Holdalls are the preferred choice for companies and charities who undertake fundraising expeditions, group treks and school trips. Most of these trips have vehicle and/or porter support and a holdall is much easier to stack in a vehicle or attach to a horse for transportation. Buy a reasonable quality model as it will get pulled around by its straps. For versatile carrying options, ensure it has a detachable shoulder strap and check if the handles are long enough to be able to wear it as a ‘backpack’.
