So, when I last went out of the country, it was super duper nice to have my Scottevest with hidden interior pockets. Very relaxing not to have to stress about pickpockets or purse thieves knowing that the essentials were safely tucked *inside* the clothes.

But there doesn't seem to be anything like this for very hot, humid travel! We're going to Buenos Aires in February, and it's supposed to be 80F+ and very humid. Waist belts, cargo jackets/vests, etc. will not cut it. Everything with a security pocket system on sites like Exoffico, Scottevest, etc. seem to be made for travel in rainy, cold weather - or simply with wrinkle prevention in mind, without any security features.

I would have loved to find something similar to activewear bras or tanks with zippered key compartments, except with the compartments large enough to hold a passport... I have come up with exactly zilch.

Do any of you have solutions for securing travel docs when it's too dang hot to wear much clothing?
