A friend and I are thru-hiking the OHT starting this Sunday (Dec 14).
I have little winter experience. My previous winter trips were spent in the desert of Big Bend where it usually does not dip below 25* at night.
The weather forecast for nearby Fayetteville, AR shows lows as low as 20* for the beginning of our trek. It will be colder on the trail. The extreme low for the month of December is -12*.
Bag: WM Summerlite
Shelter: Hubba Hubba (sharing the tent)
Pad: Ridgerest (Do I need to supplement this as well?)
Clothing:
– Patagonia Capilene 1 Top & Bottoms
– Arcteryx Delta LT Zip (Lightweight fleece)
– Montbell UL Wind Jacket
– Cocoon Pullover
– ID PLQ Pants
– DriDucks rain gear (last resort)
– MH Butter Balaclava
– Wool watch cap
– Teko wool 1/4 socks
I am 5'8" 140 lbs with a high metabolism and low body fat.
I consider myself an average sleeper. I have taken a stock Summerlite down to the rating with just a base layer and a beanie without the need to zip it up and cinch it down.
I will go to bed well fed. I will shift a lot of the down from the bottom of the bag to the top. I will be wearing everything but the DriDucks to bed. We will be maxing out the mileage, so I will be exhausted at the end of each day.
I am confident I will survive, but will I be able to sleep?
Thanks for the feedback.
