Latex seals are amazingly tough. You have to use "some" care when putting on, and removing the suit, but other than that..... You will get instructions, including care, when you buy your suit. It is recommended that you clean the seals with a little soap and water after a number of uses, and dry the suit properly. It's a good idea to dust the seals before storing the suit, but this just makes it easier the next time you have to use it. You just want to avoid putting a nick in the edge of the seal, as this will cause it to tear. But I would'nt be too concerned about them being fragile, they can take a pretty good working out. Try going on the DUI site, they have the manuals online, and you can read about them before you make a decision.
