It didn't work in my case. Originally, I thought these garments would be really useful, but then I looked more closely. I really think the company is advertising their products somewhat under false premises, and the owner even admits so himself (i.e., fully loaded, the only way to even attempt to beat the baggage fees, the jackets and vests are not very comfortable to wear). The way the owner/founder interacts on forums then finally turned me off. I am sure he'll be reading this, and I can only hope for the sake of his company that I am in the minority and that he gained more customers through his actions than he lost. All the best! MM
