I have one of those ubiquitous hard foam cases, concert size. It came with two straps and loops to attach them. Actually very comfortable to wear backpack style.
We've gotten basic gig bags from Mike (hoosierhiver) at Mainland Ukuleles and heavy-duty gig bags from MusicGuyMic (MGM). They all have backpacks straps and both Mikes are great to buy from.
Asfab Music in Pasadena California is apparently the only U.S. distributor of Fusion gig bags. Here's the website. http://www.asfabmusic.com/home.html
It requests that anyone interested in buying a Fusion gig bag send an email to nick@asfabmusic.com. I'm about to email Asfab Music and I'll post in this thread any information I get.
