Pit-Zip or not Pit-Zip?
« on: June 12, 2010, 07:30:01 PM »
I was thinking of buying a Marmot Gore-Tex jacket and I was debating between the Nano and the Minimalist. The main difference for me is the pit-zip (the zipper under the arm), a friend of mine swear by that feature and I was wondering if you guys think it is worth the $40 difference between the two jackets. Any experience?

Maybe I'm answering a little late and you've made your decision already? But definitely spend the extra $40 and buy the one with the pit zips.
 About 10 yrs ago I bought a nice Banff brand gortex bike jacket (made in Canada) but without pit zips. Soon after I began to notice other rain jackets with the zips; maybe they were pretty important. A few years later, I bought 2 pit zips from a fabric store and asked a friend of my mother's to sew them in. What a huge difference it made! I didn't have to rely on getting air to travel all the way up my sleeve for ventilation, just open up the pit zip and I'd cool off right away.
 The longer the zip the better. I now have another rain jacket (that came with pit zips this time!) and the zips are quite a bit longer than the ones on my old jacket; even better ventilation. The latest version of my new jacket (MEC) have the pit zips go right down to the bottom, they might even detach there too, not sure.
 So go for the one with the pit zips. You'll be glad you did!

No it was not too late and thank you for the great info. I would have never thought about adding pit-zip to a jacket, it's a great idea, I will do it on the cheap jacket that I am using now. I am still debating on which Gore-Tex jacket to buy. I really like all the features of the Gore Bike Wear and I like the paclite goretex but it is a bit pricey for me. So I'm hoping to find a good sale!

Recently my girlfriend and me had some very wet days on the west coast of Scotland. She has a 200 Euro rain jacket with pit zips, it is still new. I have a much cheaper one without zips, 5 years old. After all the rain i was still dry, she got all wet, the zips leaked.

Peter, if your girlfriend's jacket leaked I doubt it was due to the pit-zip alone. I would think it is either due to a poor design or perhaps even a factory defect of the jacket because afterall a pit-zip is a zip just like any other zip on the jacket (front zip, pocket zip etc). I see no reason why a pit zip would leak more than the front zip for example, especially while biking it would be the contrary and any goretex jacket has some kind of zip somewhere. The zip under the arm is no different than any other zips. I used both type of goretex jacket, first without a pit-zip and for the last 5 years I use a gorebikewear with a pit-zip. I would never buy one without one. This is so much better especially while going uphill. It feels so nice to feel that little wind when you start to get hot and sweaty inside of the jacket. Pit-zip actually increases the waterproofness of the jacket because the classic cause for goretex fabrics to leak is the accumulation of H2O on both side of the fabric. So when you are excersizing the goretex starts to leak when you have sweat accumulating on the inside part of the fabric and rain on the outter side. Since pit-zip increases the ventilation inside the jacket, it decreases the amount of perspiration built up inside the jacket therefore it decreases the chance that the jacket leaks. I would suggest you contact the manufacturer and see if they can do something about it, it is not normal that a new $200 goretex jacket leaks.

From the wet patches on the shirt she was wearing underneath her jacket it was clear that the zips leaked.
It is true that the front zip leaked as well. Maybe it is a design problem. I would think that zips are never 100% waterproof, so less zips is better. She has an Odlo jacket, not Goretex, but still I think it should be waterproof for that price.
I never had a jacket with pit-zips and i don't sweat much.
She just told me she likes the zips when it is not raining too much. But what is the point of bringing a rain jacket that is really comfortable only when it doesn't rain much.

A lot of companies claim that their apparel are waterproof when they clearly are not. I am sorry to hear that Peter this is not right for that kind of money. Today there are only 2 fabrics that are waterproof and breathable at the same time: goretex and event. So if if anyone want to spend money on a jacket I would recommend choosing one of these fabrics. I never used event but I heard good thing about it and I recently read an article about an engineer from the US military specialized in technical apparel and he was comparing goretex and event fabrics as equally efficient, but as he said there is no breathable fabric 100% waterproof he added something like: If you need clothing 100% waterproof, wear plastic!
