I deliberately left a hooded sweatshirt at work today as part of my incremental kit building strategy. I do have a spare fleece jacket -- I'll swap them out next time I go in.

Fleece pants are tougher, as I don't own any. I'll cast about and see if I can find some that aren't too expensive. What I'd like to do is bite the bullet and buy another set of UA Charged Cotton Storm sweats -- that stuff is amazingly comfy, warm, and it sheds water like you wouldn't believe.
