Despite what the name suggests, the brand Dew makes drybags. Their AVO backpack is an 18-liter roll-top daypack that’s 100% waterproof & 100% airtight to keep your gear 100% bone dry. The bag features a water-resistant outer pocket, ventilated ergo shoulder straps, reflective trims for cycling & night visibility, and it’s got a removable padded laptop sleeve with shoulder straps for when you want to travel even lighter.
