So Far So Good
Used it first time for a 4 day trip on the AT from Springer Mtn to Neels Gap. First day rained continuously. None of the compartments leaked. The main compartment definitely seems very waterproof, ie submergible. The other zippered compartments kept the water out completely for me during this one day of steady rain, but I would tend to believe they would eventually leak given enough time or submersion. The belt and harness are very comfortable. Hydration system worked great with a camelback. Held 30-40 lbs no problem, and if I needed a larger pack, I would definitely consider the Naos 70 based on my experience thus far with this pack. Watching everybody else on the trail struggle with their non waterproof packs, rain covers, etc. in the rain made me a believer. Highly recommended.
