I have an original Neoa Air, 15 ounces full length. My son is now backpacking with me and need a pad so we went to REI to get the new Xlite Neo Air pad. My current pad makes a little noise when you move around but its not that big of a deal. When we tried the new XLite Neo Air, holy cow it was loud! I'm talking real loud. I was excited to see its down to twelve ounce for the full length and I am a semi gram weenie, but no way I was going to get the new Xlite. Cool thing is my son loved the zlite and it now has the sol type of reflective material like the ridge rest now. That saved me $110.00. So yes my 7 yr old is awesome, but be for warned about the new Neo Air Xlite. Ear plugs required if you or any one close to you has one, yes it's that loud.
