Product ID: 1014853

The ORTLIEB 16.5 litre Seat Pack sits neatly out of the way behind the saddle, yet can carry a surprisingly large amount of cargo.

The simple yet secure attachment system and side compression straps hold it firm even when fully laden, and thanks to the waterproof roll closure its capacity can be reduced down to eight litres if required so the contents are always held firmly in place.

Ortlieb Seat Pack - 16.5L

For those going a little further afield the ORTLIEB 16.5 litre Seat Pack provides extra carrying capacity in a convenient and stable under saddle format. The tough fabric is both waterproof and lightweight, whilst the zip-free roll closure and side compression straps enable the capacity to be adjusted from 16.5 litres down to eight litres if required. The useful air release valve enables excess air to be purged once the bag is sealed shut in order to reduce bulk.
