FS-1 Mojave Wildland Fire Pack - Durable Firefighter Backpack for Wildfire Suppression | Lightweight & Ergonomic Design | Ideal for Firefighters, First Responders & Outdoor Emergencies

These packs are great! Very modular! I use for Wildland Fire, EMS, SAR and hiking. I've bought two so far. If you're a big guy, there is an extension strap you can buy. Checkout their website for more gear, clothing and accessories. Sometimes cheaper there also!
