Recommended clothing systems: Backpacking in the Mountain West

What clothing is necessary for backpacking in the Mountain West in 3-season conditions? Let’s discuss.

I define the Mountain West as the semi-arid ranges of the Sierra Nevada, Intermountain West, and Rockies. Examples:

  • Pacific Crest Trail in California and southern Oregon
  • High Sierra, including the John Muir Trail and multiple high routes, e.g. Sierra High Route, Kings Canyon High Basin Route
  • Colorado Trail and Pfiffner Traverse
  • Northern Rockies: Wind River Range, Yellowstone, Bob Marshall Wilderness, and Glacier National Park
  • High Uintas and Wasatch
  • Sky Islands in Arizona and New Mexico

From theĀ Core 13 Clothing Collection, I recommend just ten items for the Mountain West. Mix-and-match them to create appropriate clothing systems for each season. Watch the video above for a general explanation, and review the lists below for specific recommendations.

    Am I reading the chart wrong, or are you suggesting wearing depends as underwear if you wear pants full time?

    • Andrew Skurka August 23, 2017 at 4:15 pm #

      You might be kidding, or you might be serious, since I’ve heard other people say that I had that initial impression.

      “Depends” is in the “Priority” column, which I use to indicate its importance (or lack thereof). Usually in the Mountain West, I wear running shorts whenever I can, and bring trekking pants for protection against sun, brush, bugs, and chilly conditions. I only recommend underwear if you plan to wear your pants full-time. In that case, leave the shorts at home.

        I am just kidding. I’m a full time pants and underwear guy, no depends. In the Whitney zone however……..šŸ˜

          That is EXACTLY what I was thinking also . . .

    Andrew, I have enjoyed reading and watching your “Core 13.” Unfortunately, I don’t get out backpacking but a couple of times a year–one of these years that’s going to change. I think I have what I need fairly dialed in but…I always learn something from you. Thanks!

    Hey Andrew,

    I have enjoyed your blog and talks posted online immensely. Also – I now own the Pack Polo shirt from your kit and it is amazing.

    I’m curious in which ways you’d alter your clothing system for the Cascades in WA from this system. Thanks!

    • Andrew Skurka August 24, 2017 at 2:54 pm #

      If your route is mostly or entirely below treeline, you can wear a short-sleeve. In spring and fall, I might grab a merino shirt rather than than poly, because it’ll be less chilling when wet.

      On most trips, rain pants and sleeping clothes will be packed, not left at home.

    Andrew,
    I just completed a trip into the sawtooth mountains to view the eclipse and I used your ‘clothing system’ to pick out my gear. I brought a down vest because I don’t own a light puffy jacket. Great trip all around.
    Do you wear the long pants under rain pants or just go with bare legs?

    • Andrew Skurka August 25, 2017 at 11:18 am #

      Glad it worked well.

      I will wear long pants under my rain pants if temperatures warrant it, but otherwise I’ll only have shorts on underneath.

    Thoughts on Merino for the mid/fleece layer? Ive been using a Montbell Trail shirt (button up flannel) but have been think about a hoodie like the Black Diamond Coefficient or Pat R1 or Ice Breaker Descender…

    Also what are your thoughts on wind shirts? Your bud at Bedrock and Paradox seems super into them: https://bedrockandparadox.com/2017/04/03/rab-windveil-windshirt-evolution/

    • Andrew Skurka August 27, 2017 at 3:45 am #

      I prefer poly for fleece — lighter and retains less water, less expensive, and the smell is much less of an issue for this garment.

      Wind shirts are niche. Still will need a rain jacket and a fleece if you expect cool precip. At that point, might as well leave the wind shirt at home.

    Hey Andrew! Awesome list. Thanks for putting this together.

    I noticed you’ve got the Patagonia Down Hoody listed as your insulated jacket, instead of what seemed like your long-time go-to SD Down Hoody. Any reason for the switch?

    • Andrew Skurka September 11, 2017 at 4:08 am #

      I still use the SD Down Hoody and would recommend it. There are more premium jackets available (e.g. lighter per warmth, due to lighter materials and loftier insulation) but usually you’ll have to pay more, too. In this particular case, the reason I highlight the Patagonia jacket is so that there’s some diversity among brands listed. I don’t want to give the impression that peddling SD products is the underlying motivation for Core Clothing.

    Just wanted to give thanks for this timely post. I recently returned from a 3 week trip in the Sierras. This post came out about 10 days before I left. What was not on my list was a fleece. I agonized about carrying another 8-10 oz of clothes, but in the end decided on bringing it. And I am so glad I did. Most of my past Sierra experience has been in early August, and between a long sleeve shirt and my puffy jacked I have never really needed the fleece. But the cooler temps of late summer and early fall, just one + month, really made a difference. A week ago yesterday a cold front moved through the Sierras and brought some rain, hail and snow, depending where you were. When that front moved on, the cold stayed. I hiked in my fleece most of the day the last 5 days of the trip. Even before that, it was great to have another layer to wear instead of always putting on my puffy.

    Your recommendation was spot on, and I thank you greatly for it!

    As an aside, I also brought a 2oz reflective mylar emergency blanket I have had for 30+ years to use as a ground cloth for cowboy camping. The reflective mylar really works! I definitely could feel the reflected heat from beneath me. My sleeping pad is an older neoair with an R value of 5. Between that and the reflective mylar temperatures into the low 20s and high teens were no problem in my 30 degree quilt with my rain gear on top of my other clothes. Never needed to wear my puffy while sleeping, just my long sleeve shirt, fleece, and rain gear if it got really cold or was windy.

      Glad to hear that the advice was spot-on. Agree, that the fleece is crux when temps get brisk later in the year. Don’t poo-poo it for August, however, especially if you’re in an active monsoon cycle.
