That is it. The Ultra Light is what most people here use. My Size XL weights 6.5oz for the jacket and 5 oz for the pants. They run pretty big, I am typically XXL in everything I wear. The pants run especially large.
I researched it from old threads and such and it appears the Dura Lite Driducks would be more durable, some people use them but I think they are quite a bit heavier although I never was able to get a weight on them, never found any to look at in person. In the reviews there is a very positive review on the Dura Lite with a guy wearing one on a saltwater coast, he is wearing a blue jacket in the picture, his are Dura Lite but I think the majority of the rest of the reviews are the Ultra Lite. I wish they would separate them out in the reviews section. I read a review on amazon or something where someone said something to the effect of 'I am a light backpacker and bought these Dura Lites, they are not what people buy for light backpacking, these are quite heavy, get the ultra light instead'.
