested across dry-tap city loops, dawn road long runs and monsoon Ghats.

Questions
Pick the 5 L if you want the least vest that still carries water — it is slim, minimal, and disappears at pace on road long runs and races. Pick the 6 L if you carry more: it is a touch larger and more structured, with a padded mesh back for comfort under load and a stretch chest pocket sized for a phone. Both hold the same flasks and the same bladder.
Same DNA — soft-flask front pockets, 1.5 L bladder sleeve, reflective detail, adjustable sternum and waist, YKK zip. The 6 L adds about a litre of carry, a padded mesh back panel, and a stretch chest phone pocket. The 5 L keeps it stripped and light.
Yes — both sizes. The back sleeve takes the STRX 1.5 L Hydration Bladder and most standard reservoirs up to 1.5 litres. Flasks up front, bladder at the back, or run either alone.
The vest, in the size and colour you choose. Soft flasks and the bladder are sold separately — most runners already own flasks, and we would rather not charge you for a second set.
