Today I had a chance meeting with a woman who lives just a few blocks away…whose late husband invented the first modern zipper repair kit [there are many copycats] about 21 years ago.
Most zipper problems are easily solved with a simple replacement of the slider. How many of us have shipped an item back to the mfr, simply due 2 the fact that we have no experience w/ zipper repair? For $10 their "Outdoor Kit" is ideal for our packs, bags, tents etc.
I just thought our community ought to know about it! Their site is Zipper Rescue dot com.
It is such a simple no-brainer, as the more miles you hike, the more likelihood of grumpy zippers.
Ask for a "BPL discount".
I receive no kickback etc but I may get some seamstress work out of it if I'm lucky.
