Tarn Hydration Pack features

Fit and comfort

Soft and padded, wicking air-mesh backing fabric and shoulder straps give extra comfort during wear. The air flow channels on the back help control temperature and reduce sweat build up.

Fully adjustable shoulder, chest and waist fastening straps give a more personalised fit. Velcro loops secure the bladder in place within the pack to ensure complete comfort both at the beginning and the end of your activity.


It has a 1.5 litre bladder included with the pack. Features a newly designed bladder which has a large opening for easy filling and cleaning. The soft bite valve is easy to use on the go and comes with a secure on/off tap which is really effective against leaking when not in use.

The bladder is secured in place within the pack to reduce movement whilst you’re on the go.

Additional features

Larger, single finger zipper loops are quick and easy to use.  Headphone port provides secure and protected cable access to the inner stash pocket which is the perfect size to hold your devices.

Reflective details give added safety during low level light conditions.  Made from a durable 6000 Durable rip stop nylon for long lasting use.
