It's comfortable, quick drying, antibacterial, and generally awesome. However, the one downside is it is synthetic so in a fire you could end up with serious problems. For this reason I usually wear cotton on the plane and ExOfficio everywhere else.

Why? In the event of catastrophic failure, inhalation injury is a far greater risk than actual burn injury. If the fire is sufficiently severe that groin burns are a possibility, the underwear won't save you.

By the rule of nines, the anterior and posterior torso constitutes about 36% of surface area. The legs are another 36%. The groin itself is only 1%; the total area covered by underwear is likely less than 4% Non-synthetic pants & T-shirt is of greater yield than underwear.


[addendum] Oops, I looked at a picture of the ExOfficio underwear. Coverage is from the umbilicus to just above the knee which IS a significant surface area, about 15-20%.
