The BUTTERFLY story in short:

  1. Comfort: First of all it's comfortable. Really comfortable.

  2. Durability: Thanks to an efficient structure, we were able to use more heavy duty materials than what is commonly used in ultralight bags, and maintain a low pack weight.

  3. Efficiency: Everything is designed to fit your gear and work in many ways of use, from the compartments proportions up to the lashing points.

  4. LightweightYes, it's a lightweight pack, and in relation to its durability and carrying comfort it's an extremely lightweight pack.


  • Removable waist belt, back frame, back pad, and lumbar pad, allows you to reduce the weight of your backpack, depending on your use.
  • Ultra comfortable, curved and wide shoulder straps.
  • Load lifters for pulling the load close to your center of gravity.
  • Uniquely designed pack shape makes the load ride high and close to your center of gravity,  prevents the pack from pulling you backward and down, providing increased carrying comfort.
  • Anti-slip material on the lumbar pad allows the waist belt to sit firmly on your waist, significantly reducing the downward slip of the backpack when carrying high weight.
  • Two open side pockets for bottles or long objects.
  • Hydration bladder hanger and two hydration ports.
  • Multiple lashing points on the front and bottom of the pack allows you to attach additional gear with a lightweight cord.
  • Large front pocket made of durable mesh.
  • Made in Israel.
