Tui 42 Pack

Tui 42 Pack

The Kiwi Ultralight Tui 42 frameless backpack is designed for the most skilled ultralight hikers, perfect for both short weekend trips and thru-hikes alike!


Only a handful of each pattern are available, each is a unique design either hand-selected or created by our team. We will customize the torso length to fit you perfectly, but the hip belt attachment points also allow for torso length variability within a 7cm range. Please read our detailed guide on getting your torso measurement HERE.


We want to share the pack we at Kiwi Ultralight use ourselves in 4-season NZ conditions and we hope you love it as much as we have over the years!


These packs are custom-made and will ship within 1 week of order confirmation.

  • Features

    42L total pack volume:

    • 32L+ internal volume to the top of the shoulder straps (this is based on a 45cm torso length and will increase with increasing torso length). Additional volume is available above the shoulder straps depending on how full you pack the bag.
    • The external side and front pockets provide an extra 10L which includes the two 550mL hip belt pockets.


    HyperD 300, a 300-denier polyester diamond grid fabric. Durable and highly water resistant (although we don't seal the seams, so it will not be fully waterproof, and a pack liner is recommended).


    The packs weigh approximately 420g when complete. The hip belt can be removed to subtract 100g, and once you cut all the strapping to your desired length, the result is a ~300g pack!


    Hanging loop on the front of the pack.


    Roll down top helps compress your gear to improve structure.


    Adjustable hip belt provides a variable torso length within a 7cm range.


    Adjustable sternum strap.


    Stretch pockets on shoulder straps designed for phones, snacks, sunglasses, PLB, or other small items.


    All features can be seen in the video included in the image gallery at the top of the product page.
