What is the longest you have been in kit for?

[Gaius Colletti]

An update, work let us wear costumes in honor of Halloween yesterday, I worked the last half hour of my shift in full kit (LS, helmet, gladius, balteus, soft kit) and then took my daughter trick-o-treating in full kit. I had also worn it for several hours during two costume parties last weekend. Needless to say without having a proper subarmalis still, my shoulders hated me

Still that does not compare to what many of you have said...
