HyperIce® Fuel are reusable synthetic ice crystals that are non-toxic and biodegradable. These crystals are used in conjunction with the HyperIce Ice Compression Device system as an alternative to real ice. Fuel cooling ice crystals mimic real ice nuggets in shape and size and maintain optimal freezer temperatures through the full icing cycle. These alternative ice crystals are pliable as well and form an “ice cast” around the targeted body part to reduce swelling from all angles.This portable bottle of crystals screws directly into the Ice Cell cap to deliver long-lasting cooling power for effective cold compression therapy treatment. Toss into your training bag to help members and athletes receive immediate cold compression therapy whether in your gym or on the road.
