Mercenary bag question

Hi, I've recently been interested in the Razer Blade 15 and I need a bag to carry it around for travel, etc. The Mercenary Backpack's cool and slick design has caught my eye but the spec sheet mentions "Made to fit the Razer Blade 14 May fit other laptops of similar dimensions" so I was wondering if the size of the Razer Blade 15 was sufficient and close enough to the size of the Razer Blade 14's compartment? I'd appreciate it if someone could help me out with this question, thanks!
