Thank you everyone for the recommendations.
I actually do own a few pairs of PI socks, but haven't experimented yet to figure out what I like best (yes, I typically just wear these socks as every day sort of socks because I think they are cute). I haven't tried wool yet but will definitely need to try some out. I also have a camelback water bottle/pack that I have used before, and I like it.
I think the hardest part will be figuring out the shorts and tights...so we'll see what I can find out there.
Thanks again!
