^At first when I trying the medium BTH and the large BTH, I was thinking the large was way too large on me being only 5 feet tall (I thought it would overwhelm me). The large version is quite substantial. In the end, I couldn't get past that the medium version can't be used all the time since it won't carry enough - besides it being only a couple hundred dollars cheaper. I opted for the large and I'm so glad I did. Sometimes I think the bag size needs some getting used to it especially if it's not usually a size you normally carry.
