Introducing: double-O-bag.

A new innivative srat post bag, designed for bicycle riders by a bicycle rider. 

After many years as a mountain bike rider, and since I could not find an optimal solution for easy carrying accessing of my stuff, I decided to design one myself.

Allowing quick removal in replacing, the double-O-bag is the most comfortable seat post back you've ever tried!

Thnks to this feature, you can use the same bag with more than one bicycle pair, so all the things you need follow you wherver you go.

Use it with your commuting bike, Take it with you. No one will ever steal your stuff

The double-O-bag is like a doctor's bag. It has a long ziiper so you can access all its content easily. It also had a grip nadle so you can carry it anywhere with comfort

double-O-bag comes with you. To whereever you may need it.

It's large enough to carry all the emergency gear you may need and an MTB innver tube and a snack.
