Question: Is this item filled with water or gel?
Document: I got this for my son who is a pitcher for his travel team. The wrap works well in covering the areas of his shoulder and arm that are sore and is easily adjustable. I was expecting gel packs, but the inserts are water/ice. which seems to stay colder longer than the gel pacs. Since the ice is held in place by mesh, it can be too cold on bare skin, but is good through a t-shirt.
This item is perfect for icing you shoulder and elbow at the same time. I ordered an extra set of the ice packs. The item is well constructed.
My son (19yr) pitches for D2 & summer league. He uses it after the games & says it works really well. A lot better than dripping ice water everywhere.
I received the shoulder pack sooner than expected.I immediately put it in the freezer. After my 12 year olds baseball game in which he pitched I put it on.It was comfortable and fit as expected.It seemed to stay cold for at least an hour.I also was able to use this on my husbands arm. Overall a great item and would recommend.
I get plenty of use out of this and it has worked great for me! I love how long it stays cold rather than those gel packs! I would highly recommend this to any pitchers or even position players!
Trying to conform it to my shoulder was futile. It's very brittle and was kind of like trying to wrap a cardboard box around my shoulder. Arm part was ok but still not very conforming. Gel is going to be the better way to go.
The ice packs need to be replaced with the gel packs, the ice packs don't conform or mold to your shoulder very well when they are frozen. It takes a while before they melt, which is good, but not conforming to the shoulder means you are not getting the cold in all the places you need it.
I've had this product for about six months now. Although it seems somewhat flimsy, it's well designed and it has worked reasonably well.However, the problem lies in the ice inserts. They consist of (frozen) water trapped in thin plastic compartments--think of small, connected, plastic-wrapped icicles.
So far I've lost nine small ice-pockets. That's a sizable reduction in effectiveness.Replacement inserts cost $25 with shipping included. So I am getting to the point when I need to decide whether I am willing to spend $25 every six months for "ice maintenance", or whether I should try a gel-based alternative. That's something to think about, if you are considering buying this product.
wonderful product! with 2 pitchers in the house we are going to purchase another. allows them to keep moving and going while icing the arm and covers all the important areas
