I asked a few of my girl freinds.. they all said bigger is better..
It is all in the hips ya know..
And all were quite content with it being 3 in one..
Light is good...Waterproof is a must..And nothing that glows in the dark....
Best part 1 size fits all..
All joking aside I vouche for the Cabelas Alaskan..
Its a comfortable fit, holds alot of weight,sturdy framework.and most importantly keeps everything dry..
