Hi – I'm pretty sure I'm going to purchase one of the Montbell U.L. Spiral Down Huggers (http://www.montbell.us/products/list.php?cat_id=795).
My question is, should I get the #3(30F), or the #1(15F)?
My trips will be in the Canadian Rockies from June to September, sleeping in a tarptent. I'll also be carrying a Thermawrap jacket in case I need extra warmth. Or would I extend the range of the bag by adding the spiral down thermal sheet (50F).
Thanks for the help.
Aaron
