A buddy of mine had one and we went on a ski trip and it didn't take long to realize that my standard roller bag was super lame compared to this thing. Not only does Dakine have the sickest designs on the outside, the compartments are super sweet and help you stay organized on the inside. I wear a size 13 shoe and I can fit one pair comfortably and up to 1.5 pairs in the smaller pockets on the top half(inside). I had a hard time deciding between the 90L and the 120L. I came to this conclusion. 90L can pack a little over 50lbs of clothing which gets you close to the standard limit on an airline. But with today's airline economy, you might just get the 120L since you have to pay to check it anyways and have enough space to practically fit your whole closet into it! Either way you go, these bags are so sweet and people in the airports look at them probably wishing they had one!
