Well, I'll get right to the point. All of the men in my dad's family (myself included) sweat profusely in the slightest heat. I'm young and lean, but my brow beads up the moment I step outside from the A/C. With hunting it's not a problem because the temperatures are usually pretty comfortable in April and certainly so later on in the fall and winter. But I'm having a real problem keeping sweat off of/away from my holster now that Summer's here.

My preferred carry method is strong-side inside the pants, with a lightweight button-front shirt concealing the holster. Can anyone recommend a good inside-the-pant holster than protects from moisture?

I should also mention that I'm currently packing a Steyr M40, which is about the same size as a SIG P228/229. I'm also on the lookout for a good sweat-resistant holster for a Ruger SP-101 (for my wife, but we might switch from time to time).
