The Big Papa Bag fits quickly into the Big Papa Harness (sold separately or with a bag as the Big Papa set), allowing you to carry large, bulky items on your bike.

  • 17 litre expedition size to cover various trips
  • Durable materials and a reinforced construction
  • Highly water-resistant with waterproof fabric and a roll-top

The Big Papa bag slots neatly into the Big Papa Harness, allowing you to pack up and get out riding quicker, whether it’s the daily commute or month-long tour. (Please Note: the Big Papa bags require the Harness to attach to your bike. The two sections are also available together as the full Big Papa set.)

Made from lightweight and tear/abrasion-resistant VX21 fabric, the Big Papa Bag is designed to last, ride after ride, through even the most jaw-clattering of terrains. Handmade and designed on the edge of the Peak District by our talented factory team, the Big Papa Bag comes with a 25-year Alpine Bond.

VX21 is also fully waterproof. Combined with the roll-top closure (3 turns should do it), this makes the seat pack highly water-resistant, protecting your kit in bad weather. The stitching isn’t seam taped though so we’d always recommend wrapping any electronics or down items in a dry bag – especially if you expect to be fording any rivers!
