Just the cost of the Zip Seals alone would make me second-guess buying a DUI suit.
This is where purchasing from DRIS is a huge benefit. For $200 above the cost of the Premium or Platinum Lifetime Guarantee, DRIS will replace a full set of zip seals each year if needed. The neck seal is $138 and the wrist seals are $118, so you see where the benefit is HUGE! Also...they ship the first replacement set to you with your suit, so you can carry them with you and never miss a dive because of a ripped seal.
With that said...these seals are not all that fragile if you take care of them. I had one set for 3 years with a couple hundred dives that I finally replaced due to age.
