I've had basic first aid training through the Red Cross and Army, and I completed the CLS course while on the NG. But, that was almost 20 years ago, so my quandry is how to use the new products, like QuikClot. I have seen the YouTube vids, and read as much as I can, but what QuikClot product to buy? One 50g 'Trauma' sponge, or 2 25g 'Sport' sponge, or the 'Combat Gauze'? I can't seem to find anything telling me the difference. Is 2 25g equal to one 50g? Is 2 50g equal to one roll of the gauze?

The IFAK is indeed basic, but there is little on the web about training/use the components, and for what situation. When I was in, you were issued one field dressing, and the only treatment for blood loss was pressure.
