Smartwool Clothing

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.

How to Choose Hiking Socks

Select your sock height

• No-show: Little protection against skin-to-boot abrasion. Best with low-cut footwear like trail-running or light hiking shoes
• Ankle: Covers your ankle bone and offers some protection. Best for low- to mid-cut shoes and boots
• Crew: Extends a few inches above ankle bone and protects against boot abrasion. Good for boots or shoes
• Knee-high: Typically used for mountaineering, provide warmth and protection against high-cut boots

Choose your preferred cushioning level

• None: Ultralight, breathable socks designed for use in hot weather or as sock liners
• Light: Moisture-wicking and comfortable at the heel and ball of your foot; relatively thin and better for warm conditions
• Medium: Targeted cushion in the heel and ball of the foot for hiking and backpacking; warm enough for moderate to cold conditions
• Heavy: Thickest and most cushioned; best for long trips, tough terrain and cold

Select a fabric

• Choose a moisture-wicking and quick-drying material like wool, polyester or nylon.
• Spandex is often added for its elastic properties to prevent bunching or wrinkling.
• Cotton isn't recommended as it absorbs moisture, takes longer to dry and cools down quickly.

Find your fit

• Choose based on your foot size, not shoe size.
• If you're between sizes, size down to avoid excess material that can bunch up and cause blisters.
• Socks should feel snug but not tight, and the sock's heel cup should naturally line up with your heel.
