Hi Troy,
Good question. The Drysuits come with a 2 yr warranty on manufacturers defects, this includes seams, seals, valves etc. I agree the website is a little short on detail.
Due to the construction, material, and cosmetics, these suits are by far some of the nicest I've seen in a long time. The seams are stitched, glued, and taped. They are very well put together. If you dont have any issues shortly after purchase, I wouldn't anticipate any issues down the road.
The Dynawave (neoprene) material is also unique because we compress the neoprene at the manufacturing level of the raw material, rather than compressing already made neoprene. This creates a more dense material resulting in a suit with greater resistance to pinhole leakage, and offers greater flexibility. (flexibility is one of the comforts lost when compressing neoprene). the Webtex material on the inside offers thermal protection but also creates thermal energy from the friction of your body and the material. This means you can wear less undergarments than if you were in some other suits.
Latex collar and cuff seals create excellent sealing with customizable cutting rings.
The vulcanized boots are comfortable, durable, good traction, low profile and have a fin strap retainer on the back.
Just above the boots you have vulcanized shin and knee protection. This is a high wear area especially for photographers.
The suits all come with hi end Si-tech valves (360* swivelling inflator valve), suspenders, butterfly LP hose, latex neck and wrist seals and a fully dry storage bag.
Troy, there are many suits out there. Some better than others, this one is definitely in the better category. It is extremely well designed and built. Utilizing the best materials, resulting in a stylish yet very durable and comfortable suit.
Where are you diving? Have you seen them first hand? Perhaps I can point you in the direction of a Mares stocking drysuit dealer to check them out.
I hope this helps answer your questions and alleviate any concerns.
Best regards,
