Carry Capacity

Because of the varying structural characteristics of the bags, physical dimensions do not sufficiently indicate the carrying capacity of the bag sizes. Each bag stretches, but to varying extents and in different ways. The best means of choosing a bag according to your carrying needs is to look at the photos demonstrating capabilities you can expect from each size. As a base line, the medium bag will hold 4 2-litre containers of beverages (as they are commonly sold in North America).
