Oakley: Hands down the best optics around. Expensive, but worth every penny.
NUUN: Easy and super convenent. Low sugar and good taste.
PEARL IZUMI OPTIK JACKET: Sickest light jacket ever. Packs super small (fits in jersey pocket with room) great protection...not sure how i trained without this thing. Killer.
So those are my picks of the 5 best products for 2010. After using all these extensively I can honestly say these are products i would go spend my hard earned money on! Some of these things i got for free or discounted, some of them i go and pay full retail for.
