Nope. I wasn't even aware that any other manufacturer had a stretchable membrane suit.
Perhaps Hollis would like to send us one so we can put it through some paces.
My initial thoughts:
1. BARE claimed their SB to be "stretchable and breathable." Yes, it was stretchy, but after 300 dives I still could not tell you if it was, in fact, breathable. No, it never "fizzed," not even inflated... And the video I posted while looking for leaks (it was filled with air and pressurized) should have shown any "breathable" characteristics. The claim is bogus, if you ask me. I never found it to migrate air through the fabric in either direction - until it delaminated at the seams, of course... Then EVERYTHING migrated through it.
Yes, it stretched... Quite a bit... Which I believe was it's downfall. No, it didn't stretch as much as neoprene. For stretch, neoprene is still king... And with these "hyper-compressed" (BARE) or "crushed" (DUI) neoprenes having either zero or less than zero (!) buoyancy, I don't see a logical reason why to consider a trilaminate suit at all... Except maybe that they pack maybe 5lbs lighter - which might be a small advantage on an airplane.
The fact that Hollis does not claim that their FX100 is "breathable" doesn't surprise me. I don't think that BARE's really was either. I believe it was "marketing-speak."
The reason why they'd be so comfortable on the suface is simply because they're so lightweight and stretchy.
2. The BARE SB and the Hollis FX100 share that the waterproof part of their fabric is a stretchable polyurethane. I suspect that the problem with delamination that occurs in one suit will occur also in the other.
3. Hollis is an interesting company with interesting entries in the market. We LOVE their M1 mask and would be using it instead of a GoMask if we could get lights and cameras to attach to it. Their F1 fins are stellar, too, and have replaced our Scubapro Jets due to the better, more comfortable foot pocket that is much easier to wear for several hours at a shot. They're like a modern interpretation of the Jet fin, and the fact that they come with a 3-way adjustable spring heel (instead of having to add an aftermarket one that's not adjustable) is brilliant.
Should their FX100 be similar in philosophy, it'd be a great thing.
4. The Hollis FX100 appears to lack an internal fabric layer, making it a bilaminate fabric rather than a trilaminate fabric. This may help with delamination at the seams, but possibly at the sacrifice of easy sliding for donning and doffing. I'd be interested to try it out.
5. No plastic zip option (either TiZip or YKK) is missing one of the greatest drysuit innovations over the past few years, in my opinion. But that opinion isn't shared by everyone in the drysuit business, apparently - as the DUI CF200 isn't offered with a plastic zip option either. I think it should be available in all suits and would be disappointed to not have it if I owned an FX100.
6. I don't believe that the odd position of the shoulder dump would bother me. In fact, I might prefer it. Why do others like the "normal" bicep mount? I kinda find it gets in the way when doffing and have to be very careful.
7. Sock/overboot ("Rock Boot") option only would frustrate me. I much prefer a built-in boot with a deck sole for wet boat decks and docks. I like the faster don/doff and smaller profile for fins. Further, I'm not a fan of the propensity for puncture when walking around topside with the boots off. Just asking for a puncture, IMHO.
To me, the DUI Turbosole is the best drysuit boot made... But the SiTech flexible neoprene boot available in the BARE and SANTI suits is very good as well, and possibly more durable than the DUI Turbosole.
8. In looking at the Hollis lineup, I see a LOT of velcro being used in a lot of places that a zipper would work better - especially in pockets and over the entry zipper. Velcro has a short life expectancy in our line of work due to silt, sediment, and biomass in the water. In fact, some of us even cut the ankle straps off of our drysuits, as they get crudded up pretty quickly anyway.
9. What's with the top-of-thigh mounted pockets on some Hollis drysuits? That's a horrible place for pockets unless you're sitting - like in a pilot's fligbt suit or something... But in a drysuit, they work best in the slipstream of your armpits. They're also easier to access in their standard side position.
10. Internal D-rings in pockets are DIR-standard and great in caving. They work well for clipping off spools, lift bags and hand tools... But they get in the way of spare masks, wet notes, slates, non-snapped tools and spare parts during working dives. We cut them out of our suits so they don't cause an accidental drop.
Hollis pockets have internal D-rings. BARE pockets do not.
Some aftermarket pockets use a bungee loop rather than a D-ring, which seems less obtrusive when you're not using it. If I designed a pocket, that's probably what I'd use as a compromise between the two philosophies... But we'd probably cut them out, too, the first time it caused us to drop a bolt to a line cutter or whatever and had to go looking for it.
...Hollis, are you listening? Send me an FX100 so I can review it.
