Riri vs Crown zipper

[bigmanbigtruck]

Typically on stiff hides you're gonna see these waves develop. Not necessarily from folding them in a backpack or box, but just from movement and tension causing these bends. Softness of the zipper tape is going to force the teeth to take on that waviness. But these sliders are pretty good at routing the teeth together.

I've gotten used and relatively new LWs which also have this waviness but haven't run into difficulties pulling up the zipper. I have the same Crown zipper on multiple jackets as you do - they just glide through. Take care that you are getting the insertion pin to hit the bottom stop. You could try lubricating the teeth with wax or graphite and see if that helps.

The topic of this thread is close enough so I'll post my question here:
When we talk about leather jackets we usually discuss how a #10 zipper is ideal for the main zipper (at least in terms of max durability, but maybe overkill in terms of aesthetics). Or at least a #8 is highly recommended as the perfect compromise, especially if the leather is not absurdly thick and stiff.
For other zippers #5 seems to be the default? I'm talking about sleeve zippers, chest pocket zippers, handwarmer pocket zippers, d-pocket zippers, etc..
I'd like to use RiRi zippers for an upcoming jacket.
They don't have #5 it seems, only #4, #6 and #8.
#8 will be the main zipper, but what about the others?
Would you go #4 or #6 for the other zippers?

Six. Some companies claim #5 zippers as #6. Some #5 Military zips, are strong as hell. Those Mil. Zips tend to run bigger than the average #5

Many thanks that makes good sense! I have beeswax from leather working kit and I’ll wax the zipper as you guys have done.
