Apparently there are a few wind shirt/rain jacket products out now that have laser create small holes in the armpits. I was wondering if these possibly could be replicated with some other technique? I don’t think i would do it in the armpit but maybe in the napoleon pocket and could always just open that up fro it to breathe. Thank you.Mar 31, 2021 at 12:11 pm #3707129Mike BBPL Member
Depending on the size of the holes you could use a hot needleMar 31, 2021 at 12:25 pm #3707133Brett PeughBPL Member
Thanks Mike. Do you think that it would cauterize the edges of the hole?Mar 31, 2021 at 12:32 pm #3707134Kevin BabioneBPL Member
As someone who generates a lot of heat while hiking, I can’t imagine that even 100 holes in each armpit would do much to improve my ventilation. Jackets for me must have pit zips – the bigger the better. I go back to my first Marmot Precip 20 years ago and the pit zips it had. My Packa has huge pit zips too.
Does anyone have experience with a jacket with the holes Brett talks about?Apr 1, 2021 at 3:18 pm #3707297Mike BBPL Member
I have never used one.
Brett if the needle was hot it would melt the synthetic fibers.
I tend to agree with Kevin though and it would take a lot of holes to make any difference. Even with pit zips which are 100x or more ventilation I am clamy and hot when hiking in a rain jacket. My windshirt breathes pretty well, it is an old Patagonia model prior to the Houdini, and I am not sure a few hundred holes in the pits would be of benefit for it.
Also with pit zips you can close them in a down pour, seems like a marketing thing more then a performance thing to me.

You could sew some durable netting into the armpits; but only for a windshirt. I have a Montane windshirt that does this underneath the upper chest area rather than under the armpits, but it also has a loose, breathable DWR fabric cover over the netting.. When making openings in tent walls or garments, netting is sewn in to retain the shape of the item, especially for tent vents. Sierra Designs netting is used because it is much more durable than super light insect netting, and the weight penalty from a small gusset of netting is minor..
But for a rain jacket, as Mike B said, you need a zip closure over the pitzips for downpours if you want to stay dry, especially in blowing storms. The netting could also be retained under the zip closure to keep out flying insects, and possibly crawling ticks, although the ticks seem to be able to crawl anywhere once they get under clothing.
But I think enough needle size holes to provide good venting would weaken the garment. Even a windshirt can receive a lot of wear and tear, and moreso for a rain jacket.
On the other hand, if you can afford to replace gear often, stab away with a hot needle to limit unraveling. But Roger Caffin has suggested a better solution with a poncho that is short and tailored to fit well enough to resist heavy flapping. He has posted threads about it, and many posters have agreed that it is the best solution for those who perspire considerably. There have also been comments about Paramo garments: but since I’ve got a low metabolism, Pagatonia WPB garments, like the light M10, work fine for me in storms. I did have a “Ventile” tightly woven garment, but it was no better at keeping me dry, both from within and without; worse actually than something like Roger’s poncho.
