Bio-Seal Drysuit Neck Seal Helper

Used under my ScubaPro Everdry 4 drysuit (v 2018). Helped a ton with leakage around the neck seal. Users should know it's easy to get on, do take the time to make sure it's flat and fold-free and that your neck seal sits on it properly. Once that's done, though, it stays in place the whole dive and works great. I always use with a hood so I can't speak to how it works without.

This thing is amazing!!!! I have a Scubapro Everdry4 drysuit, which uses neoprene wrist and neck seals. I've done eight dives on this suit and prior to using the Bio-Seal I had a tough time getting the neck to make a good seal. I always seemed to get at least a trickle of water down my neck anytime I moved my head. On one dive the leak was so bad that my undergarments were completely soaked. I decided to give the Bio-Seal a try and it worked wonders! I expected it to alleviate the trickle problem but I didn't expect it to completely seal. But it did!As an added bonus, the texture of the Bio-Seal makes it easier to fold under the neoprene neck seal of my drysuit. Before, it was always a pain to get it folded under perfectly. For whatever reason, it was really easy to get it folded under and perfectly flat with the Bio-Seal on. The instructions say to put the drysuit on first and then put the Bio-Seal on, but the collar on my Everdry4 suit is too tall to allow this, so I put the Bio-Seal on first and it worked just fine.I can't say that the Bio-Seal will work wonders for everyone, but for me it allows me to dive and remain bone-dry in my drysuit, something I could never achieve before.

I would like to give this 4.5 stars, but that's not an option. I just got dry suit certified, and my neck is very thin. The water would rush in to the suit, and pool down around my feet. This seal helped to sharply reduce the amount of leakage, although I guess that eliminating it entirely isn't possible. Just the same, the difference in the amount of water that came through before I used this product was huge. Great product, and I am now considering the wrist seals.

My flabby neck wasn’t allowing for the best seal in my dry suit! Pricey, but better than a new seal and it’s probably just my neck anyway.😅

I have a thin neck. My dry suit neck seal would always leak a little. My chest was always wet when I took my suit off.This neck seal works great. I am now nice and dry when I take my suit off. Great Product!!

Got soaking wet. This is an overpriced useless piece of garbage.

Easy to put on and use. Have used on numerous dives.Product shipped very fast and had in time for weekend dives.The bottle it came in was damaged in shipment but the product was fine so that wasn't a big deal.

Works good for sealing up a leaking neck damn after being in the water for extended bottom times working.
