"If you have not heard of Spire they make some great laptop backpacks, bags, and sleeves. Last year we took a look at their Zoom laptop bag and it received a 10 out of 10 score and our Recommended Award. This time they sent us one of their courier bags the Endo, which will fit most laptops up to 15.4-inches. The Endo is one of three of Spire's new courier bags. The other 2 in the series are the Viro, which fits laptops smaller than 15.4-inches and the Mojo, which fits laptops larger than 15.4-inches. All three of these bags are practically the same, just different sizes, so if you don't have a laptop that will fit the Endo it will either fit the Viro or Mojo."
