Works for old folks too!
I'm 63 years old and travel a lot on business. I had 3 back operations so have been using a roller bag, problem is that you have to carry and lift it a lot. Used a cheap little back pack I got at a meeting and liked it so started looking. Tried several and the Surge was the best. Just got back from a business trip to Portugal and it met all my needs. Very good alternative to a roller briefcase.
