Get in a sporty frame of mind using Adidas by Stella McCartney's dark-grey tote bag. Stow your mat in the zip-fastening waterproof base compartment and pack all other kit in the main internal compartment. A mesh pocket allows you to separate smaller items, while the long top zip makes it easy to organise everything. The two top handles are the right length to allow it to be carried by hand or slung over one shoulder.
