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.

Good size

Small to look at, but can pack a lot of stuff into it.

I had a Decathlon saddle bag that lasted years. Purchased this about 5 months ago and just had to throw it away as the Velcro strap has torn through where it attaches to the saddle rails. What I have subsequently noticed is that the previous one used a thick webbing which could cope with the wear and tear. I would not recommend purchasing this item based on this.

Hello there. Thank you for the feedback about the webbing on the strap of the saddle bag. It has been passed on to the relevant Product Managers for review. You have a two year guarantee on Decathlon branded products for exchange or return with proof of purchase so don't hesitate to go back to your nearest store with the faulty item.
