Your go-to seat pack. The Trek Saddle Bag installs in seconds and stays put, whether you are commuting through a wet Fife winter or out on the road all day. The XL is the biggest in the range at 2 litres — enough for a tube, levers, multitool, CO2 and still room for a phone and keys.

The main fabric is a PFC-free durable water repellent, made entirely from recycled polyester, and the chunky YKK waterproof zip is easy to work one-handed or in gloves.
