3 lb Pack, 2 lb Sleeping Bag, 3 lb tent
This is, perhaps, your biggest opportunity to reduce backpack weight. Seek out a good 3 lb pack that is relatively comfortable with 35 to 40 pounds in it. Since, most of the time, you will be carrying less than that, the suspension of that 3 lb pack should be adequate for you. Get a good 2 lb, 20 degree, goose-down (or comparable synthetic) sleeping bag and a good 3 lb 3 or 4-season tent. Let's see, 7 lbs minus 3 lbs (pack), 3.5 lbs minus 2 lbs (bag), 5 lbs minus 3 lbs (tent)--that's a weight reduction of 7.5 pounds. SEVEN AND A HALF POUNDS !!! Or better yet elimanate all this weight and get a ENO Hammock at 1 lb. 4 oz.
Eliminate Map Edges
Cut em off ! I know, I know. This is some kind of neurosis, isn't it. Actually, it's attitude. If it doesn't have AT LEAST ONE FUNCTION, I don't want it in my pack. I cut off map edges (leaving just enough room for bearing calculations, notes, longitude & latitude markings, and other important map attributes.)
About Stuff Sacks
I carry much of my gear in color-coded stuff sacs and zip-loc freezer baggies. Where I use stuff sacs, I adhere to the following. (1) Use the right size sack--wasted space means unnecessary weight. (2) Cut off labels inside sack (3) Allow just enough drawcord so sack can have full opening--cut off the rest and melt the ends so they won't unravel (4) Use the strongest-smallest plastic cord-locks you can find. All this may seem insignificant, but it adds up after a while.
Mete-Out Appropriate Portions !
Sunscreen, bug-juice, toothpowder/paste, condiments, prescription medicine, antacid, vitamin I (ibuprofen), toilet paper, and anything else for which you can measure usage according to time (weeks, days, hours). Mete out portions of these items that will be appropriate for the time you'll be in the backcountry. For some items, estimate conservatively so that you'll have a little extra if conditions turn out to be differently from what you anticipated -- (for example, worse bugs, more sun, bigger headache, etc.). I use little plastic vials that are similar to film canisters but smaller -- but have same tight-fitting lids.
NOTE: I don't use film canisters because of the chemicals used on film & possible residual in the canisters.
Cut off unnecessary labels and lengths of cord. If garments have cord locks, replace them with lighter versions, or instead, use small doubled-up patches of light-weight leather with slits. I've noticed that some manufacturers have been doing this, also.
If you carry extra clothes for emergencies, cut off pockets, cords, tags, unneeded linings, etc.
I have saved some weight on hats by cutting out labels and replacing plastic adjusting straps with elastic. It feels better and won't break in the field as easily as the plastic ones.
Shorten nylon webbing straps wherever possible. I once saved a quarter pound (4 oz) by removing the hypalon crampon patch from the top of my pack's lid and the nylon belt loop with foam backing from the inside (which allows the lid to double as a hip sack when removed from the pack). In addition, I removed a couple of plastic loop fasteners on the sides of the lid used as part of the hip sack configuration. Most of the time, I don't need those parts (and their corresponding 1/4 pound !).
For the times I was taking a long trip which included some day-hiking or I needed the heavy-duty hypalon patch, I purchased a second lid.
Remove Manufacturer's Labels
I couldn't believe it. I just bought this ultra, ultralight, high-tech tent and here's this big (5 1/2" x 3 3/4") label on the outside of the door advertising the tent makers name. The label's weight was added to by the waterproof tape applied to its opposite side, on the inside of the tent. Needless to say, I removed the label and the waterproof tape, then sealed the needle holes with a light bead of SeamGrip. That label, itself, was not waterproof and, in fact, soaked up water like a sponge. In the field, that label would have added two to three ounces of weight to my pack (depending on whether it was dry or wet).
Remove labels & apply a light bead of SeamGrip onto the needle holes, wherever possible--tents, packs, bags, clothes, even on boots (where they put those useless metal gore-tex tags).
Boots, Shoes & Laces
Two tips here. The first, definitely do it. The second, consider it a potential way to significantly reduce relative pack weight, but don't take it as gospel. Analyze your own situation, experiment, and do what's safe and healthful.
Firstly, on shoes and boots, I cut off excess shoe lace--for two reasons (1) excess shoelace means unnecessary weight and (2) excess shoelace means safety hazard in the bush. Ever have a big lace-loop catch on an exposed root or tangly bush ? After you cut them, scorch/burn/melt the ends so they won't unravel.
And secondly, as your pack weight goes down, your requirement for heavy boots is reduced, as well. Since each pound on your feet is supposedly equivalent to 5 pounds on your back, you can reduce the relative weight of your pack by getting a pair of lighter weight boots.
If you have, as one lightweight packer terms it, entered the new paradigm where your pack weight is really low--25 pounds for four or five days--you might even want to consider going with a sturdy pair of 2 pound cross-trainers or running shoes. Like I said, though, there's potential here, but experiment. What works for me, may not work for you.
