Front Utility Pack Accessory
Zpacks
The Zpacks Front Utility Pack Accessory is an ultralight piece of kit built directly for long-distance thru-hikers who want quick-access gear security without sacrificing weight. Weighing under 3 ounces, it functions seamlessly as an independent fanny pack or integrates onto the front harness of a larger backpack. Constructed from ultra-durable composite fabric (Ultra or DCF) with fully taped seams and a water-resistant zipper, the Front Utility Pack excels in sustained wet weather. Hikers can keep phones, cameras, paper permits, and headlamps completely shielded from continuous downpours without adding supplemental dry bags. Its 1.7-liter capacity is precisely measured to carry dense everyday carry items without protruding too far forward. Mounting versatility is a major asset: it comes with hardware that clips directly into the sternum straps or load lifters of a main pack, balancing your overall pack weight by placing dense items on your chest. The primary limitation is the strap design. The minimalist 3/4-inch webbing belt keeps weight down but will dig into the waist if the pack is overloaded with heavy gear. **Highlights** - Fully taped seams and waterproof composite fabric construction - Extremely light 2.9 oz trail weight - Modular hardware clips directly to backpack sternum straps or hipbelts - Interior mesh pocket keeps cards and trail IDs separated - Excellent durability against abrasive brush and rock friction **Watch-outs** - Narrow webbing waist belt provides zero padding for heavy loads - High price relative to its compact 1.7-liter volume

Bumster
Gossamer Gear
The Gossamer Gear Bumster is a purpose-built hiking waist pack that hits an optimal intersection of low weight, practical dimensions, and sensible pricing. Long popular with thru-hikers on the Appalachian and Pacific Crest Trails, it functions equally well on casual afternoon trail runs and day hikes. The Bumster measures roughly 10.5 inches wide by 5.5 inches tall, giving it a flat, rectangular shape that sits comfortably against the lower abdomen or lumbar. Made from tough recycled Robic nylon, it shrugs off scuffs against granite and brush without tearing. A key design detail is the wide 1.5-inch webbing belt, which prevents the strap from cutting into your hips or rolling up when worn underneath a loaded backpack hipbelt. Internal organization includes a main cavity with an interior pocket and key clip, plus a rear zippered pocket against the body that provides secure, sweat-resistant storage for passports, cash, and phones. The pack lacks external water bottle sleeves and rigid padding, meaning you need to pack it mindfully, but for under $30, its value is difficult to match. **Highlights** - Wide 1.5-inch webbing waistbelt avoids twisting and pressure points - Rugged, recycled Robic nylon delivers high tear resistance - Rear zippered security pocket rests flat against the body - Flat, wide geometry minimizes bounce during brisk hiking - Very accessible price point for a technical outdoor pack **Watch-outs** - Water-resistant fabric will eventually wet out in sustained downpours - Lacks external attachment loops or elastic gear cords
