Since the new challenge is a sandbag mile I thought it would be good to talk what types of sandbags are out there and which ones people have used. Ironmind has a sandbag kit. K2 Fitness has one too. I don't know if anybody has either of these and could talk about it. There is always the classic navy seabag too. Also here are some of the old threads I found about building a sand bag:

Ross Enamait ("Warrior Fitness") has some ideas on making sandbags, here (PDF):

Is something like this "Army-Navy" top-loading duffel bag what people typically use or have in mind for a sandbag? Pretty cheap ($15):

http://www.american-armynavy.com/DuffleTopLoad.htm

There's also a "sea bag" which looks better, made of the same material but without the strap(s) for $20 (about $26 with shipping):

Do you think this would be durable for a 50 to 100 or even to 150 lb. sand bag?

Thanks,
Rene'

OK, another post on this. Sorry to clutter the thread. I feel rather silly posting this, but I thought maybe others were looking to make a sandbag, too, so here goes:

So, what size and type bag to get for this crazy Rutman Mile? My bodyweight is around 150 lbs. I assume I only want a top-loading bag, so I don't have to worry about a zipper failing. (Maybe this is wrong.)

The K2Fitness site has a specifically made bag (which has a zipper):

http://www.k2fitness.net/sandbags.htm
Don't be fooled by other "sandbags" which are stuffed to the brim, stiff and unyielding. For full functional strength benefits, the contents of a sandbag should be loose and non-conforming.

Our BodyBag sandbags measure 27"Lx11"W (not including gripping tabs) and are rounded construction. The weight, when filled can vary, depending upon what filler material you use, and how full you fill them. We recommend filling them with "pea gravel," which when completely filled has the bag at around 115-125 lbs. If utilizing sand, the bag weight can be increased to about 140 pounds when full.
$48.95 plus $6.95 S/H


Unfortunately, they don't give the weight of the canvas used, but I assume it's 22oz., which is what is used on the standard military duffle.

Now, that standard duffle is a 21” x 36” bag (top-loading, 22oz canvas, also available in Cordura nylon, which is probably slippery with sweaty hands). That size bag is roughly double the size of the “BodyBag” above, so seems much bigger than what I want. The standard Navy sea bag is even bigger, at 26” x 36”.

Are there smaller bags? One is a Cordura top-loading duffle that is described as 36" x 11.5" x 11.5" , here:
http://www.perrets.com/st_prod.html?...=508&p_catid=4

but I didn't see this in cotton canvas (though it may be there somewhere).

Here's one that's 18” x 36” made of “Heavy duty, water repellent duck” (those crazy Canadians—quack, eh? But at least they all have health care!). (Min. order of Can$24 required.):
http://www.fcsurplus.ca/shopping/shopexd.asp?id=823

This next one is a canvas bag that is 12” x 36”. Cheap enough at $15 + $4 shipping; however, it is only 12 oz cotton canvas:
http://www.dickssportinggoods.com/sm-champion-sports-canvas-duffle-bag--pi-12543 63.html

Here's another Duffle Bag Medium Size. (12" x 12" x 25") (the other way of measuring is the width of it laid out flat—not sure what this would be). Unfortunately, the site doesn't say what it's made out of, but given that it's an “Army” bag, it should be 22oz canvas (and it looks top-loading):
http://www.bagstogo.com/ (scroll down to “#AD25”)

Finally, this one is a great size, 13" x 28", but have fun carrying waterproof, PVC-coated nylon!
http://www.outinstyle.com/page/ois/PROD/PacksBagsDuffels/pack2622/SESSION_ID/51d 4493ed1287e786df811d2d654c613

Anyway, lots of bags out there. It seems like that 12 oz cotton one is a good size, close to the K2Fitness one if you tie off the end. But does anyone know if 12oz canvas is strong enough for a sandbag? If anyone finds the “perfect bag” for this (cheap, too!), please post a link. Thanks!

Have fun,
Rene'

Wow Rene you went all out in search of the "perfect bag". Hopefully somebody out there can ring in on some bags they have used.

Hmm, now this I like.

I'm not sure how loose and free-flowing it is (which seems to be of benefit) but for rock bottom pricing I think I'll simply try a bag of cement sand with some emptied out and tied up put inside the backpack I used to travel around Europe, which was quite comfy. It's still probably a bit of hassle to have a huge sack of sand around the place, though and the new flatmates probably wouldn't dig it. (See what I did there?)

Of course as you can't use the straps I suppose I could just lug the sack of sand about.

Just a suggestion. Get a cheap canvas "sea bag", top loading. Get sand from a Home Depot, type store. Put two large green trash bags in the sea bag (to stop any sand from spilling, if a bag breaks). Get large zip lock bags, duct tape, a scale, and a scoop. Scoop 10lbs of sand into a zip lock bag. Seal the bag and duct tape it shut (you could double bag for strength). For me (at 200 lbs) I will have 20 / 10lb bags. Now it's easy for me to add or subtract weight by putting bags in or taking them out. The bags still shift, but you don't have to worry about spills. To really get small incriments, you could add a 5 or 2.5 weight plate into the bag. Not a bad idea to duct tape the inside seams of the sea bag.

Bryant,

I am not sure how much weight you want to use, but I have a traditional Navy Sea Bag, loaded less than half full and it is between 180-200lbs. I used 4 - 50lbs sandbags, and it is very heavy. I couldn't imagine walking or running a mile, mostly because of the difficulty of holding onto the bag. I used two layers of heavy duty garbage bags, filled them with sand and folded them over. Next I removed the shoulder straps with a seam ripper and then folded the bag over and completely sealed it with duck tape. I ended up with a large oblong "medicine ball." I think that I might have made it to dense because it doesn't really conform to your shoulder if you shoulder it.

Good Luck,
Ryan.

Thanks everybody for the help.I only need a 165# bag so I think am going to go with the K2 bag filled with sand and a couple 10# plates and I could post about it when I get it in the mail if any body wants.
