My silicone seals lay flat, and work well that way. The problem I see with tuck-in, would be twisting the neck or wrists might create channels.
I think getting a nice tuck might be a bit of a challenge as well.
I was also thinking that getting a nice tuck might be the most challenging part. But, assuming you get a good tuck, why do you think twisting would be any more likely to create channels? I was actually thinking that if wrist seals were tucked, so they went up the arm instead of down, they would be less on top of the part of my wrist where the tendons might stand out, so they would be less likely to get a channel.
They are orders of magnitude easier to don and way more comfortable than latex. No need for all that vet lube or worse, talc. I find a smear of E45 cream on the wrists helps them off.
I had been assuming I should keep using my talc bag even on silicone. So, that's wrong? Are they recommended to use some kind of lube? Or recommended to don with nothing at all? What is E45 cream?
I always have a squirt bottle of mixed water and baby shampoo in my dive bag. I use it for defog and wetsuit lube. Could I use a little bit of that for silicone seal lube? If so, do I put it on the seals or on my skin?
I've used both latex and silicone, and always wore all seals flat regardless of material. To do otherwise would mean less area for the seal, therefore more opportunity for leakage. If I had to fold a seal over (easily possible with the neck seal for some divers), I'd want to fold it out, not in.
Folding it out would mean there is no flat, cut edge laying against your skin. The edge of the seal would be a bowed out. With tucking it in, at least you would still have a flat, cut edge against your skin - even though it's on the inside.
I think having the flat, cut edge on the outside (i.e. not tucked in and laying flat) would be the best seal. But, it seems like tucked in would be second best and better than folded over on the outside. No?
Also, how do you figure having the seal tucked in versus out would make any difference to the area of the seal? It seems like that would only be the case if the sleeve were, for example, too short and the seal not positioned far enough up the arm. Otherwise, from wherever the seal touches the wrist, whether the seal goes towards the elbow or towards the hand, it should grip the same amount of surface area, shouldn't it? And, going towards the elbow would actually mean a tighter seal (since your arm gets fatter in that direction) plus (maybe) not being on top of the wrist tendons, so less likely to channel water if you really flex your hand.
Part of the reason I posted this question is because I remember reading a post or two a while back from someone on here that specifically said they wear their neck seal tucked in and it works fine. I know they weren't using neoprene (otherwise, it would not have been a remarkable statement whatsoever), but I don't remember whether they were using silicone or latex. I think they were using silicone, but I don't remember for sure.
I realize it probably sounds like I already made up my mind and asking the question was pointless. But, that's not it at all. I'm just trying to play Devil's Advocate and fully explore the idea before I decide whether I want to actually try it. I thought maybe someone would post something on the subject that I haven't heard of that makes it obvious it's a bad idea. Or maybe someone would post and say "I've been doing it that way for years and it works fine."
In the end, I have a feeling that getting a good tuck on a wrist seal, while wearing thick undergarments will be too tough and the question will be moot.
