Made for the growing hiker, the adaptable kids' REI Co-op Tarn 40 pack can change shape thanks to compression straps, a removable top lid and an adjustable back panel for a variety of torso lengths.

  • Padded shoulder straps and hipbelt provide a comfortable carry; hipbelt pockets keep snacks or a phone at hand
  • Large stuff pocket in the front provides quick-access storage for an extra layer
  • Removable top-lid pocket allows options for organization
  • Loops on the front allow bungees or clips to be attached
  • Made to reflect our love for people and the planet through the use of recycled and bluesign®-approved materials
  • Recycled materials keep waste out of landfills; bluesign®-approved materials conserve resources and protect the health of the environment, workers and wearer (your kiddo)
