The large size is cut for the big muscle groups - thighs, quads and hamstrings - where an ice pack held on by hand slides off the moment you shift position. The sleeve wraps the whole limb and stays where you put it.
Inside it sits a reusable gel insert that does both jobs. Three to four hours in the freezer and it runs cold; 15 to 30 seconds in the microwave and it runs warm. Cold after a hard leg session, warmth before mobility work - the same sleeve covers both ends of the routine.
The fabric conforms to the shape of the leg and applies light compression, with fasteners to adjust how firmly it sits. Sessions run around 15 to 20 minutes, and it comes off if anything becomes uncomfortable. Never put extreme heat or cold straight onto bare skin.
The shell is durable and built for repeated freeze and heat cycles, and the gel core is sealed to reduce the chance of leaking. The outer fabric wipes clean rather than needing a wash each time, which is what makes it practical to keep in a gym bag.
Directions
For cold therapy: place the gel pack in the freezer for at least 3-4 hours (or as per the instructions). For heat therapy: microwave the gel pack for 15-30 seconds (or follow provided guidelines). Insert the gel pack into the sleeve. Slide the sleeve over the treatment area. Adjust compression straps for a snug but comfortable fit. Limit session to approximately 15-20 minutes (or as recommended). Remove if discomfort arises.
Storage
Store gel pack and sleeve in a cool, dry place. Avoid prolonged exposure to direct sunlight or heat. Do not puncture gel pack.
Warnings
Do not apply extreme heat or cold directly to bare skin. Use caution if you have circulatory, neurological, or skin conditions. Not intended to replace medical treatment. Discontinue use if skin irritation or discomfort occurs. Always follow the heating and cooling instructions precisely.
