I own one. I disagree about the factory pockets. I have the velcro bellows pockets, and they work quite well. They are better constructed and easier to use than the pockets on my X-shorts.
The suspenders are overpriced and do not work very well.
The suit is very durable. I installed a P-valve in it and punching through the leg material was a chore. This durability adds a little extra weight when compared to some other trilam drysuit offerings.
The chest zipper has been easy to use and has made getting in and out of the suit a solo affair, instead of having to ask your buddy to zip you up like with my previous suit. This was the key feature for me.
The ATR feature (Automatic Torso Recoil) makes putting the suit on or taking it off pretty easy and removes the need for a strap of some sort to deal with excess torso material. The downside to the ATR system is that if you flood the suit (or have a P-valve "malfunction") it is difficult to dry that area behind the stretchy neoprene. The rest of the trilam suit dries pretty fast.
The built in leg gators work OK, but still allow excess gas to migrate to the legs if you are not diligent.
The default bicep dump valve location requires a slightly different technique than a shoulder mounted one. A muscle flexing pose dumps gas better than just lifting the arm.
The latex wrist seals have done a much better job of keeping my wrists dry than the neoprene seals on my old drysuit. The wrist seals seem to have developed some surface cracking a little sooner than I expected (despite applying 303 Protectant regularly). I chose the neoprene neck seal, and it has worked well.
I chose the attached boots in size XL (USA 10), despite typically wearing a 10.5 or 11 street shoe. With two pairs of wool socks, they fit nicely. I can still use XL Jet fins with the suit, but the are hard to take off. If I use Turtle Fins, the fit isn't as good, but it is easy to don and doff the fins.
I'm 6'2 and 205lbs and the stock XL fits me pretty well. I think the Bare Trilam HD Tech is a sold option and a great value compared to other trilam suits that cost considerably more.
