In terms of keeping you dry, that is. I wore my jacket on a planned rainy day hike. It was fine on the way up when there was only an occasional burst or a bit of drizzle. On the way down, it soaked me through during a torrential down pour - not exposed ledge but through the forest? The jacket is several years old. How long does the waterproffing last?

You need to understand the dynamic of "brethable". There is no such thing as a truely "breathable" rain jacket when you get to the exertion level hikers get to (it is not a total lie since at rest the jacket will let out enough body moisture to remain dry inside.) So what you were soaked by most likely was not rain water, but your own sweat.

To add on to what Brian said, it might also be a factor of clogged pores. If the jacket hasn't been washed and/or treated in a while, the porous ability may be clogged. Washing and treating with the nixwax revived my jacket.

Post subject:  longevity of Gore-Tex

So, how long does a Gore-Tex jacket last? While hiking the "Rainy Day Hike at Pawtuckaway" (50 More Hikes in NH) on Sunday, the perfect day to test old and new clothing, I discovered that my old Gore-Tex jacket failed :( My new Gore-Tex pants and boots were fabulous! Stayed nice and dry. My husband's new EMS version of Gore-Tex waterproof jacket kept him nice and dry, also. But me? Soaking wet hair, shoulders, arms, even the tissues in my outer pocket were soaking wet. Granted, the jacket is several plus years old and had been washed according to the manufacturer's/product's directions several plus times. So, that led me to believe that old Gore-Tex may at some point fail. I understand that the Gore-Tex used in artery by-passes is supposed to last 8-20 years. What has been your experience? This was a torrential rain storm, but oh so beautiful to be in the woods of Pawtuckaway State Park. Also, how do you keep the contents of your day pack dry? Do you wrap each item in plastic or do you have a bag for the entire pack? If so what do you use? Thanks :D

Gore-Tex will break down over time. How long it will take is depends on several variables. How it has been cleaned/how often it has been cleaned, how it has been stored, how much sun exposure it has gotten, if the outer shell has been treated/retreated. Gore=tex is made up of layers (I don't know how many) of very breathable fabric. It has tiny little holes in it that let water vapor out, but small enough not to allow water vapor to come in, or so they claim. What really makes it water proof though is a thin layer of polyurethane on the inside, which takes away most of the "breathable" qualities. This is the layer that will fail. It will break down and allow water to pass through. It was probably a combination of sweat and that polyurethane layer failing that was getting you wet. But basically, if your out in the rain, you're going to get wet, old/new gore-tex or not. Gore-tex will keep you dry, but only to a point.

As for the pack, I have a pack cover, but I've never used it (it came with my pack) because I keep the things I don't want to get wet in ziplock bags. Bigger things like sleeping bags, just use a trash bag, or just use a trash bag as a pack liner.

Here's a follow up to my initial question. From LLBean: no answer re: life expectancy of Gore-Tex, but a reiteration of the 100% satisfaction guarantee policy; from EMS: encouraged using correct products to lengthen performance of garment and an acknowledgement that the product will break down over time, the length of time may depend on the quality of garment - more expensive? lasts longer. Also, an interesting post at www.trailspace.com/forums/gear-selectio ... 62420.html written by a Gore-Tex product user who contacted Gore-Tex Co. with a similiar concern. That's great news, Kathy! And thank you, Andy.

I do this. Those heavy-duty thick plastic shop bags are perfect. You never have to bother with a pack cover in the rain or snow when you line your bag with one of these.

As for the Gore-Tex jacket, yeah... it'll lose it's repellent nature after a while. I was reading in the new Backpacker Mag gear porn edition that they tested a rain jacket that won't wet out. They were 23 washes in at the time of the writing, and it was still repelling as though it were new. It was $350 :shock:
