Just wanted to say I give this the “Field-Tested” approval. I’ve used this daily while rock climbing, backpacking, and doing my demanding outdoor field work in strenuous conditions. I’ve never found a natural product that works as well as this one-and I use such a tiny amount! I was worried it would irritate my skin as other baking soda products did- but it didn’t! I am so relieved I can use a product I feel is safe to use and prevents me from feeling embarrassed about my stinky pits. Thanks!!
