One plus one is a product that combines a bicycle saddle with a tent to provide cyclists with greater mobility and a place to sleep if they need one. Carried in a backpack on the bike, the tent can be unpacked and set up quickly and easily. There is an air mattress built right in to provide for a more comfortable nights sleep. The upper and lower parts of the tent are connected with a zipper, which is removable and easy to replace in this modular design. One plus one reflects a new attitude towards more flexible living.
