We test the Profile Design Sync Hydration System.

Profile Design Sync Hydration System

Carrying water is a pain on long, slow summer runs so this bottle belt could be useful if you’re in training for an Ironman this year.

With the two 235ml bottles full, it weighs just over 600g but because the weight is carried on your hips, you won’t notice it and it’s certainly more comfortable than carrying a half-litre bottle in one hand for a three-hour run. The bottle holders can be moved anywhere round the belt and are backed with soft non-slip pads.

Our size medium (34”) came up quite small but there is some stretch in the belt, and its snug fit and strong Velcro fastening meant that it didn’t budge an inch even when full. The small, flattened bottles keep it much more stable than other hydration belts we’ve tried.
The bottles are easy to remove and put back on the run, although we found the ‘non-leak caps’ didn’t quite live up to their name if you squeeze the bottle at the same time as drinking. A bigger irritation was that we kept hitting our arms on the bottles with the belt round the waist, so you might want to buy big enough so that the belt can sit lower down on your hips. It would also benefit from a couple of extra pockets or loops for gels and keys.

Useful water storage for long runs but buy a size up.
