Known for his monster-mile backpacking expeditions, including the Sea-To-Sea Trail, Great Western Loop, and a circumnavigation of Alaska, Andrew Skurka is a world-renowned outdoorsman.
To hike or backpack anywhere in three-season conditions, I propose that a total of just 13 items of clothing are needed. I call them the Core 13.
To be sure, there are thousands of options, and clothing is the subject of much marketing hyperbole in the outdoors world. Identifying the 13 was not an easy task.
But after years spent hiking and exploring I have come to the below baker’s dozen list. For more in-depth info on each part, follow the linked text to full articles on my site, and see page 2 of this post for sample clothing systems. Happy hiking!
1 & 2. Base Shirts: Start with a short- and long-sleeve shirt made of knit polyester, merino wool, or cotton (hot and arid environments only), featuring a chest vent and neck collar. Use the short-sleeve for warmer conditions, and the long-sleeve when it’s cooler and/or when protection from brush or sun is needed.
