Neoprene vs. scuba knit, how do they compare?

[Mermaid Momo]

Hi all! I'm planning on doing a second go at a partial tail but I can't decide whether to go with neoprene or scuba knit. Does anyone on the forum have experience with scuba knit? How thick is it? It caught my attention since a few tailmakers use it in their partial tails and researching it, it is a lot cheaper per yard than neoprene is but how does it hold up?

I have two scuba knit tails. Haven't swam in them much, but I have painted them and sewn them!

It is very flowy and soft and easily flops. It sews like you're going through a t-shirt, really. Not too thick at all, and would certainly show the lines/ridges of a monofin. But it takes Lumiere very nicely. I would go with the neoprene if you have the funds; it'll look more realistic and last longer!

My sequin tail has a scuba knit base. It's about .5 mm thick and goes through the sewing machine easily. I prefer it to neoprene because it is less floaty and cheaper, yet much thicker than spandex. I know several others on here who used it as a base for their sequin tails but don't know about anyone who has used it with silicone. Be careful where you buy from though because it seems different stores have different opinions about what scuba knit is. I intially bought mine from fabric.com but when I got it, it wasn't what I was looking for. Too thin, and more like spandex. Then I bought what was labeled neoprene scuba from fabric warehouse direct, and that was what I wanted and used.

Thank you both!
Do you think it would hold up under silicone? how warm would you say it is and how much stretch does it have?

I think it'll hold up under silicone. Its not as warm as neoprene obviously because its only .5mm but I was able to wear mine all day at GAC during Mermania without getting cold, which says somthing because I'm a freeze baby. I think Mermaid Mazu is making a silicone hybrid one with it now that I have had a chance to browse the forums more.

Thank you! I think I'll end up ordering it It's thick enough so that if I lay it down it won't fly up if I say took something sticky to it right? (if that makes sense) because I'm going to be piping the silicone on top of the two tail skin halves and don't want to start piping and find out it likes to roll up with the silicone tubing.

[Mermaid Aria]

It shouldn't do that it's thick enough. Let me know how it works out

Can do! Thank you so much for your help! Hopefully my new tail will be complete by the end of March!

Hi momo after much debate trying to figure out exactly what I use as my base for my hybrids, it is in fact scuba knit. I personally really like it. It holds up nicely under silicone caulk, I'm sure it would under the good stuff too.

I've been thinking of a scuba knit tail for awhile...

Is it warmer than spandex? And does it have the same amount of stretch?

[mermaid mazu]

It's a lot thicker than spandex so it is warmer. It has good stretch but maybe not quite as much as spandex

[Mermaid Jaffa]

Thanks! I ordered a sample. I don't swim in ocean but the pool sometimes is cold, even in winter!

I ordered 2 yards last week sadly I'm not sure if it shipped at all since i never got a shipping confirmation

Hang on and I'll see if I can find a link to the company I always use. They are really fast.

That's who I ordered from. Do they usually send a tracking number because I haven't gotten one yet.

[mermaid mazu]

I've always ordered through ebay (which I now see is cheaper straight from their site) so ebay has always sent me notification not them. I've ordered from them on 4 occasions though and always get it in a couple of weeks

I'll update this later with a detailed overview of neoprene vs. scuba knit, what are some things you'd like me to focus on to compare and contrast?
