“Only weatherproof if it full and water can’t pool on top. We just took a trip where we got a lot of rain over two days. Was dry inside when travelling as it was full and water would run off. When things got pulled out and it was fairly empty (so water pooled on it) and was left on top of the cars for a 2 days- it leaked… a lot. All zippers were fully covered. So won’t be leaving gear in it once we reach our destination anymore.”
