I'm ready for my first S240 or similar adventure. I might be over 24 hours depending on how long I'll be at friends. These are the panniers I am using for Tour De Jasper, with less stuff in them as it is a supported trip. My friend's daughter is having a graduation BBQ at her parent's and there's camping! Also, it's not too far out, about 20 kms or so each way, so it's perfect for bicycling.
For camping gear I have:
1 MSR Hubba tent (1 person)
1 Therm-a-rest Woman's Ultralight sleeping pad
1 MEC Merlin Sleeping bag (under a kg!)
Black Diamond Headlamp
