HAI,
This Forum is really helpful; one other way to greatly reduce armpit sweating is through wearing some effective undershirts. For me I was once a great bad sweater but when I used the Thompson tee undershirt I feel so fresh and cool. This shirt is just perfectly amazing. I wore it all day while at work a lot of walking and some bending down and the shirt stayed put. I also love how the shirt feels I am a sweaty person normally and this shirt kind gave a cool feel to me all day. Hope this would help. Thanks.
