MYOG Camera Case Doubles as a Shoulder Pouch

Here's a simple design I thought of recently while I was out hiking with my son.



My goal was to make an UltraLight Camera Case that would double as a shoulder pouch. This will keep the camera protected from the elements and within easy reach at all times so I don't miss any photo ops.



The material I chose is a super tough 1.43oz (per square yard) cuben fiber that I purchased from ZPacks. I'm a bit addicted to this stuff right now because it's so durable and lightweight. It's the same material I used to make my backpack about 15 months ago, and it has held up beautifully. I angled the top enclosure, making the front lower when attached to the shoulder strap. This makes it easier to get your camera in and out without fuss, and also helps to shape the front when it's open. The taller back is necessary to form a rain proof closure...



I used 1.25mm shock cord instead of a normal drawcord, with no cord lock. This makes it easy to open and close with one hand while hiking. To close, simply pull the shock cord over the front and around the back of the camera, which folds the top opening down making the case rainproof. I sealed the seams with clear silicone to ensure it's water tight.



When not in shoulder pouch mode, it works just as well as a stand alone case. I'll store it like this on my tent floor at night.



I've been trying to think of the right design for quite a while, and I think I've got it pretty close. Oh yeah, I almost forgot...it weighs only 0.10oz!

2 Hikers, 14 days, 70,764 calories

My son and I are about to head out on our thru-hike of the John Muir Trail, and our resupply boxes are almost ready to go. Rather than carrying 14 days of food with us, we will be mailing supplies to ourselves along the way.

It seems that backpacking sites tend to focus mostly on gear and trips (this one included). I don't think we see enough information on the very important topic of trail nutrition. You can make all the right gear choices to get your base weight down to "ultralight" status, then blow all the weight savings by carrying the wrong kinds of food. Pictured below is 14 days of backpacking food (7 days x 2 people).



My goals for our meal plan are...
#1 Well balanced nutrition, high energy for 10+ hours of walking per day.
#2 Simple meal preparation on the trail.
#3 Go as light as possible without going hungry.
#4 Use as little stove fuel as possible.

One special consideration for this trip is that our food has to fit inside a bear canister, as they are required in the area where we will be hiking. Of course I don't want to carry some gigantic (i.e. heavy) vessel to carry my food, so I leaned towards smaller, calorie dense types of foods such as couscous in lieu of pasta. Here is our menu...

Breakfast consists of nuts, berries, dry milk...half prepared with couscous, and for variety the other half with rolled oats. A favorite mid day snack is flour tortillas, pepperoni, and parmigiano reggiano cheese - kind of like a trail pizza!



My idea for dinners was to be able to mix a few ingredients to create several different meals, and have meal preparation take just a few minutes. Pictured below is 14 days of dinner...clockwise from top left, Delight Sauce, spiced olive oil (thanks for the great idea Mike Clelland!), black bean soup with instant white rice, couscous, and instant mashed potatoes (Idahoan Loaded Baked of course, everyone knows they're the best)...yum!



Will it all fit? There's some strategy to this. Bars across the bottom, then some granular food to fill in all the gaps. Note that the bags of food are under-stuffed in order to squeeze into any available spaces. More bars and flour tortillas fit nicely around the outside, and the rest goes in the middle.



It just fits, a weeks worth of food in this BearVault BV450 container, which is rated at 4 days capacity. Their larger size weighs a half pound more, and wouldn't fit inside my backpack.



Some snacks are purposely left out for the day (food only needs to be inside of the bear canister if you are going to be separated from it). I'll have to find room for that bottle of spiced olive oil before the day is done, which shouldn't be a problem after dinner.



Deatils details...yes I like them. My nutritional goals are to have lots of real food - nuts, whole grains, etc. I try to go with a balance of 50% carbohydrates, 35% fat, and 15% protein. The highest calories per ounce are from fat, but you need to try to maintain a decent balance. Don't worry if you don't hit your percentage goals dead on...they are just a target and a good way to see how different food choices affect your overall nutrition plan.
