Nitrous Express GM EFI Race Jet PackNX Jets are manufactured on CNC equipment, and are guaranteed to be within . 0005 of specified jet size. In recent testing, using the same jet size, NX jets out flowed the competition by 35%! That's right 35% more flow through the same orifice, how you ask? The NX jet was designed to be more than just a hole in a piece of brass; its contoured inlet and multi stepped outlet allow turbulence free flow with no restrictions. Warranty Certificate of Origin

I have a skinny 9yo and we always have issues with pants, jeans, shorts, pyjamas etc. being too big in waist. I was absolutely stunned that these actually fit him without the need to be taken in!!! But there is still plenty of stretch for bigger bellies. The shorts are a little longer than what we're used to for pyjamas - they go down almost to the knees, but the kid likes it. Although he's 9, I ordered size 8 and they fit great. Will get another set!
