Ice Packs

Like a bag of frozen peas that's been to finishing school. These flexible gel packs are divided into cells, so they bend and mould round a knee, shoulder, ankle or back instead of sitting there like a frozen brick. Freeze them, wrap them in a cloth or cover, and use them to help soothe aches, bumps and swelling after injury or exercise. The 1-cell and 3-cell are the compact ones for smaller joints, and the 5-cell is the bigger one for wider areas. Reusable, so there's no need to sacrifice another bag of peas to the cause.
