Ok so i picked up and HPG Serape last May and used it as my primary sleeping bag all throughout summer and into the fall in the Sierra between 7-8000ft.
Mostly in the Mid 40's at night, but i did test out its insulation with nothing else but shorts and Tshirt on my pad down to 38f, it was chilly but i didn't Die lol.
As hunting season started in I augmented it with my fleece jacket and USGI woobie and stayed pretty comfy. For me the Serape's limit seems to be close to freezing.
So as im gearing up all winter long, and getting warmer clothing to extend my stay in the back country i catch myself looking at a 20F synthetic bag at REI (5lbs but super wide and long), however I'm also trying to pick up gear for my SO and was looking at bags for her too (womens 25f bag 2.5lbs). Then i remembered a thread about being able to zip two Serapes together for Snuggly-Fun! I'm not super fond of the confines of a mummy bag and the Serape has done the job remarkably well.
So here's what i'm thinking is when me and the SO are backpacking together we each carry a serape at 2.5lbs a piece, Zip together for a mega-serape snuggle session! and When i'm rolling with my hunting buddy and no SO and the snow kicks in i carry both serapes (5lbs) and Double up the insulation like a Double Serape Taco ! This is only a temporary solution until i save up for a nice wide 20 deg bag (western mountaineering or Kifaru Slick Wide/long). the other advantage is i already have a serape in Ranger green and you know you can't have two pieces of gear, the same color occupying the same space (something about disrupting the space-time continuum)so it gives me an excuse to buy in multi-cam! yay!
-Double wide snuggle bag for the GF
-double thick insulation for winter, (until i get a propper bag)
only con i can think of is carry both serapes myself at 5lbs, but its also the same weight as the 20f REI bag I was looking at
So what do you guys think? can 2xserapes get me into the 20's , if 1 serape +fleece+pad+BDUpants can already get me to 32f?
