on buying an
OS Systems Drysuit!
You have just invested in one of the finest diving suit available today. In order to fully realize the benefits of your suit, we have prepared a few notes on use and care. This information is not intended to replace a Drysuit Techniques Course which should be available at your local dive shop.
In order to learn to dive safely, you spent approximately forty hours in a scuba class which taught you the safe use of a tank, regulator and buoyancy control device. You should now spend a few more hours to properly learn the use of a variable volume drysuit.
Take your time … learn your suit… perform the recommended cleaning and maintenance of the system… and your OS Systems drysuit will provide you with years of dry diving pleasure.
It is important to remember that your suit is designed for environmental protection only and is not to be used for buoyancy control.
It is also very important that you properly weight yourself for neutral buoyancy so that when you expel all the excess air from the suit you do not sink.
If you are an experienced drysuit diver, make a few training dives to familiarize yourself with the system and to learn how much air and weight you need for a comfortable dive. If this is your first drysuit or are new to a shell style suit, take a drysuit class from your local training facility or make at least 10 to 12 training dives with a competent, trained drysuit instructor to become completely comfortable with your drysuit diving skills.
DO NOT attempt to make normal "Fun" dives until you are totally familiar with your new suit and confident in your new diving skills.
Your shell is primarily nylon with a waterproofing layer physically bonded to the inside. After use, the material should be rinsed in clean, fresh water. The dirt or grime can be washed off with a mild soap and a soft brush. The inside of the suit should be cleaned also, to remove perspiration and body oils. DO NOT hang your suit in the sun to dry as this damages the material and causes leaks. Allow the shell to air dry, perform seal and zipper maintenance and roll the suit for storage.
To roll the suit, lay it with the zipper open and facing the floor. Begin rolling from the feet towards the neck. When your suit is rolled up to the neck, fold the arms/zipper over the roll and the suit is ready to be stored in the suit bag (optional).
OS Systems seals are made to exacting specifications of the finest materials available, but are still subject to deterioration if not cared for as follows:
New neck or wrist seals may feel tight or a little restrictive at first but will relax with use. It is possible to pre stretch your seals by inserting a soda bottle into the neck and/or wrists while soaking the rubber with liquid silicone. This should make the seals feel more comfortable. Contact your dealer if you still need any additional sizing or trimming.
While operating the zipper, care should be taken to insure that no dirt or foreign material is trapped at the sealing surface that could cause a leak or dislodge a tooth. Zipper teeth are to be cleaned regularly using a soft bristle brush and mild soap.
Store the zipper completely open and do not close it until the suit is on and ready to use. Sliders should operate smoothly and easily. If binding does occur STOP! DO NOT FORCE THE SLIDER!! Reopen the zipper; inspect; clean and lubricate as necessary.
The right undergarment with a proper fit is the key to warm diving and buoyancy control. If your Undies are too large, you should consider having them tailored to remove excess material. Don't use cotton (T-shirt, sweats, shorts, etc.) under your garment. The cotton material does not wick the moisture away from your skin and you will feel a chill as you perspire.
Your undergarments will need periodic cleaning to remove perspiration and body oils. You can machine wash with regular laundry soap (no bleach) and hang or tumble dry on low/cool setting. Air drying is the preferred method since the dryer causes the fleece material to "Pill" faster, plus the warmth of the machine tends to tighten the weave of the fabric temporarily making the undergarment tighter fitting.
