Apollo Bio-Seal Neck
The perfect answer to a loose or uncomfortable drysuit seal.
These rubber seals create a soft gasket around your neck. The extra bulk helps seal neck seals that aren't quite right.
The soft material can also help against chaffing caused by salt water crystals on latex seals.
To wear, carefully stretch the seal over your head and onto your neck. Unroll it and then get into your suit. Carefully stretch your suit seal and place it onto the Bio-Seal.
