I just bought a Helly Hansen mid layer. It's warm as I tried to wear it on the plane under my shell and I almost died. Cost was about $63 US as it was on sale at the HH store in Banff. I also just bought a patagonia nano puff for $100. I'll see how it goes with these 2 and which I like better. I'm frugal and always look for bargains. Can we say eBay daily searches
. I had won an eBay auction for an Arc'teryx Atom LT but then the seller canceled the sale so I was bummed. I'll see how it goes this season. I'm keeping an eye out for a Patagonia Nano Air or a Thermo ball for a lighter layer for warmer temps.
