Great day pack - Osprey Stratos 36 Pack

I've used this pack at least 3 times a week for the past year. This pack supports me while I perform trail building and maintenance. I haul a great deal of gear - tools (single jack, pick mattock, mini pick, silky, flags and flagging tape), medical kit supporting a crew of 10, wet weather gear, two liters of water, food, camera, communications. The available harness staps and other strap and back panel adjustments are fully functional; assist in fine tuning the fit. The bent stays and mesh back panel help provide a degree of cooling, but your back will still get wet. Of course, I am working and walking in the mountains. My only complaint is belt attachments pulling the pack straps forward are frayed and will soon break. I think it won't impact the overall functionality, but won't know until they go. While some ultralight packers may be able to use for an overnight, I cannot fit all the gear I would bring - 1 person tent, sleeping bag, water filter, extra food. Could use additional loops to carry tools - only offers one. I added a custom cord system to support additional gear.
