Washing Gore tex and other water proof fabirics in any kind of detergent is BAD. The reason you loose you water proofing through out the season are because the water proof pores get clogged with dirt and oil etc. The same thing happens when you wash them with any normal detergent. You want to wash them with a non-detergent soap. The company Nikwax, makes a tech wash that is designed to be just that. Nikwax is a life saver! if you live where it's wet. They make a bunch of different water proofing products that work very well. This is my little combo, wash jacket and pants in TechWash, then use the Direct Wash in water proofing, then i Waterproof my gloves with the glove spray. Each product is around 10 bucks USD. You can find them at most ski shops, or REI type stores. Just ask them where the Nikwax is, you will be very happy. This is for anyone that has lost water proofing, or wants added, or just wants to wash ski gear.
