Notes From 48 Hours in the Field (part 1)

Without meaning to, this weekend I got to spend 48 hours in the field. A buddy and I planned a weighted ruck and gear test in the mountains, and we came home gloriously delirious and trashed, and just as I planned to slip into a hot bath, I got an opportunity to join a major search operation elsewhere in the mountains. So instead of a lavender-scented bath, I got a hasty resupply and a 3:00am departure. It was awesome!

Did it really count as being “in the field” for 48 hours, given that I made it home between the hike and the search? Not precisely, but my inner lawyer argues thus: “Yes, your honor, I did get one hot meal. But it was week-old ravioli re-heated in a microwave and eating standing up at 2am. And granted, I did sleep in a bed with sheets. But it was only for 2.5 hours and I was wearing dirty BDUs. And if the court will allow me to approach the ladies and gentlemen of the jury, they will find in my favor just based on how I smell.”

It was paradise, or some near-synonym that means “something gloriously horrible that you would like to do again soon.” And I learned tons, which I will dump out into print here:

1) Options for dressing for high heat

How should you dress for prolonged exercise in high heat? One school of thought says you should wear shorts and a tank top, like a marathoner, and be cooled by sweat and breezes. The other school says to protect yourself from radiant heat by covering up, like a farmer. Both philosophies make intelligent points and science has tried to adjudicate between the two philosophies. But the results are inconclusive.

So my hiking buddy and I ran an unscientific test of our own. We were the perfect pair of subjects: I like to hike in short shorts (though normally I wear long sleeves on top) and he is farmer and works every day covered up in hot sun. So I wore French surplus, which is the ideal type of the “sweat and breeze” approach, and he wore inexpensive technical pants and shirt, ably representing the “block the rays” approach.

On this particular hike, I was the lucky one. We walked in shade for much of the way, sparing me from a lot of radiant heat. And we were carrying moderately heavy weight (45 lbs./20kg for each) with significant climb, generating lots of body heat. We both agreed that I got the better bargain that day. Even with all of our huffing puffing, my body heat dissipated right away, his did not. And despite my exposed skin, I had the luxury of intermittent, partial shade; I did not have to provide all my own shade with my clothing.

Though I lucked out that day, I could also have lost under some circumstances. It is hard to be certain of the conditions you will find in an unfamiliar environment, and as Goggins says of environmental stress, “…more than any other variable [it] can break a motherfucker down fast.” From what I’ve experienced, people can compensate for heat and cold for a long time, but once we cross some threshold, we collapse suddenly and badly. Once that happens, we are so compromised that it’s extremely difficult to save the situation by our own actions.

So on training hikes like this, I might as well carry more gear. After all, once I’ve decided to haul 45# for the hell of it, there’s no reason I shouldn’t trade some of the steel plates or bricks for clothes, shelter-building supplies, batteries, tools, and three days of food instead. So my next experiment in romping will be to devise an easy on/easy off weight so that I can do my weighted rucks with my regular, homely, lovable, eminently useful SAR pack.

2) Map is not territory: On the search, I got lucky and was placed with one of our teams “tribal elders,” so to speak, who has half a lifetime of lessons to teach about searching. She pointed out how wrong the topographic lines on our maps were. The maps were composed from aerial photographs of the tree tops, she explained, and the cartographers’ (highly) educated guesses about the ground below. But they might have had no way to know about some deep, narrow fold in the earth that we were struggling across where the map showed no obstacle.

3) The compass is king: All of our search teachers emphasized map and compass skills, and early on they told us that the compass isn’t just an analog backup in case your GPS breaks. But only now have I come to understand why. First, my GPS is great at telling my location and my track, but it sucks at telling my direction. But more importantly, if I’m staring at my GPS unit, I’m not searching, I’m just walking. With a compass, I can set a heading, find a landmark to walk toward, and then keep my eyes up and moving. (Uncle Ron, one of our nav gurus, even teaches a clever, quick trick for laying your compass on top of your GPS screen and getting map bearings to a distant objective. Then you can put your GPS away, glance down at your compass only occasionally, and still arrive at your destination.)

The Unglamorous Favorite: La Musette F1/F2

Part II in our series on “The Je Ne Sais Quoi of French Surplus”

Can you call something your “favorite” if you find it uninteresting and humdrum but you still choose it over most other things? If so, meet my favorite daypack, the French “musette F1/F2.”

This particular F1 has endured 40 years of people doing stupid things to it, like loading it with 50 lbs. (23kg) of bricks, and it’s still as strong as the day it was made.

I guess I love this thing. It’s basic and boring, but based on my actual behavior, it must be my favorite, because I use it literally every day and take it into the field several times a month.

My SAR pack, a tricked out F2

In about the Seventies, the French army replaced their simple canvas modèle 50, which they’d carried through their Indochina and Algeria campaigns, with the musette F1, made of a clever rubberized fabric to keep water out. In the late Eighties they issued a slightly enlarged version, the F2.

You can find both on the surplus market for a little as $20. Also available but far less common are Austrian rucks that seem clearly like improved homages to the F2.

For a 1970s design, these bomb-proof French packs ride pretty comfortably, sitting nice and high on the back. I can pack almost 40# (18kg) of bricks into an unmodified F1 before it grinds against my low back.

Though the straps can scarcely be adjusted, they have the golden ingredient for comfort: they are broad. Not padded, but broad. (I owe this discovery to Sgt. Šileika, the Lithuanian trail Yoda.)

Broad straps are comfortable. Not padded, but broad.

All I can criticize the straps for is that you cannot adjust them for length. However, we fix that in just a few minutes. We just need to replace the original “quick” attach hook.

This “quick” attach hook is anything but quick. It also leaves no way to adjust the strap length.

See, the pack was designed with the idea that first you’d put your right arm through the strap and then, instead of awkwardly slipping your left through another tight strap, you would just have that left strap flopping free and then re-attach it to the pack with a hook near your left hip. (This may even have been necessary to make it fit with the FAMAS rifle’s unusual sling.)

But that hook is impossibly clumsy and slow (at least for me), and you can’t shorten or lengthen the strap to cinch it up to your body.

Happily, you can change all that for $1. Cut that hook off and replace it with a “G hook” and a short length of 1″ (25mm) webbing. And, regardez! You have an adjustable strap. (Believe me, if I can do this, you can do this.)

Replace it with a little webbing and a G hook. They’re $1 apiece. (You could also use a new spring hook or a spring bolt, but this cheap, faster to use, and adjustable.)

While you’re at it, replace the buckles, which as one commenter writes at La Tranchée Militaire, “… are almost impossible to use because they give you so little room to pass the straps through,” and you have to thread/unthread two long straps through two slots each.

The original buckles are slow and clumsy, but you can replace them.

Instead, buy a pair of 25mm “split-bar” buckles. You can slip them right on and you don’t even have to remove the original buckles.

Finally, take my advice and get six “web dominators,” which are basically little bungee spools for loose straps flapping all over. You’ll want them because this thing has about 2m of extra straps, and unless you’re currently using them all to strap stuff all over the outside of your pack, you’ll want them out of the way.
