I would not consider my self an athlete by any means (although I do go to the gym regularly) and I never had to use such product before so up to a few days ago I did not even know this product existed (in this form) and now that I "discovered" it, I made sure that I have it near by in case I need it. Here is my experience.A week ago I was at a steel shooting competition and it was a day long event on a hot and humid day. Towards the end of the day, my hands felt sticky from the humidity and too slippery to grip the pistol so almost after every shot I had to re-grip the pistol because the recoil would move it in my palms. These competitions are usually out in the middle of nowhere and although we have plenty of stuff to drink, there is no water to wash our hands. I tried cleaning them with purell but that did not do much about my problem. Then I complaint about it to what appears to be the right person who pulled out this rosin bag from his pocket and said to just "slap this in your palms a couple of times". What an immediate effect!!! The powder covered my palms just a bit and although I can see some of the dust in my palms, it did not feel like it was too much but when I gave him back the bag and rubbed my palms together, my hands felt totally dry. Perhaps the feeling was amplified by the long humid day but my hands felt like I washed them and dried them. I was able to grip the pistol just fine and recoil did not change my grip. I kept using the bag every time it was my turn to shoot.Needless to say that I ordered a bag and dropped it in my range bag. It is the perfect form of dispenser for my needs. It will not make a mess in my bag and will not make a mess around me when I use it because it dispenses the right amount of rosin. I am not sure it would work to an acceptable degree for athletes but the cost is minimal and it is worth having it around.
