Installing pit zips in raincoat ?

[Grassymike]

Has anyone ever done this ? I have a 3l raincoat from north 40 outfitters that has no pit zips, I would like to install some. Wondering how hard this would be to accomplish and what zippers would be best to use. thoughts ?

I've never attempted pit zips, but I have installed zippers on clothing. I don't think it would be too difficult, you'll just have to be brave enough to make some cuts in your raincoat . Here is a good example: https://backpackinglight.com/forums/topic/27921/

My rain jacket's pit zips look like waterproof zippers. I like that there are two sliders so that I can adjust how much it is unzipped and where along the zipper the opening is (underarm or along my chest)

I am going to do it. Just need some time and to get the zippers. Thanks for talking about why you like two sliders, I would have just gone with one. Makes sense to have more venting options. That link is perfect, sew it in before you cut.
