The CoreCooling products have been tested by me during my preparation for the IM world championships at Kona. They work very well. For me using ice in the pockets would be the best option, because we have to hand in our T1-T2 bag already a full day ahead.

My plan was to use the base layer and put it on during swimming. I tested that and that worked perfectly. I wanted to put on the arm-sleeves and head-band in T2, to use them during running. To my great agony I forgot to take the base-layer with me on race-morning from home...

I could use the head-band and arm-sleeves during the race. Putting the ice in the pockets worked very well, especially since I took ice-cubes in a cup from aid stations and then put the ice-cubes in the pockets one by one during running.

The good thing about the CoreCooling is that I did not notice it during the race. I mean, you just do not notice any hinder. Just the coolness.

The CoreCooling just works, easy as that. I will implement it in my cooling strategy for races. And also use it during my indoor trainings in winter, it will help me to train with more quality and to recover faster.
