These are my go-to bags.
Top Left: Mystery ranch disc golf bag - For shorter missions and single technique sessions.
Top Right: Chrome Barrage - Water proof, bag expands for more storage space and the front webbed section fits extra clothes or another bag. Super well made.
Bottom left: No name military style bag - I like the compartments. It makes organization easy. Molle webbing so you can attach extra pouches. Not waterproof (only 500D denier) or that durable. I usually throw my swimbait pelican case in here and its pretty low profile.
Bottom Right: 5.11 Tactical 24 Hour Rush Bag: - Heavy duty and somewhat water resistant. Small profile (they make bigger packs) and I like the hydration pouch built in. Easy to organize because of the molle webbing and multiple compartments inside. This thing is built like a tank.
