This extremely good product: good for 20 hours,
I love that they keep me nice and warm when I go do some winter sports, I put some in each boot, and one pack in each glove.
You can dispose of them easily.
Their convenient to take with you when camping.
Are you kidding me? Of course I would repurchase this product.
A product that keeps one that warm for that long of duration of time, is worth getting.
