Glow-In-The-Dark Jacket - perhaps not...

Marmot's come out with the Phenomenon EL.

It's got five electroluminescent panels on the arms, shoulders and hood that are visible from nearly a mile away.

Just turn on the switch and light up like a jack-o-lantern.

Supposedly useful for rescuers and helpful for reading maps.

For the average jill or joe, I wouldn't advise wearing this garment with the power on at night.

I am reminded of an evening earlier this year, around 9 p.m. or so, when I was out running in the dark.

I was wearing this passively reflective jacket.

A tricked-out car full of teenagers came roaring down the street in the same direction I was running, then did a U-turn and came back up toward me.

I didn't like the looks of things but I was on the sidewalk, running next to a concrete wall: nowhere to run, nowhere to hide.

As the car passed me I felt a powerful impact against my gut, and the car flew on with the kids inside screaming bad words and laughing really hard.

I had no idea what I'd been hit by, it was really dark.

Maybe I'd been shot: who knew?

There was liquid running down my body and legs.

When I came to a gas station a mile or so down the street, I saw that they'd scored a bulls-eye with a raw egg right in the middle of my abdomen.

I have to admit, I was pretty impressed at the thrower's accuracy, enraged as I was.

This is how nonviolent people end up in prison, I realized: if I'd had a gun and superpowers, I'd have followed the car and shot out its tires.

I finished my regular five-mile route with the egg coagulating on my skin.

After I showered, I was interested to see that there was a perfect red outline of the egg on my belly.

It lasted for about 3-4 days.

That was the last time I wore my reflective jacket for night running.

And that's why I'd advise against using this tricked-out parka from Marmot if night running or constitutionals are what you're seeking a jacket for.

However, since you insist:

Gore-Tex hard shell, runs on 4 AAA batteries which provide up to 12 hours of continuous illumination or twice that when flashing.

The entire electrical system weighs about six ounces and has sewn-in wiring that disappears between the jacket's layers.

Flexible and shockproof; comes in yellow, red or blue.

$749 here.

Might be just the ticket for sledding with your new Hammerhead.
