Zippers


Zipper Definitions:



YKK: YKK makes approximately 90% of all zippers in the world!

Sizes: #3 is a thin lightweight zipper that is used on most of our ultralight gear. #5 is a larger more durable zipper that can be used in areas that get more stress.

Continuous Coil Zipper Tape: This type of zipper must be sewn shut on at least one end. The two sides cannot completely separate once the zipper pull is put on it. These are used for tent doors, sleeping bags, armpit zippers, ankle zippers and so on. They can be cut to any length. You can also install two zipper pulls such that they open from the center and the tape would be sewn shut at both ends. Coil zippers are lighter weight than tooth style zippers.

Zipper Sliders: These are used on continuous coil zipper tape. A "reverse" slider has the pull tab on the back side, which would be the smooth side of the zipper tape. A "double pull" slider has pull tabs on both sides. Coil zipper tape has a ridge on the front and is smooth on the back. The ridge has to be inserted the correct direction into the grooves on the sides of the zipper pull.

The most common cause of zipper failure is if the metal on the zipper sliders wears down over time. They are easy to replace! Put both sides of the zipper tape a tiny bit into the zipper pull, then "push" the zipper pull onto the tape with your index finger. It takes some practice at first.

Separating Zipper: This type of zipper has a special slider on it such that one side of the zipper tape inserts with a pin. The two halves can come completely apart, like you would need on a jacket. The top of the zipper tape can be trimmed down, but you can't cut off the pin at the bottom.

Two-Way Separating Zipper: This type of zipper has two special sliders installed that allow it to open from either end, and also the two sides can come apart. These are most commonly used on joining sleeping bags, sleeping bags that allow you to vent at the foot, and for longer jackets that need to open from the top and bottom for venting. YKK does not make a #3 size two-way separating zipper. 

Uretek / Waterproof: This type of zipper has a waterproof coating on the back. Normally the smooth shiny "back" is faced outwards, which means you need a "reverse" zipper slider such that the pull tab is on the back. Double pull sliders also work. Separating Uretek zippers come with a special reverse slider already installed.


#3 Continuous Coil Zipper Tape - NOT WATERPROOF



This zipper tape comes on a big spool and is sold by the foot. This type of zipper must be sewn shut on at least on end and can't fully separate once a slider is installed. It is used for applications like sleeping bags, tent doorways, etc where at least one end of the zipper is sewn shut. Zipper sliders are not included. You will need one or more #3 sliders sold below.

Weight: .33 ounces per yard (10.2 grams per meter)

Price: $.40 per foot (30.5 cm)

#3 Uretek Continuous Coil Zipper Tape - WATERPROOF



This is the same as above, except with a shiny waterproof coating on one side. It is useful for applications like armpit zippers, or for waterproof bags like our belt pouches or multi-pack. You will need one or more #3 sliders sold below.

Weight: .42 ounces per yard (13 grams per meter)

Price: $1.45 per foot (30.5 cm)

#5 Uretek Matte Black Continuous Coil Zipper Tape - WATERPROOF



This heavier duty #5 Uretek waterproof zipper is useful on products that require more durability, like backpack pockets. It is matte black color rather than shiny. You will need one or more #5 zipper sliders.

Weight: .8 ounces per yard (25 grams per meter)

Price: $1.95 per foot (30.5 cm)

#3 Double Pull Zipper Slider



These sliders will fit both the normal and waterproof #3 continuous coil zipper tape shown above. They have a pull tab on both sides, so they can be accessed from the inside or outside of your gear (for example on a tent doorway or a sleeping bag).

To install these on to the zipper tape, insert both sides of the tape part way into the slider, and then "push" the slider on to the tape with your index finger. It is tricky at first but easy when you get the hang of it! Pay attention to which way the groove on the side of the slider is facing relative to the zipper tape. They can be inserted on to either end of the zipper tape.

Weight: .08 ounces (2.3 grams) each

Price: $.35 each

#3 Reverse Zipper Slider



These sliders have a single pull tab which would be on the "back" of the tape (the shiny / smooth side of the waterproof zipper tape above). You will want the shiny side facing out on your project. Use these when you only need to access the zipper from the outside (for example our our belt pouches or multi-pack).

Weight: .06 ounces (1.7 grams) each

Price: $.35 each

#5 Reverse Zipper Slider



These sliders have a single pull tab which would be on the "back" of the tape (the smooth side of the #5 waterproof tape above).  Matte black color.

#5 Two-Way Separating Zipper - NOT WATERPROOF



These are bigger/heavier #5 zippers. They have two zipper pulls and open from both the top and the bottom. They are separating, meaning the two sides come apart like on a jacket.
