BICAREE Ice Pack for Injuries Reusable, Ice Bags Hot Water Bag for Hot & Cold Therapy and Pain Relief with Cover, No-Leak Elastic Breathable Ice Bag, Size 11", Blue

It definitely keeps hot and cold. I love how it forms to the area that needs the treatment, better than ice packs that have to be frozen in the freezer. 100% recommend this product

Just like the old days a real ice pack. Lasts a long time a must for any sports family or just a must. I tried so many other ice packs what a waste of money, this is amazing.

I purchased the product initially being so excited. It worked beautifully about the 30th time I used it( around the 60 day mark) it started to leak. The minute the ice starts to melt it leaks through the fabric not the cap. Needless to say I was super disappointed.

It's made of good quality materials and completely leak proof. I have even dropped it and it remained fully sealed. The heat transfer is also smooth and we can easily grab it from the cap.

Used as an ice pack for my swollen foot. Hasn’t leaked in a week of heavy use. So far so good.
