I learned something today from Kevin Brickley, our 2019 Eliel kit chairman. He said the best way to wash your jersey is to zip it up fully and turn inside out for washing. This really protects the zipper from any kind of damage during washing (I know of a few folks who have had their zippers replaced - Eliel will do it for free). Dave Dooley also shared his trick of keeping the bottom ~1/4 of the jersey zipped most of the time, so you pull it over your head when taking off and putting on. This also saves stress on the zipper especially for those with the race (Rincon) styles where you need to stretch a wee bit to zip up for the snug fit. I have had minor issues on my 2019 jerseys where the zipper came apart, but always recovered without a replacement so far. YMMV.
Good advice! Thank you for the tip Karlos.