Consider the implication. Assuming the "1 pound on the foot is equal to 5 pounds on the back" theory is true, trading-in the 4 pound boots for a pair of 1 3/4 pound running shoes (with vibram soles) would decrease your relative pack weight approximately 11 1/4 pounds ! It's at least worth a second thought !
Instead of carrying a pillow, stuff your clothes in one of your larger stuff sacs--makes a dandy pillow. Your clothes will be dry & maybe even warm in the morning.
Scouring Pads for dirty Pots & Pans
Use sand, dirt or moss instead of a scouring pad. No soap suds in the water & no dirty pad to mess with.
Alternate tips for pot cleaning (submitted by Rich Hawes, 6/23/04)
Although camp shoes are considered a luxury item for neurotic minimalists, they have multiple uses, most notably, a haven of rest for weary feet. If you carry them -- and I sometimes do -- look for lightweight water shoes, rather than lugging along your much heavier tennies or running shoes. I used to carry a pair of Speedo Surfwalkers which are several ounces lighter than the Nike Aqua Socks.
Another solution, if you want something just for shuffling around camp, get a cheap pair of cloth night slippers from one of the local chain department stores. The slippers are practically weightless, and if you're lucky, they may even last an entire season.
NOTE: If I'm on a venture which includes river crossings or swimming in shallow lakes, I'll still carry my Speedo Surfwalkers.
Batteries are Heavy--use Candle or Oil Lamps Instead
Because batteries are heavy, I use my headlamp only for night travel or answering the midnight call.
Otherwise, for in-tent activity, I use a candle lantern or, more recently, a candle-lantern converted to oil (it's lighter, cleaner, and lasts longer). Both can be purchased at just about any outdoor shop. In addition to providing light for reading and writing while in the tent, they are excellent for starting fires, even if the wood is damp.
Keep in mind, this may not be advantageous to you. It depends on how long you're in the outback and how much light you require after dark. The longer you are out there and the more you require artificial light in your tent, the more advantage and relative weight saving you will realize by using the lantern.
NOTE: A tip I saw in Backpacker Magazine: If you carry an aluminum stove windscreen, use it as a light reflector placed behind your candle. Another example of multiple functionality.
Replace your Alkaline Batteries with Lithium
Replace the AA Alkaline batteries in your flashlights with AA Lithium batteries. Lithium AA batteries weigh 50% less than alkaline and last about 3 times longer. They only cost about $5.00 for two, so you actually come out ahead in the long run. One reader at The Lightweight Backpacker website says he doesn't carry a candle lantern because the lithium batteries are so light and last so long - he just uses his Petzl Micro headlamp for everything.
If you use an insulated mug (hopefully a lightweight one, like the ones sold by REI, LLBean, Campmor, Backpacker Magazine, etc.), do you need to take the lid during the summer ?
Actually, other than during the Winter when a thermal mug is important to keep your hot drink warm, do you need a mug at all ? You can save four or five more ounces by leaving the whole mug at home and using your cooking pot or water bottle for hot drinks.
After using your water filter, pump it to flush out remaining water.
Using Your Gear for Emergencies
Rather than carry triangular bandages, SAM splints, bunches of medical tape and such, consider the following:
You can fashion a sling by using a safety pin (or pins) to (1) attach a shirt sleeve or front shirt-tail to the top of the shirt or (2) attach two legs of a pair of fleece pants or thermal underwear bottoms which have been draped around the victims neck.
Improvise a splint by using (1) a closed-cell foam, self-inflating sit-pad or sleeping-pad (2) backpack aluminum stays or (3) ski and/or hiking poles.
Improvise an emergency litter or stretcher using (1) a sleeping bag with hiking staffs or wooden branches for carrying handles or (2) a closed-cell foam, self-inflating mattress.
Select ultra-lightweight - yet strong - lexan utensils. As with the toothbrush, cut off as much handle as possible and sand down the cut corners. Do you really need anything other than a spoon ?
NOTE: I've looked at the new titanium utensils & the lexan utensils appear to be, at least, equally lightweight and strong, for my purposes.
Carry Less Stove Fuel
Test how much fuel your stove uses to cook your favorite meals & drinks, plan accordingly, and only take the necessary amount of fuel. If you are using white gas, factor in extra for priming purposes. Also, regardless of what kind of fuel you use, factor in a little extra if you are going to higher altitudes where the air is thinner.
Always cook with a lid on your pots. This enables better heat retention, so the water boils faster, which uses less fuel, which reduces the weight on your back !
Also, try to take foods which don't require cooking. Lunches and snacks, especially. This will reduce the amount of stove fuel you will need to carry.
Blacken Your Pots !
Another tip for using less fuel is to blacken your cooking pots. A blackened pot will absorb heat faster than a shiny surfaced one.
Most pots do not come pre-blackened, but over time may become that way, especially if you use them in an open fire. Of all the pots in the "kitchen inventory" section of my "gear closet", my SIGG Inoxal pots are the only ones that actually came with a black outer surface. However, no matter, I always paint my pots with flat-black stove paint, as soon as I get them. I recently did this with my Evernew Titanium pots. The black surface absorbs and distributes heat faster than a shiny surface.
