I have a great explanation why I NEVER use gators for my style of hunting in the Northern US. I hunt relatively open country and spend about 75% of my time on the ground glassing and 25% hiking. There is no way I can stand and glass through binos and a spotter for hours and hours. I sit down, relax, and are way more stable.....especially when the wind is howling.
If it's wet enough to need gators my rear end and legs above gators would be soaked when I sit to glass with just gators on. My legs are 100% covered when I sit or hike if it happens to be raining or snowing. There is no way I'm going to wear gators plus rain pants or carry both around in my pack.
As I also mentioned, if it's going to be wet I grab my light weight, breathable rain pants. It's great insurance against getting totally soaked by a quick storm that may come through. I mostly scout and hunt at 6,000 to 14,000' elevation. At high elevation there would be a great possibility of getting soaked just about every day in the summer by late afternoon storms in elk, deer, sheep, moose, and mtn goat country. If I just have gators I can guarantee I would be totally miserable for hours upon hours glassing when sudden storms come through. I've been on marathon hikes while antelope scouting in the prairie.....same thing gators would have done nothing when I was hiking miles from my truck and the sudden rainstorms blew through. I hate being wet and so I go prepared for rain!
I haven't heard anyone that wears gators explain what they do when it's raining, snowing, or glassing on the wet ground to prevent getting wet above their gators? It sounds like most of you must stand and hike all day rather than sit down? Maybe you hike into areas when there is dew on the ground and don't sit down until all the dew is gone? You must also be in areas that don't have afternoon storms? I can possibly understand if you live in a super dry area, with 0 wet brush, no afternoon rainstorms, no snow, etc not needing rain pants?
