Backpack and Water Bottle Combo
Everything you need to get to the track properly kitted out, the KARTR Water Bottle & Backpack Bundle pairs two of our most practical pieces into one combo. Whether you're heading to a race weekend, the gym or just carrying your kit day to day, this bundle covers hydration and storage in one go.
The KARTR x Under Armour backpack is built from a 93% polyester, 7% nylon blend using UA Storm fabric, making it highly water-resistant and stain-resistant. With 27.4 litres of capacity, a soft-lined laptop pocket that fits up to a 16" laptop, a side pocket built for a 32oz bottle and secure zip front pockets, it's designed to carry your gear without feeling bulky. The LEVELED strap system keeps weight distributed evenly across your shoulders, so it stays comfortable even on longer days at the track.
The KARTR water bottle slots straight into the backpack's side pocket, made for exactly this pairing. It's double-walled stainless steel with vacuum insulation, holding 950ml and keeping drinks cold through a full day in the sun. A wide-mouth foldable straw, rotating handle and anti-slip patch round it out, giving you a bottle that's as practical as it is durable.
Together, the bottle and backpack give you a complete, hardwearing setup for race day, built to handle whatever the paddock throws at it.
