The SG-FIELDCORE Frontier Sling Pack takes everything anglers love about the Frontier Chest Pack and reimagines it in a shoulder-sling format built for versatility, comfort, and all-day wear. Designed for anglers who move fast and fish hard, the Frontier Sling Pack delivers the same intuitive layout and modular storage as the chest pack - but with a purpose-built, ambidextrous sling strap that does more than just hold the pack in place. This isn’t your average shoulder strap. It’s fully reversible, ventilated, and loaded with attachment points for SG-FIELDCORE accessories, keeping essential tools at your fingertips. The real difference? Our patented Ventcore® technology, built right into the sling. Engineered for breathability and support, it keeps you cool and comfortable whether you’re hiking deep into the backcountry or swinging streamers on a hot summer day.
