Hi Andy, I think as long as you go with a full lace unit (French lace or reinforced SFSwiss lace you shouldn't have any problems at all with wearing your full cap in a warm/hot environment. Lace is the most breathable of base materials, and so light you hardly can feel it at all once it's attached properly.

As far as wearing a full cap in business situations, lots of guys do it everyday without any problem. As long as the density of the piece is a good match with your own natural hair and the style and cut is appropriate and complementary to your facial shape, nobody should suspect a thing.

You might want to consider adding a little facial hair, adding some glasses or getting a tan when you start wearing to throw people off the change a little. Most will notice something's different but won't be able to put their finger on exactly what has changed.

Be sure to read all threads by Paul in Ireland for lots of good info on everything from how to properly design a full cap template, getting the unit, cutting it in, along with lots of attachment tips. He always posts amazing photos showing every step of working with a full cap from start to finish. (A picture is sometimes worth a thousand words.)

Good luck with your new full cap!
