Hyperlite Mountain Gear Southwest 70L Ultralight Backpack

I really like this pack. It's lightweight and comfortable but has enough volume for a long-ish hike. My only reservation is that I was under the impression it was supposed to be 'hihgly water restant' but the first time I used it on a rainy day, some of my gear got wet ... It's possible that this was user error of some sort. I will have to test it again the next time I am out in the rain.
