Waterproof Zipper Lubrication...
Waterproof zippers are much more precise than regular zippers, with closer tolerances. Occasional lubrication hugely reduces slider drag. Makes zipping much easier. (You'll feel a small difference in 'slider pull' everyday in ease-of-use and off-and-on convenience.)
Teflon "chain saver" is the best way to make waterproof zips work faster and easier. This lubricant is applied to every Aerostich waterproof zipper during manufacturing. We experimented with other lubricants -- this one is the best. (Formerly labeled as 'Teflon Multi-Use Lubricant' by its manufacturer. Why did the name change?...formula is exactly the same.)
One quick zipper application provides months of lubricant effect, even if exposed to occasional rain. So ignore the packaging. (Yeah, it is also excellent for levers, cables, latches...and even chains.) A little bit goes a long way.
Modern zippers are precisely engineered micro-machines which usually work trouble free for year and years. When problems occur they are almost always caused by mis-uses like over-forcing a jammed slider, though sometimes dirt contamination, direct impacts or long wear also cause failures.
If you ride a lot it's a good idea to always carry an emergency replacement slider like this: FixnZip -- especially on day long rides and multi-day trips. Leave one of these at the bottom of any pocket and it will always be there when you (...or a riding buddy) need it.
Aerostich garments contain two different zipper types: Nylon molded-teeth with locking sliders for the main openings, pant-to-jacket connectors, and wrist gussets -- and a nylon coil style with non-locking sliders for vents and pockets. Both divide further into water-resistant and traditional styles. Most Aerostich zippers now are the water-resistant type.
These highly water-resistant zippers feature miniature gasketing systems, ultra-closely dimensioned internal tolerances, and vinyl covered knit nylon 'tapes' on either side of the zipper's teeth or coils. These specialized zippers come pre-lubricated and this lubricant should be renewed at least annually. We like this stuff: Teflon Multi-Use Lubricant because it lasts a long time, doesn't leave greasy residue, and doesn't collect dirt. Single-use lubricant packages are included with all new Aerostich garments, and are available separately here: Aerostich Single-use Zipper Lubricant
If fabric jams the slider, don't pull harder without examining the area first. Sometimes it's best to try and pull the fabric outward from the jam and other times it's better to carefully force the slider backward down the zipper.
If a zipper jams at the same place more than once, try creasing the adjacent fabric to help it ‘remember’ to stay away from the zipper’s sider better. And practice using one finger to help guide the fabric away, or pull the slider past this area with a slight upward or outward vector so the adjacent fabric is flattened away from the slider.
Aerostich toothed-zipper sliders all lock in place whenever the slider's handle is lying flat. Pulling the handle upward releases a spring-tensioned internal locking pin, allowing slider movement. If a zipper slider moves when it's not supposed to the slider’s handle is being pulled slightly upward, usually by pressure from adjacent fabric
