Fit the basic and extra items

I can fit 700x25c lube, multitool 500 compact, 3 compact tyre levers, puncture kit, sunscreen in small tube (yes, sunscreen :)), some band-aids, house keys (7 keys :)) and ATM card to this saddle bag. And, there is still space to put something thin or small. The velcro works as a charm (too early to say how long will it last.). Sits perfectly under the sandle and doesn't look bulky (perhaps, this is subjective). Highly recommended if you like to bring everything when cycling.

Saddle bag

Well made bag, much less expensive than similar bags at other stores. Fits easily under saddle. Mine holds a spare tube, multi-tool, CO2 cartridge and applicator, patch kit, tire levers and some money, everything I need while on the road.
