You are looking at a zetaliner for HGU-55/P type flight helmet. This liner absorbs the shocks inside the flight helmet and protects therefor the pilot and also makes flight time more comfortable. These liners are made by : Oregon Aero. Different sizes are available. You need to know your size if you want to order one as I have only the part number and size marked on the liner. ( it does not mentionne Medium - Large or XL, just a number ) liner is used but in excellent condition. These are hard to come by. I have stumbled on a small box containing several of those. This auction is for 01 Zetaliner !!!! Complete your helmet right now with this one. No more more after these are gone. Picture was taken as a reference , liner on sale is similar in condition as the one seen in the picture. SIZES : 95132A - 95133A - 95134A - 95142A - 95143A - 95144A - 95152A PLEASE ASK BEFORE BIDDING IF YOU DESIRED SIZE IS AVAILABLE !!!! See also my other aviation items on sale right now.
