Hiking packs should be versatile and able to accommodate all our gear without being too bulky. The Thule Nanum 18L Backpack is one of our go-to packs for day hikes due to its streamlined design, lightweight construction, and adequate capacity. Made from a durable 420D nylon, the Nanum is super durable while still being lightweight and has a DWR coating for water resistance. The main compartment opens wide for easy access and has a hydration compartment that can store a water bladder for easy hydration. A smaller zippered compartment has internal organization pockets to store all our smaller items and a key ring to keep our car keys secure. Mesh side pockets allow us to carry water bottles, and bottom compression straps allow us to strap a jacket or other bulky items to the bottom of the bag. A bungee cord lock lets us secure our hiking poles to the back of the bag when they are not in use, and a removable hip belt lets us customize our carry options. Lastly, the tensioned mesh back panel keeps the pack off our back for breathability so we don't get sweaty when hiking in warmer weather.
