I just wanted to take a few minutes and provide my personal feedback on my Seaskin Nova and options now that I've had it a little while and have over 20 dives in it for other folks to reference when they order.

I'm a fairly new diver (about 150 dives), no prior drysuit experience. I ordered in Jan 2025, got it in April 2025, did the SSI course with it, and have been diving mostly at a quarry with a few NC coast dives the past 6 months. Nearly of those have been in temps from the mid 60s - mid 70s F (or roughly 17-25 C), with a thin undergarment and occasionally a second thin top layer. I look forward to winter diving with this and wanted to make sure I was very comfortable diving it with just the base layer before adding thick undergarments.

Overall: I love it, the fit is fantastic (except for one item I'll cover below), it's comfortable, easy to don and doff, light but durable, I've had no leaks other than a fingernail hole in a wrist seal (my fault). Here are the options I ordered (excluding colors which were black, blue, and dark grey stitching, see pic below). I did gain some weight (10-15 lbs) between Jan when I ordered and now, but I still fit comfortably, at least without thicker undergarments.

SeaSkin Tech Base: very comfortable, nice weight for warm waters.

Seaskin 150 Undersuit: I haven't used this much yet, will provide feedback later.

SiTech Quick Neck Seal: Very comfortable, easy to change. I took 2 rings off and it fits and seals great. They were out of the tool when I ordered, but mailed me one later. I also ordered an extra seal.

Warm Simple Neck: I got this mostly so that it cleans up the look and to help with making sure my harness webbing doesn't accidentally damage the exposed neck seal. It does a good job at these, not sure if adds any warmth but I like it.

SiTech Oval Cuff Rings/Seals: I like the low profile, very easy to change seals (I did tear one with my finger nail). I don't plan to dive with dry gloves any time soon, so this works well for me. I also ordered 2 extra seals.

Telescoping Torso: A must for me. I would struggle a lot to get my head back out and take it off without this. I know this from when I forgot to unbuckle it and got stuck trying to get out.

Dry zip cover: I like this for storage and cleaning, it makes it easier than using the main zipper and also looks cleaner.

SiTech Trigon Pee Valve and pee valve hose tidy. I really like this feature. it's easy to use, low profile. I did replace the connecto with quick disconnects to make things even easier. The tidy option helps keep it from getting in the way of my leg when donning.

Move Dump to DIR: It's in the right location for me to reach it if needed (I dive with it open) and it's the right spot to slightly lift the left shoulder when I need to vent.

40mm Braces: I leave the bottom half of my drysuit on during surface intervals and walk around with the top off. These wide suspenders make that very comfortable. I did modify these slightly by folding the end over and taping them with a nylon repair tape. This makes a thick end that won't pull through the buckle which did happen when it was loose (not while wearing).

Elastic Back Panel: This might be unnecessary. I don't really notice it and the waist straps of the back plate webbing cinch that area in to me when I have it on, so I'd probably skip it next time.

Expedition Pockets: I was worried these might be too big but they are great. They do have an inside thin pocket that is the same width and depth but for narrow items (good for wet notes) and the main pocket, as well as a small zipped pocket on the flap. There are two large loop bungees and one small loop bungees in main pocket as well as 2 medium sized bungee loops in the zippered flap. I found the large bungees in the main pocket got tangled pretty easily so I slide some heat shrink over them to make the loop part smaller. The inside narrow pockets also do not have grommets to drain so I added two holes in them very carefully in the same place as the main pocket grommets using a soldering pencil so water can drain out from the bottom. I keep wet notes and spare mask on my right with extra room, and on my left I can fit a divevolk camera and SMB with spool no problem.

Custom Feature: I asked them for a name patch but to sew it on velcro square so I could remove it and swap it with other fun patches. See photo for an NC patch I put on.

Tech Boots: This is the only issue I had with the suit. I do not blame Seaskin and they have been very helpful. My size falls right between XL and XXL. I wish I had thought more about this and would have requested to pay for a pair of them to try first before completing the order. In my order I have down that I'm a Euro 44/45 with a 28cm foot length. I have a slightly wide foot, so the 44/45 usually gives me better room. The XL boot they use is a 43/44 and the XXL is a 45/46. Logically, they put on the XXL since too big is better than too small. And it was just way too big. I had about 1.5cm of extra space in the toe and the ankle was huge. I temporarily dealt with this using gaiters, triple insoles, double socks, foam in the toes, but it wasn't great and the fit was sloppy. I talked with them about it and they volunteered to make it right. I asked them to ship me a pair of XLs so I could try them, and then if they fit, I'd take care of installation. They agreed without hesitation and shipped me the XLs at no charge. I've since swapped over to the XLs and they feel wonderful. I am still using a thick wool insole since the insole that comes with them is very thin rubber, but no need for gaiters and they finally feel right. If anyone is curious, they use Beaver Sports D4 4mm drysuit boots.

Overall I felt communication with SeaSkin was great (email sometimes took a while, but calls always got answered). They were excellent about shipping me the neck seal tool later and a new set of boots all at no cost. I haven't felt like I'm missing any features I'd want, and I think the only one I would skip if were to order again is the elastic back panel.

Thank you to all of you on this thread for helping me research and order this!

