I just got the REI trail running gaiters for warm dry weather at Aron's recommendation and they look like they are going to be good for warmer and not so wet weather. Thanks Aron, I have been needing something like these for quite some time. Here in WA and Northern ID it can get really wet from late August on in the mountains, so that all of the thick foliage is constantly wet weather it is raining all of the time or not. I have the Kennetreks, and also the OR Croc gaiters like Becca has on. I find the OR Crocs just a little more waterproof and tougher than the Kennetreks with constant brush and water exposure for big game and upland hunting. Infact, I am amazed by the OR Crocs as I am very hard on gear. I don't find them to be noisy, and when it is really wet and windy I end up fastening the upper portion to my bare leg above my socks and inside my pant leg anyway for a complete waterproof barrier.
The only 10 day hunt I ever got a chance to go on where we were packed in by horses too far for me to want to hike back to the trailhead, I forgot my OR gaitors as it was 85 degrees and dry in the low country when we took off. It rained the entire rest of the time and my feet were wet the rest of the time from water wicking down my socks into my boots. My feet were permanently wrinkled and were cold if I stopped hiking, and my boots were twice as heavy as they normally would be. Inbetween bivy hunts, I tried to dry them by a campfire, but the silicone waterproofing spray I had so liberally applied to the boots before the trip, kept wanting to ignite on my boots if any spark from the fire came near them.
The gaitors are my most important piece of my rain gear I think if I am wearing regular hiking boots and no rain pants which is usually the case (I can put a contractor bag from my survival kit over the rest of my body if I had to).
