Lifting a 40-litre Aquaroll into a storage bag is no fun, especially when it contains 90lb of water. But now you can wrap a cover around it to protect it from the elements.

The insulated Aqua Cover comprises a 20mm-thick layer of foam insulation sandwiched between a PVC-coated nylon shell and a thermal-coated nylon lining to prevent freezing in winter. Best of all, it’s reversible: put the thermal coating outside in summer to keep water cool. It has a full-length Velcro fastener and a separate insulated base.