The warm neck is to prevent flushing at the bottom of a hood, if you're not wearing a hood there will be no benefit except for the seal protection as you mentioned
 
The inside narrow pockets also do not have grommets to drain so I added two holes in them very carefully in the same place as the main pocket grommets using a soldering pencil so water can drain out from the bottom.
I did the same, but latest iteration have gromets. JFYI.
 
Am planning on getting a drysuit and was thinking of a trilam Seaskin. How does the quality compare to some of the other more affordable MTM drysuits like Northern Diver, Otter etc?
Most reviews seem to be from recreational divers, I'm a tech diver diving a CM rebreather (Choptima) and usually dive wrecks penetrating and running line. Is the drysuit strong enough to avoid tears from rubbing against walls and doors? Seems that most people recommend against getting the knee and elbow pads, but should I get them since I'm in wrecks to further protect and avoid tears?
Move valve to DIR?
Otherwise, was going to get the telescopic torso, trigon P valve, hose tidy, Sitech neck and oval wrist seals, wider braces, 2 expedition pockets and tech boots.
Any comments on my choices?
Thanks for all the help

I haveexperience with Northern Diver and Seadkin. 2 different suits, neoprene and trilam. I prefer the Seaskin because it was M2M. I do a little wreck and a lot of quarry / oyster diving. My suit is never "clean" when I'm done a dive. I got all the reinforcements and don't regret it. I think it's holding up great.

I've seen Otter irl and it looked like a really well made suit. There's lots of great suits out there, maybe even slightly "better" looking than Seaskin, but I'm dry on every dive (save human error of some sort).

I did not move the valve, I don't know which is better, but I do have to roll my shoulder up slightly when wanting to vent. Unless you plan on being in perfect trim all the time I can't see an advantage any which way. I think you'll get used to either or.

I got everything else you have except boots and I'm very happy. Good luck, no matter what you get you'll wonder what if, but it'll all work just fine. If I ordered 3 suits I'd get them made slightly different and wouldn't know until I tried all 3 which I liked the best...

I normally say no reinforcements as they make repair harder but if you will regularly be diving in pokey situations they can cut down on repairs, your call but assess where you do make contact and see if the extra protection is actually there. I always go with neoprene socks so I can choose which boots I want to use add the fact that it’s not an option for me anyway since they don’t offer boots in anything but little kid size feet ;)

I don’t have a real opinion about pockets but if you need them go for it, I only get one and it’s zippered, never needed bigger.

Good choice on the seal system and trigon.
 
If I were in for a new suit, I'd forgo on tech boots and go with socks. Those soles are way too thin for anything but a smooth surfaces. I do disagree with lexvil on pockets. No one ever said that they have too much pocket space.
I don't dive wrecks, but I do dive river with rocks quite similar to those sharp ones seen in a lot of caves and so far had no issues without protection. I do mind not to drag myself against the rocks though.
 
I just finished reading the entire thread a second time and determined to order my first drysuit very soon, as I am going to start Tec training in a few months. Big thanks to @stuartv for starting the thread and all others who have contributed. I made my mind up about most of my options but not sure about a couple

1. Extra Allowance for Thicker Suits
The coldest water temps in my area are about 7C in winter. My instructor told me he never used his BZ420X as it is too hot for him for the conditions in our country. An avatar 901 and wool base layers are enough for him. I am planning on getting the same undergarment or a kwark navy and will layer wool accordingly. After layering, would the suit feel too tight without the extra allowance or is the default cut enough? I read some had problems wearing their seaskin 250's with the default cut, and I don't know how the thickness of my current choice compares to 250g thinsulate.

2. Small Wrist Seals
I have quite thin wrists (15.5 cm circumference). I once used a drysuit at my dive club which had the qcs with default latex seals, the seals were a bit loose and I had to wear cut bicycle inner tubes over the seals to prevent leaks :D. I saw on the seaskin website that the silicone seals come in two sizes, small and standard. The small is suitable for wrists in the 13-15 cm range and the standard is suitable for 16cm and up. My measurements fall right between these two, which option should I pick? Should I just work forearms to get manlier wrists🤔

other than these two, I am almost certain about the following options:
- Grey Body
- Black Arms
- Orange zipper cover (I really liked how @BillaVista 's suit looked and after emailing seaskin, learned that they can make orange covers and arms upon request:yeahbaby:)
- Fully telescopic torso
- Plastic Zip
- Trigon P-Valve
- Quick Neck
- Simple Warm Neck
- Kubi dry cuff system and corresponding glove side
- DIR dump position
- SI Tech Valves
- Comfort Patch
- Compressed neoprene socks
- Kevlar knee pads (no writing)
- 40 mm braces
- 2 expedition pockets
- Trilobite on right pocket ? (not quite sure about this, any better placements ?)

I think your best bet is to order with standard size silicone seals but order an extra small set with the suit. I’ve never needed the extra room but also don’t use fluffy hollow fill type insulation. You’ll be happy with the suit, maybe even with the Kubi’s ;)

Suit build looks great. Get standard sized wrist seals and a spare set in the smaller size. They're only there for when you cut a glove. I think you'll like not having circulation cut off from too tight of a wrist seal. I don't even have mine in the suit anymore. With Kubi you can add/remove/change the seal at your leisure and it's not not necessary if you're not grabbing onto razor blades. The standard glove that come with the Kubi system are meh. They're thin and flimsy. I went with Showa 660 because they have shorter fingers in the XL size and can accommodate thicker under gloves without getting floppy fingertips.
