Ditch the sleeping bag…extra layers instead???

Aw yeah, here in Maine  I’ve been sleeping in just 3-4 layers- a Torrid puffy with hood, Houdini wind shirt, long sleeve lightweight shirt on top, lightweight long johns and wind pants on bottom into the low 50s. I like the feeling of not being “half in the bag” :) also in a superlight bivy i use a neoair xlite inflatable.

for sure doable especially if you have a pair of regular pants or shorts, warm pad, hat, gloves, etc… I’ve been using my booties as well, socks would be fine probably. Maybe bring Mylar emergency blanket? I use one for a ground sheet

I’d call that a definite maybe … provided that the weather forecasts are reliable.

How warm do you sleep?
The bivvy will help
May not matter too much but what weight fabric in the long johns?
Is the MB exlite the hooded anorak they currently sell?  the hood will be a key part of success.
I’d include a pair of wool socks and light wt gloves … cold fingers and toes keep me awake

July well below the rim in greater Grand Canyon will be hot. NWS forecast for Havasupai canyon:

Highs above 100 F, lows in the 80s. Not the same weather as Supai at higher elevation.

I’d take a cotton sheet.

Rex, would you wear the cotton sheet toga  style with sandals? Probably a chrome dome umbrella would top off that look with style and grace and sun protection. Effective way to scare/intrigue tourists ;-)

And have a great trip Matt!
