Used this Deuter bag (pictured: Air Contact 55 + 10. An older model, unsure if it’s still in stores but I’ve linked a comparable one available at Walmart!) for a multi-day, ~20 mile hike in New Zealand and it was a DREAM. Nothing worse than a pack with flimsy buckles or inconvenient compartments, I highly recommend Deuter bags based off my experience! Sleep mat pictured is just an old one as well, but it definitely did the job! Found a comparable one for you also at Walmart 🫶🏻
