Related Expert Advice articles
What material is best?
Wool is moisture-wicking and odor-resistant, while synthetic fabrics are more durable and less expensive.
Match the temp to the trek
Lightweight layers are best for moderate to cool temperatures. Midweight layers are best for cold temperatures. Heavyweight layers are best for below-freezing temperatures.
Find your fit
To be able to wick sweat efficiently, your next-to-skin layer needs to actually be next to your skin. A comfortably snug fit everywhere is your goal.
Types of packs
Backpacking packs can be 30 to 70-plus liters. To choose the right capacity, consider trip duration and the gear you’ll bring.
Backpack features
Think about the frame type, location of important pockets, padding and ventilation, among other things.
Backpack fit
Your pack should be correctly sized for your torso length (not overall height) and hip circumference. A fit-expert at an REI store can help.
