Thread: 40 bag ok?

  1. #1

    Default 40 bag ok?

    I know, I know, this is a newb question, I'm a little indecisive on this and just need a push. Haha. I've been checking ATweather.org and temps in SoCal have been around the low 40s at night. I have zpacks 20 & 40 Bags. I am trying to decide between taking the 40 with base layers or the 20 and no base layers. I will have a light weight down jacket I'll be carrying either way.

    Any advice is appreciated. I'm starting on the 21st heading north.

    I would go with a 20deg quilt or bag. You will be surprised how cold it gets at night pretty much along the whole trail. I had a 20 quilt and bivy and often still wore my clothing layers to stay warm. You will also get colder easier as you lose weight on the trail.

    After a while on the trail the down 40 is more like a down 50

    and the average nighttime low at 11000 ft in Sierra is less than 40, closer to 35, almost always hitting mid-upper 20s during one week each summer

    Deserts and mountains both get colder than you think. 20* bag for sure. You can always vent for only a couple more oz

    I used a ZPacks 20 Degree on my JMT Thru Hike. I'm planning on mid weight sleeping clothes versus thermasilk for my PCT Thru. I had many nights I slept in all,of my clothes. Dates June 29-July 15 2016.

    Hope this helps.
