My Kokatat came with instructions to store with the zipper closed. It's a plastic zipper. Since we seem to have conflicting advice, I looked it up on their site, and there were some interesting tidbits:
- Metal zippers should be stored partially closed with the zipper slide about 2 inches open
- Plastic zippers should be stored entirely closed
- Store either hanging or loosely rolled
- McNett Zip Tech lubricant for plastic zippers
- Paraffin or beeswax lubricant for metal zippers
- 303 Protectant every 4-6 weeks on latex gaskets

When washing, always follow sewn-in care instructions. With dry suits and dry tops Kokatat recommends using cold water, delicate cycle, gentle liquid soap, with no bleach or harsh chemicals, and high water volume, in a front loading machine. Rinse well (which may mean running it through a second time, inside out with no soap OR use a cold shower). Line dry.
Gasket care and repair
Latex gaskets need to be treated every 4–6 weeks to prevent drying and cracking. Kokatat recommends 303 Protectant. Small tears or holes in the gasket may be repaired with Aquaseal. Replacement gaskets and kits are available from your dealer or directly from Kokatat. Kokatat (and some dealers) will replace gaskets for a reasonable charge. Kokatat will replace gaskets and socks on Kokatat garments only. Please contact Customer Service at 800.225.9749 to obtain an Return Authorization Number (RA#).
Zipper information and care
The zipper is one of the most sensitive components of your drysuit. Treat it carefully. The most common causes of zipper leakage are failure to close the zipper firmly, or dirt in the zipper teeth or closing end.
1. Pull the zipper in a straight line, in a smooth and even motion. Avoid yanking or pulling to the side. Have another person help you if you cannot easily reach any part of the zipper. Be especially gentle in colder air and water temperatures.
2. Never force a jammed zipper. Unzip, examine the jammed point for obstruction or damage, then carefully try again. Zipping over a piece of dirt or underclothes can derail the teeth and ruin the zipper. (Continued on the other side.) Rev.: June 5, 2015
3. The zipper is most vulnerable to damage when you are getting in and out of your suit. Be sure the zipper is open completely, and try not to put force on the ends that could tear the zipper apart.
4. Keep sand and dirt out of the teeth and the closing end of the zipper. Clean the zipper occasionally with mild soap, water and a toothbrush. Lubricate occasionally with a light coat of paraffin, beeswax for metal tooth zippers. For plastic water tight zippers, a dab of McNett Zip Tech™ Semi-Solid Zipper Lubricant in the closing end improves sealing.
5. Dry suits should be stored in a clean, dry environment. Metal tooth zippers
should be partially closed with the zipper slide left about 2 inches open. This will help alleviate pressure on the sealing elements. Plastic water tight zippers should be stored in the entirely closed position. Store either hanging or loosely rolled. Broken zippers cannot be repaired but can be replaced. This work may be performed only by Kokatat at our factory; if you feel your zipper has been damaged, please contact Customer Service at 800.225.9749 to obtain a Return Authorization Number (RA#).
Durable Water Repellent (DWR) prevents liquid from building up on your garment’s outer layer which can make you feel damp and clammy (“wetting out”). Regular wear and tear, exposure to dirt, detergents and other impurities causes DWR to wear off over time, but the good news is that it can be restored. The effective life of the DWR depends upon how the garment is cared for, and how rigorously it is used. The most effective way to maintain the garment’s water and stain repellency is to rinse it and let
it drip dry (washing helps, and if it’s not a gasketed or a coated fabric, then it can be put in the dryer). DWR is not what makes a garment waterproof - it’s a treatment applied to the face fabric that keeps water beading on the outer surface rather than soaking into it. Eventually the DWR will wear out. There are many aftermarket DWR renewal treatments available from your local dealer.
