Replacement neck gasket for Kokatat dry wear. 
 
Note: These gaskets are as sent to us from Kokatat. They have changed suppliers in the last year so the gaskets look slightly different than in the past. This is the same gasket Kokatat would put on your suit if you send it back to them for repair. The measurements are the same on these gaskets where you attach it to the dry wear and for the neck opening diameter.
 
These latex seals for drysuits/tops are as good as you can buy. Comes in 2 sizes, small and large. Small suits come with a small gasket, all others come standard with a large. Attach with the PB-300, or Aquaseal (sold separately). 
Standard seals are .026" thick.
