Chris Cage at Greenbelly meals has a nice review on gaiters.
I use Dirty Girl gaiters on short well tracked routes, but Leva Gaiters are stronger for rougher routes. (reviewed on earlier post).
I prefer Simblissity Leva gaiters from Brett Tucker, but unfortunately he has temporarily stopped production. I do hope he re-starts. I was lucky that he made me a second pair (to keep in storage) before he shut down - Thanks Brett!
Update (19/12/17) I am mostly wearing Dirty Girl Gaiters these days.
Here's the link to Chris's review. https://www.greenbelly.co/pages/hiking-shoe-and-boot-gaiters
Oh, buy the way, his business is high nutritional hiking bars. I have already reviewed these on this blog. But check them out at https://www.greenbelly.co/
They are great! Only issue would be postage cost from USA.
