A little late to the party here, but searching for threads on Everki backpacks and drew me here, with the excellent review of the Concept Premium.
I, for one, just ordered a new Everki Versa Premium backpack (20% off, free shipping, and 4% cashback, so about $161 all-in). Hasn't arrived yet, but will post a review of it somewhere. I'm coming from a
Codi Sport-Pak which was company-issued.
That was a good bag, very durable for the 5 years and hundreds of flights I've used it, but definitely showing it's age. Aside from the gadget pouch zipper seam coming apar and the occasional zipper teeth jumping on the laptop compartment, it's held up. There is some fraying here and there, but it's all wear-tear cosmetic stuff. It's also a bit on the big side and I'm looking for a more refined look.
Everki Versa Premium is a bit more compact, but still plenty of room, great organizational features, and looks great (imo). I was deciding between it and the Tenba Roadie Executive backpack, but chose the Everki in the end based on style, (perceived) functionality, and price (Tenba is available for $165, but couldn't find any sales to sweeten the deal - Everki with discount is comparable). Can't wait to get it and try it out!
