Both the HandiHoldall 400 and HandiHoldall 175 litre models have been designed to be completely waterproof. The HandiHoldall 330 litre is specified using a different type of fabric which is water resistant and will therefore only provide limited protection against heavy downpours.
To make the HandiHoldall 330 litre as weather and water resistant as possible, all of the seams are sealed on the inside by the same type of tape that’s used on tents and other outdoor products. However, in very wet conditions there remains a risk of some water ingress and that’s why we advise customers to pack and protect any delicate items in bags before packing them into the HandiHoldall.
