quality zip system Ykk


January 15, 2020 1 Comment

High-quality accessories typically come with high-quality zippers.  When researching components to develop the SUB45, we analyzed this topic extensively and happily settled on YKK zippers, considered to be the best zippers available in the marketplace.  We also agreed to pay twice the cost of the second-best alternative...  We are glad we did!

Not that they do not binge-watch...

Netflix at times but FITLY Running Packs users are on the opposite side of the couch potatoes spectrum.  We find them tackling all kinds of terrains in all kinds of weather at any time of the day in any season. Some of the pictures we receive project a deep sense of adventure and a “whatever it takes“ attitude. 

Components going through such treatment will collect dirt, salt, dust, sand and all kinds of particles.  Add water, lack of use at times and any zipper will jam if not properly maintained. 

If you google “unstick zipper”, you’ll find a lot of home remedies.  

Be nice!  Zippers are like tangled ropes, do not force your way out of it.  Here is a good video to watch as a starting point.  Good Advice: after washing it, exert pulling/pushing force with plier on the slider if the zipper is locked into place solidly, not the pull tab.  The pulling angle will be parallel to the chain and more effective than the angled pull tab.

Once unstuck, wash the area carefully with a toothbrush and lubricate the zipper.

YKK’s official care and maintenance:  Apply paraffin or the lubricating spray ZIPPYCOOLto the front and backside of the elements and move the slider up and down several times to work in the lubricant and make the slider work smoothly.

You can also use organic lubricants such as wax, oil or grease. 

They may perform well but could behave variably at different temperatures (slippy or gooey) as they get hotter or colder.  Powdered graphite or crayons are common remedies.  Some also use Teflon silicone lubricant, silicone-free products such as McNett’s ZipTech.  We are not associated with nor endorse any of them...  Find the one that works for you! 

You own the best zippers available. With proper maintenance, your zippers will perform for decades and outlast any other component!

Pour avoir testé beaucoup de sac à dos, la qualité des zip est hyper importante. Après 1 an de test sur le Fitly et l’avoir mis à rude épreuve, les zip tiennent encore le choc. Beau produit de qualité.
