Drysuit Bellows Neck Seals G Dive Neck Seals Sizing

The standard design neck seal found on most drysuits offers a {10in | 252mm} mounting diameter at the base, three different latex thickness options, and a variety of choices for neck sizing - see sizing chart below. As a general rule, the seal opening should be trimmed to be no smaller than 80% (i.e. maximum of 20% less) than your actual measurement of the relaxed neck circumference, tighter than that could cut off blood flow to your brain.

Latex Thickness Options:
  • Flexible (FD): 0.5mm to 0.7mm - More flexible with more stretch than the standard
  • Standard (GD): 0.7mm to 1.0mm - Usual thickness found on most seals
  • Heavy Duty (HD): 1.0mm to 1.4mm - Thicker, thus more durable, but less comfortable

My recommendation is to choose the one size smaller than what fits you on the chart. I bought 2 to get the size right.

Size chart is wrong
1
Sep 26, 2019
Very disappointed with this item - I was at the upper end of the medium size on their size chart and it is too loose. I tried it on, and it felt like an OK fit, and that I probably would not have to trim it. AFTER installing it on my drysuit, a process which was very time-consuming and required the help of 2 friends, I found that the seal is indeed too large and it leaks all around. Very annoying to have measured myself, compared to the size chart, and then find that the chart is wrong.

Ran a little large

Overall great seals. Very durable (I got a standard thickness). Only caveat is that the seal ran a little large for me. I had ordered a large and was right in the middle of the size range, but when it arrived, it was far too loose on my neck. I bought a medium and that is working great.

Good product. Excellent service

I find DGE to have excellent service. The seals they sell are good and the price is right. The manufacturer needs to re calibrate the sizing charts. I measure my wrists and neck before I re order and find the seal sizes they recommend to be a bit big for me. Fortunately DGE has been good about exchanges. DGX Reply: We have consulted with G-Dive and updated the sizing charts. Thank you for your input!

Great Neck Gasket for my Kayak Dry Top

Jan 21, 2018
The neck gasket for my kayak dry top appears to be of excellent quality. I had no trouble glueing it on and it fit the older dry top very well. It's a great value for the money.
