>>939313A sawyer squeeze bag and sawyer mini are amazing fwiw.
Alice packs are cheap, but kinda suck. When loaded they carry the weight way too far away from your body. They aren't that comfortable. I've used my buddy's a few times and it's not half as good as my cheap Kelty redwing 50.
Which, coincidentally is a great pack you should look into. The new model isn't cheap yer, the last model is nearly as good and can find much cheaper.
