Mountain Hardwear Field Day 22L Backpack It's a Good Day to Have a Good Day The Field Day 22L is for people who need a pack that's smart enough for work but tough enough for the trail. At 22 liters, it sits in the sweet spot-large enough for a full day of hiking or a solid workday commute, compact enough to not feel like dead weight. The stretch woven front pocket fits layers and accessories, while dual water bottle pockets keep you hydrated without eating into main compartment space. Like all Field Day packs, it features a foam backpanel with breathable mesh-overlay shoulder straps-the kind of engineering that keeps you comfortable mile after mile without forcing you to choose between support and airflow. Webbing tool loops and cord tool keepers let you lash external gear, while the hydration-ready design includes a reservoir hang loop and hose port for hands-free drinking on the move. The removable sternum strap adds security, and reflective details on the bike light clip and shoulder strap make evening commutes safer. It's durable and functional for use in the city and on the trails.
