I bought these boots with the intention of going up to Yosemite in March. I wasn't afraid of snow as much as mud and rain. I found the boots to be incredibly warm and waterproof (turns out there was snow on the ground!) For the price I was pleasantly surprised with this brand and their quality, so happy, in fact, that I found my husband a pair by Kamik on Amazon and bought him some too! Thank god for Prime shipping!
