First Gear List, Help

I can't access your list. If you've got no response, maybe that's why.
Or I'm doing it wrong. Maybe check your link. Good luck- just trying to help.

The URL to the list seems fine.

… perhaps a copy & paste error?

Here is an embedded link to it

That's a mighty fine list! My biggest suggestion is that you add a backup firestarter—a firesteel or perhaps a mini bic. There's a long-running thread about backup firestarters over on the SUL forum, and even among SULers most people carry at least two, normally three, ways to get a flame going. Especially in the cold, wet weather you'll encounter in your area, that .9 ounces (.4 oz for a mini BIc, .5 oz for a firesteel) could save your life.

You might also consider replacing your short sleeve baselayer with a long sleeve one. Sleeves can always be rolled up, and I found that my l/s shirt with the sleeves up and chest zip down is cooler than a regular t-shirt. You might need the extra insulation because if it's getting down to 15º, you're pushing the limits of that Hadron.

Your lower extremities would probably enjoy having some rain gear. A good cold rain is no fun when soaked into your pants.

If it's as low as 15 outside I would bring more then a cut Z-lite. Of course site selection can diminish the need for more, but some places up north have designated sites which are no good for natural ground insulation.

In regards to the AT, depending on the time of year I sometimes don't worry about a backup firestarter. That isn't advice of course, just how I go about things.
