Which One Is Better?
It is a matter of expectations and requirements. Both fabrics come with similar qualities, but Gore-Tex clearly has the upper hand in terms of both breathability and weather-resistance.
In long-term wear, it also fares quite well as the material is very durable. However, it requires regular maintenance in order to upkeep the breathability and quality of performance.
This is not an issue with OutDry Extreme, as it comes as a fully waterproof fabric and will remain so for as long you’ll use it. It is much more environmentally friendly, too, so it would be the better option in that regard.
Price-wise, neither falls under the “affordable” category as they range upwards of $200, with Gore-Tex being the more expensive of the two.
