The Roo
Atom Packs
The Atom Packs The Roo comes out of the UK cottage backpacking scene, designed specifically for hikers who appreciate modern technical fabrics and artisanal craftsmanship. It fills the gap between mass-market nylon bum bags and hyper-minimalist ultralight sacks, offering a dialed blend of durability, weight, and trail utility. Available in multiple technical packcloth options such as VX21 (X-Pac) or EcoPak, The Roo offers superior tear strength and excellent water resistance for wet weather. The pack features a sculpted, ergonomic rear panel that sits close to the torso, minimizing movement when you pick up your pace. A heavy-duty, weather-resistant zipper spans the main cavity, while an external front stretch mesh pocket provides immediate, one-handed access to snack wrappers, lip balm, or a pack towel. At roughly 3.5 ounces, it packs down small enough to act as an auxiliary pocket for a thru-hiker’s main kit, yet offers sufficient structure (available in 1.5 L and 2.5 L volumes) for standalone trail outings. The main drawback stems from cottage production: purchasing directly often means dealing with stock limitations, pre-orders, and shipping wait times. **Highlights** - Advanced technical fabric options (X-Pac / EcoPak) for high durability - Front stretch mesh pocket for quick trash or snack stowing - Ergonomic patterning hugs the waist to prevent trail bounce - Available in 1.5 L and 2.5 L capacity configurations - Clean internal organization with water-resistant zipper closure **Watch-outs** - Cottage gear availability can involve production batches and shipping delays - Fabric seams are water-resistant but not fully seam-welded

Bataan Del Día
Cotopaxi
The Cotopaxi Bataan Del Día is an approachable, high-volume fanny pack geared toward casual day hikers, car campers, and travel enthusiasts. Its signature appeal lies in its one-of-a-kind color blocking, constructed from leftover fabric scraps from larger manufacturing runs to reduce industrial waste. At 3 liters of storage and roughly 3 ounces in weight, the Bataan provides one of the best space-to-weight ratios on the market. It easily swallows a phone, a compact windbreaker, a beanie, sunglasses, and several snack bars. Inside, two interior mesh organization sleeves keep small valuables from pooling in the bottom of the main cavity, while a wide, durable webbing belt distributes the weight comfortably across the waist or torso. Because the Bataan uses lightweight repurposed ripstop nylon without rigid backing or foam padding, it is completely unstructured. If packed unevenly with hard, angular items like keys or multitools, those objects can poke through the back panel. Additionally, the nylon offers minimal water resistance, so items inside will require a waterproof zip-top bag during serious rainstorms. **Highlights** - High volume-to-weight ratio (3 L capacity at approximately 3 oz) - Eco-conscious construction using 100% repurposed remnant fabrics - Every pack features a unique, one-of-a-kind color scheme - Two interior mesh dividers for sorting smaller essentials - Budget-friendly price point accessible to casual trail users **Watch-outs** - Totally unstructured design allows sharp objects to poke through the back - Online ordering does not allow you to pick your colorway
