I actually bought this for my 11 year old son to climb Mt St Helens. These were the smallest gaiters I could find. They did the job well however the fit at the top was slightly large for my kids skinny legs. Had to cinch em up tight and the buckle was a little difficult to get a good clamp due to the excessive bunched up material. The solution of course is to make a junior gaiter (hint hint). Thanks for a great product.
