These synthetic tights from REI Co-op provide midweight warmth for cold-weather adventures. The recycled polyester and spandex fabric is peached for a supersoft next-to-skin feel, with a smooth face that lets layers slide on easily.

Semifitted to hug the body for optimum performance, they feature flat seams to reduce chafing, a crotch gusset for full range of movement, and a low-profile elastic waistband that stays comfortable under other layers.

Match the temp to the trek

  • Lightweight layers: best for moderate to cool temperatures
  • Midweight layers: best for cold temperatures
  • Heavyweight layers: best for below-freezing temperatures

Find your fit

  • Must be close to skin to efficiently wick sweat; should fit comfortably snug
  • Base layer is for moisture control; your mid layer is for warmth
