That doesn't surprise me on the Kuiu's.
I've about tried it all in the upland pants thing. I don't like any of the Upland pants as they are not waterproof, game breaker for me. I hate being wet. Upland pants are useless to me for this reason. They also tend to be heavy, they are really heavy when wet and take forever to dry. I use two different systems.
Kuhl Silencr pants. Gaiters for grasslands and warmer hunts. Filson Double Tin for later season and heavy cover. The Filson's are hot, and my thermostat runs high. That said for protection from heavy cover and shedding water,nothing is better. Sweathing a little is a fair trade for me. Another reason I like the Silencr, very light weight, not as hot in warmer temps with the chaps. In the heart of winter if there is a lot of snow I wear the gaiters under the Filson's. Great set up.
I had a pair of Kuiu gaiters for years that I used in the mountains. I replaced them with a like new pair this summer. Bought off here in classifieds. They had never been outside. They are trashed and need to be replaced at the end of the season. The fronts of them look like the picture above. Both strap holders on the sides have torn off. Great in the mountians, do not hold up to bird hunting..
Not sure what I will replace them with. Either Stone Glacier, (first genteration on these were garbage) has me a little gun shy. I don't like paying $120 for something to be a beta tester. Like the looks of the First Lite, they appear tough and well made. Crispi also look tough but not convinced they will stay down.
