REI Co-op Zephyr

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.

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.
