Hey so I am starting a trail maintenance job soon and I have a few questions about layering. right now I have a few nice pieces, a mountain hardwear shell and the Atom LT. I am not going to be taking my MH shell with and I will use a patagonia torrent. However I was wondering what I should do for a mid layer? So I have the Atom LT and an R2. should i take the LT with... but I like it so much i don't want to ruin it doing trail maintenance. I was thinking about buying a patagonia nano puff... do you think that would be a good idea? If you have any advice let me know. I get some pro deals now and id like to take advantage of them while they last. Also I will be working up in montana... it gets cold at night

Thanks
