The Nike Tech Helios Sun is a nice jacket. It's very light weight and airy. It definitely had me looking fly on my way to the gym. If you're looking for something to keep you warm this isn't it, this is something you just throw on real quick when the weather is already nice or if you're doing an early morning run/work out in spring/summer weather. The thumb holes are a nice touch. The jacket can zip up all the way up to your nose with holes to breathe but that really isn't comfortable. The hood has a nice brim that fits well over hats. One thing I didn't like is the pockets there is no way to secure your items and they just bounce around in the pocket and can fall out. The jacket gets the job done, has you looking great while also aiding in your work outs.
