A holdall, or gym bag in the US, is a large bag made of cloth or leather typically with a rectangular base and a zippered opening at the top. Two handles enable the bag to be carried, and a strap (often optional) lets the user support the bag on the shoulders.
It is often used to carry luggage or sports equipment, and has the advantage over the suitcase of being compressible when empty.

It is a flat, rectangular, canvas bag, when unravelled. Once filled, it is rolled like a sleeping bag and held together with straps.
