Well, it looks like you want a response and it doesn’t seem the BPL community is being much of a help. Course, it is Super Bowl Sunday, so I’ll give it my non-solicited watching football response. You and I share similar equipment, but I don’t know where you’re going or what temperatures you'll encounter, so I might be off with my comments:
Do you need the down pants? I’ve found I can wear just SmartWool long underwear just fine into the 30’s and possibly lower. Insulated pants are really for below freezing.
Do you need the full net bivy? In many places, bugs just won’t be a problem, and if they are, a headnet would be lighter. Most bug bivy’s are too restrictive anyway.
Do you need two pads? Talk with GG and they’ll tell you that Glen uses his single pad down to fairly low temperatures. Having given it a shot myself, I’d agree.
Do you need sunglasses? If you are somewhere other than dense forests, you’ll need them, so I’m just throwing this out there.
Nice list though.
