I'm working on relocating somewhere cooler - so I'll keep the wool jammies in mind when that happens.
OMG, and #4 is awesome! Thanks for bringing it to my attention (and for posting it originally).
I'd also like to mention that wool has given me a winter riding partner again. My husband (the furnace) is a cold weather wimp. A true southern boy! I bought him two smartwool tops last year and not only did he never wear them, but he hardly ever rode with me. I thought I'd be riding alone again this winter, but last weekend he pulled out the wool and he's convinced! He loved it and it's inspiring him to try colder temps with me! Yay for wool!!
