my hydro pack weighs a ton

[AGENTGRAPE]

has anyone ever weighed their hydration pack with a full bladder ---of water you jokers--- and normal stuff. i threw mine on a scale yesterday it was 12.5 lbs. i have an old camelback bandido butt pack with a 64oz bladder. i was a little shocked, i had no idea i was lugging around this much baggage. how much do your fully loaded packs weigh and what kind do you have? i was thinking of getting a bigger backback style but now i dont know.

[turch]

It's mostly water weight (unless you carry a full inventory of spares like others on the forum have mentioned). Ever come back with a half a bag of water? Gotta play the balancing act and predict just how much aqua that you need. That should solve the issue.

64 0Z of water only weighs 4.3 pounds ( 8.6 pounds to the Gallon). so what else are you carring in that ?

[AGENTGRAPE]

i know about the water weight i usually only fill it 1/2 ice and water about 3/4 full bladder. i carry lots of tools and a spare slime tube, first aid kit, clo2s and some food. i was just wondering how big a difference in weight a bigger pack would be? i think the actual weight with the full bladder for comparasion is what makes more sense since most newer packs come with much larger capacity bladders. so would a mule or hog weigh 15-18 lbs? that is what my question is

I don't even want to know how much my pack weighs, I carry way too much stuff! If your thinking of a new pack check out the Deuter's at http://www.sierratradingpost.com They have an internal frame which keeps them from flopping around and banging your head when your getting radical, 100% cooler in the summer time, because air flows between pack and back. I highly recommend this pack for heavy loads. I own two!

My Camelback Blowfish weighs in at 3lbs. That includes the following...Hoodie and gloves in the pack. In the small compartment I have the following...Med kit, pump, knife, patch kit, compass, mini maglight, mini tool kit and pliers.
It holds a 3 liter bladder but I usually only fill it with one liter.

Since this is a weight weeny discussion...

At it's max density (32 degree F) water weighs 57 pounds per cubic foot.... so 1/2 gallon of water (64 oz) weighs 3.8 pounds.

i guess i need to loss a lot more hydropaks than i thought. no wonder i can't get over those logs. time for a diet.

[AGENTGRAPE]

its not a weight weenie issue!!! i ride a 37lb bullitt as my everyday bike. i just dont like the feeling of a heavy backpack on my shoulders when im riding. the deuters pack looks cool i will check out their site. the butt backs sit low around the hips, and keep the heat off in summer.

While we're picking nits, water weighs 62.4 lbs/c.f.

OK, Question for both of you ( since 32 Degrees was used ) are those for Liquid or solid form ? ( I won't even bring up Gasous )

and since we are picking Nits ! Water at 32 degrees is more dense as a liquid at 32 than as a solid at 32. And I'm too lazy to look up the numbers , but 62.4 sounds right for liquid Water.

Agent i bet you werent expecting answers like this huh? LOL I have a Camelback Mule. I carry a multi-tool a spare tube ,tire levers, patch kit, a cliff bar , my wallet , my keys, a CO2 filler and 2 CO2 cans, i only fill the 100 oz bladder alittle of half full . And ive never weighed it .

I dont weigh my hydro pack. I do remember at some point in my education learning that water is at its most dence around 35f and gets less dence as it heats or cools from that temperature. I wasnt positive so i did a web search and all the information i found confirms my recolection.

The density of water depends on its temperature. Water’s maximum density of 1.0000 g/cm3 is at 3.98° C. The density falls as it approaches freezing.

At 0° C, liquid water has a density of 0.9998 g/cm3.
At 0° C, ice has a density of 0.9190 g/cm3.

Water’s density will start to fall at temperatures higher than 3.98° C, at 50° C, the density has fallen to 0.9880 g/cm3.

pressure also effects water density so the higher you climb the lighter your pack should feel. Have fun!!!!

[AGENTGRAPE]

since water at its most dense occurs when it would be a solid block of ice.it seems like it wouldnt apply, or is this a new he man training exercise.

It didn't make sense to me either... I was using Load & Resistance Factor Design, First Edition (which usually has the answers all of life's questions.) The columns were a little off so I actually listed the weight of "Oils, mineral, lubricants" ....very sorry.

To correct myself:
64oz of water at 32 deg F weighs 4.17 lbs
64oz of water that is boiling weighs 4.00 lbs

So my point would be... fill your camelback with hot water.

Get the damn pony keg out of the cargo hold and you should be fine!! I'm a full member!!! WOO HOO!!

Seriously, I have 2 camelbaks. If I am doing a quick ride, couple hours, I used the lobo. That way I am not forced to carry much. If I plan on doing a longer ride, I bring the cloudwalker. I also tend to try and ride the lighter bike when I lug that thing.

I also have 2 hydration packs. I have a relatively small Platypus that I use for shorter rides that I can hold 2 tubes, an Alien, a few links of an old chain, a Cliff Bar, toilet paper, and 60 oz of water. I also have a H.A.W.G. CamelBack for the big rides. I can add rain gear, lunch, a fleece jacket, a spare bike, and the kitchen sink. (I probably would have been fine picking up the MULE but it's nice being able to carry what you want.)

The Platypus isn't very heavy but the HAWG can be cumbersome.

If you don't like the added weight on you try to figure out a way to add water bottle holders to the bike and ditch the pack altogether. My Fischer came with a mount on the seat post - there's one idea.

This thread is comforting to me..in some sick way.

I pick up my heavy pack, and think I'm a dam fool.
I now realize, I'm in good company.

[Mt.A TODD]

I bet all you "weight weenies" have to take a good bowel movement before you ride. ;D

[C.P.]

I bet all you "weight weenies" have to take a good bowel movement before you ride. ;D
HAAAAAAAAHAHAHAHAHA O.T.F.L.O.L. !!!

[SloMoJo]

HaHa
And pee too, since we all know the density of water now.

OK...now we're getting gross.

[AGENTGRAPE]

thats it! im not taking a pack out anymore just a hydrogen oxygen generator. i wonder if it will fit in the waterbottle mounts.

[splat]

I bet all you "weight weenies" have to take a good bowel movement before you ride. ;D

There is nothing like taking a good dump before you ride! 8) Besides , I hate taking one in the woods! :-\

You guys can take all the bowel movements, dumps or whatever else you want. I prefer to leave mine.

Agentgrape, remember that density doesn't have anything to do with solid . liquid or gas. Wood is solid but usually less dense then water, thats why it floats. Simmillarallilly, solid water also is less dense then liquid, thats why it floats.

The only purpose for knowing any of this that i can use is to determine how far i can fall on to my back from a botched wheely drop and still rely on the waterbag deceleration device strapped to my back not bursting.

Like you did in y driveway christmas eve , off the teeter tooter ?

[AGENTGRAPE]

i understand all that, i just want to know how much a fully loaded pack weighs. i dont need a lesson i mechanical engineering,a simple bathroom scale can provide all the answers. but should i take single or 2ply toilet paper and try to save some weight? lol

[Dawgee]

Agent use leaves that way you done need to carry the paper LOL
