As a father of six I have some insight to the traveling habits of high school/college aged people.  When we all meet for a family gathering I've learned that when my girls (I have 3) were in high school they often carry more clothes and other personal items than the boys do.  As they entered college they relaxed and brought less "stuff."  As they grew into their late twenties the trend reversed itself again and both they and even the boys carried larger and heavier bags.  Another observation relative the this item is that they were at their most adventurous during their college years, before concerns of jobs and family take over.  Hiking in Pyrenees, living in downtown Tokyo, exploring volcanoes in Hawaii, etc.

The Thule 38 Liter Carry-On is a beautiful bag. As a lifelong traveler I admire it's design and appreciate it's quality.  However, for my needs it is too small and it has features that I will never use.  The backpack strap is well designed but unnecessary for me.  However, it is perfect for my 19 year old daughter.  I loaned this to her and she LOVED it.  She is in college 1000 miles from here home so she takes quite a few flights each year.  The Thule performs like a champ, rolling up and down the terminals just like all of the other, regular carry-ons.  It's when she gets to where she is going that the straps come out and it converts into an easy to carry backpack.

Thule is known for both their quality and their attention to detail.  This product is no exception; from the built-in sunglass case to the multiple handles everything is well thought out and excellently constructed.  Good luggage costs a lot when you buy it, cheap luggage costs more down the road. This Thule bag is great investment and would make a fine High School graduation gift.
