Hydrate. Carry. Explore. Everything in One Pack.
The EVERFUN 18L Hydration Backpack is built for hikers, cyclists, trail runners, and outdoor adventurers who need reliable hydration and smart organization in a single lightweight pack. With a 2-litre food-grade PEVA water bladder, 9 functional pockets, a built-in rain cover, reflective strips, and a 3D breathable padded back system — this is the day pack that keeps up with every adventure, in every condition.
2L Food-Grade PEVA Water Bladder – Upgraded Hydration
Includes an upgraded 70 oz / 2-litre water bladder made from food-grade PEVA material — BPA-free, taste-neutral, and safe for long-term use. The high-flow bite valve delivers water on demand without stopping, and the mouthpiece cover protects the valve from dirt and damage between sips. The bladder is replaceable and upgradeable to 3L / 100 oz for longer expeditions. A dedicated insulated compartment keeps liquids cool for up to 6 hours with ice packs.
18L Main Compartment – 9 Functional Pockets
The 18-litre main compartment (18.5" × 10.5" × 6") is large enough for clothing, a first-aid kit, notebooks, pet supplies, and more. Nine thoughtfully designed pockets keep everything organized and accessible: a built-in mesh pocket for personal valuables, an exterior upper velvet-lined pocket for glasses, cameras, and phones, and side mesh pockets for trekking poles or water bottles. A designated space between the outer and middle pockets fits a helmet securely.
Built-In Rain Cover – All-Weather Ready
The pack features a built-in integrated rain cover — no separate cover to lose or forget. Pull it out when the weather turns and keep your gear dry on rainy hikes, bike rides, and trail runs. High-density nylon fabric adds an additional layer of water resistance for everyday wet-weather use.
Reflective Strips – Low-Light Visibility
Reflective strips are integrated into the pack design to keep you visible to drivers and other trail users in low-light conditions — essential for early morning runs, evening rides, and dawn hikes where visibility matters most.
3D Breathable Back System – Lightweight & Comfortable
At just 2 lbs, this pack is exceptionally lightweight without sacrificing structure or support. The ultra-elastic 3D breathable padded back panel promotes airflow to reduce sweat build-up during high-output activities. Adjustable chest and waist straps distribute the load evenly across all body sizes — keeping the pack stable and comfortable on the longest days out.
Versatile – Hiking, Biking, Trail Running & More
Designed for hiking, mountain biking, trail running, cycling, camping, and outdoor day trips — any activity where staying hydrated and organized on the move is essential. Lightweight enough to forget you’re wearing it, capable enough to handle everything you bring.
Material
Outer shell constructed from high-density nylon fabric — durable, abrasion-resistant, and water-resistant for everyday outdoor use. The water bladder is made from food-grade PEVA — BPA-free, flexible, and taste-neutral. The back panel and shoulder straps are padded with ultra-elastic 3D breathable foam for comfort and airflow. The rain cover is integrated into the pack and made from lightweight waterproof nylon. All zippers are smooth-pull and reinforced for trail durability.
Stay hydrated. Stay organized. Stay moving — whatever the trail throws at you.
