JustPack Shackle, Large Backpack with USB Port

The Shackle is the biggest of the JustPack backpacks and the most kitted out. A USB charging port sits on the right side panel so a power bank can live inside, four compression straps pull the load in from both sides, and an aluminium carabiner hangs off the front for the things that never fit inside anyway.

Both shoulder straps carry silver reflective strips, which is worth having on a dark walk home. At 35 x 20 x 59 cm and 1.3 kg it is a genuinely large bag, and it comes in four colourways with the red JP plaque sitting low and centred on the front.
