I have carried one for years during fall, winter, and early spring,,even while stationed in Florida.

A Took (is that spelled right???) has proven useful most of the time and "extremely useful" some of the time.

Once, unexpectedly, during winter in northern Florida, I was invited (aka: go along for the ride) to exfiltrate an SF (A) Team from the beach along the northern Florida coast, with 4-5 ft breakers.

I had my M-5 Field Jacket (with bandanna, gloves, and a Took) and a wet suit. I carried my EDC and a signalling kit. We got the Team, busted our way past the breakers, and found the "Darkened Ship" with a compass.

Another truly great unexpected adventure.
