Ratsack for Grand Canyon use

I'd be annoyed as well. It would just be shameful if it was only one product and an unfortunate spec error, but considering they have 2 larger sizes that are also quoted at 10.5 and 8.5 oz respectively…that seems like purposeful misinformation to garner sales.

If you want to give them the benefit of the doubt, you could contact the customer support and see if maybe you got a bad batch or something and see if they will somehow help you get down to the specified weight, but as a consumer that did your research, I tend to fall on the side of "don't cause me unnecessary hassle."

I would return them, if nothing else than for the seeming dishonesty. Put your money to a company that does a more careful job of monitoring the quality of their product (outsack has a quoted variance of +/- 0.1 oz from quoted weights and grubpack has an absolute max weight for their product).

DISCLAIMER: It pains me to advocate against a local AZ small business, so I'd probably temper my response more and contact Armored Outdoor Gear, but as a whole this shouldn't be necessary for such a simple product.

I'm pretty sure that you can rent them from the store in Grand Canyon Village. Also you can usually get free left over fuel canisters from the backcountry ranger station by the train tracks. If you don't use one or something similar (I've used a cookie tin), the squirrels and ravens WILL get your food.

>> I'm spending a lot of time and money to lower my base weight and those 3.5 ounces (per sack) seems huge to me.

It is, especially when competitive products weigh a lot less.

How many people days do you need fit in the sack? Because even the smallest Ratsack is pretty big for a solo trip.

I have a huge one that's 18"x20" that I take for a group. Big enough for 4 people for 4 days. It weighs 8oz. (It's a no-name brand one that someone made one test batch of.) I also have the smaller UL Outsaks for solo/2-person trips. The "micro" size (about 3oz) is big enough for 4 days solo for me. I take freezer bag meals.

Btw, I would suggest using a stuff sack inside the mesh bags. (I made silnylon ones with the exact same dimensions as the Outsaks.) If you put ziplock bags directly into the mesh bags, the mice do manage to get little nibbles of the ziplock bags. Not enough to get to the food but enough to put small holes in the bags (which you don't find out until you pour boiling water into it…%$&@!) A nylon stuff sack is enough to prevent that. It's handy, anyway, and keeps your food dry and dust-free. Make sure you put your food bag well away from where you're sleeping.

I am a bit ashamed of myself for coming to BPL to rant before contacting Armored Outdoor Gear. After I posted here I did send them a polite e-mail asking them if this was an unusual case. As of this morning I haven't heard back from them.

I have checked into renting them at the Grand Canyon. The rental is $7.00 a night. I need them for 5 nights…they cost $36.00. I think buying them is the prudent choice.

I bought 2 bags, one for my hiking partner. We will be spending 4 nights in the Canyon. Perhaps having 2 bags is overkill, but there will be future trips to use them on as well. Thanks for the other insights.

After sleeping on it, I'm going to wait a day or so and see if Armored Outdoor gives any response…if not I'm leaning toward returning the sacks and buying one of the other brands.

Just as an FYI, Ratsack was the original metal mesh bag. Came out in the late 90's, made in Flagstaff, I think. They started selling them at the general store in the park and sold mail order/online by the Grand Canyon Association. There were supply issues a few years ago; people weren't getting their orders and the store couldn't keep them in stock. They seem to have addressed whatever issues they were having but communication hasn't been their strong suit.

The larger UL Outsak would be nice size for you for 4 nights, with room to spare in case you want ever want to put toiletries in there as well. It's 10.5" x 19.5" and 3.75oz (by their spec.) If you keep your Ratsack, I bet you can get both of your food in one sack for this hike.

I've only backpacked the GC once so take this for what it's worth, but an Ursack Minor worked just fine at Hermit and at Monument.

Grubpacks seem to be better on their stated weights.

Bought mine several years ago in preparation for a Grand Canyon trip. It's the smallest size. Remember at the time that I was kind of annoyed because it was considerably heavier than specified. Just brought it out again and dropped it on the scale – 10 ounces.
On the plus side – they do work really well. My first night in the Grand Canyon the little critters came out at night and attacked the bag. No food was lost, but the little label that said Ratsack got chewed off. So you definitely need something to protect your food.

I also have an Ursack Minor. It weighs 2.625 oz.
I've used it kind of a lot in the GC. Perfectly fine for critters.

Outsak is the only mesh bag available at Grand Canyon and surrounding retailers. We've been the exclusive supplier for 5 years (since 2009). It is a privilege.

Be sure to hang Ursack Minor so the critters can't work on it. They will be able to climb onto it, but if the fabric has "give" they have a harder time. If they can work on a taught bottom sitting on a branch or the ground, and they are determined, they will get through. This is "one of three" for me.

From the Ursack FAQ: " Sometimes mice can chew very small holes, but very little of your food is likely to be taken."

I don't care what they take. I care about what they leave.

Be aware that mice can still get to your food through these mesh sacks when only in a ziplock bag. It happened to me at Boucher about two weeks ago. I may look into a liner of tyvek and/or hanging the sacks.

Mice and rats can chew through anything given enough time. As Greg said, you have to make it hard for them. Since their teeth are constantly growing if they aren't wearing them down fast enough they will chew just for a diversion – a kevlar sack full of food that might take it hours, and a comfortable perch, is probably a win-win for them.

If you have ever had any direct experience with rats this will not surprise you. I worked for a while in an electrophysilogy lab where the had imported some extra big ones, I think from South America. If given enough time those guys could probably chisel their way out o a bank vault. My ex wife had a very friendly (much smaller) one one we loved, but that guy could chew through anything if it had the least motivation, and by that I mean any time it wasn't eating, sleeping or grooming.

Don't COUNT on being protected from all hungry pests with any type of bag, including a mesh sack. While the mesh sacks do slow down rodents, ravens are able to destroy them and get your food in minutes…and Grand Canyon ravens are notorious! Very smart, very skilled, and very determined, I have seen these birds unzip someone's backpack and root around for food. Not kidding – wish I was.

We have now switched to cookie tins if we must cache our food; if it's just for overnight storage, a good airtight dry bag, hung in a tree (or from a pole stuck into a rock crack if there are no trees around) should be fine against rodents. Ravens don't generally operate at night.

Dave has already seen this, but it's a good warning — here's what a raven did to my buddy's mesh sack:

"Very smart, very skilled, and very determined, I have seen these birds unzip someone's backpack and root around for food."

You can see this almost every day at Bright Angle Campground at Phantom. Folks pack up, then decided to go for a short walk. Within seconds a raven swoops in, attacks a zipper, and the mayhem begins…

I love my Outsaks. Although it seems like Valerie's ravens can mess things up pretty well, the racoons, foxes, and skunks in my neighborhood don't. I chose to make 1.0 oz. cuben drawstring liner bags to add some security to my Outsaks. I actually did some tests with one of Lawson's 1.43 oz. small roll-top cuben bags, and nothing could bite through that burly cuben to get to the open can of a Fancy Feast cat food. I think that my Outsak/cuben liner combo will foil all but a bear, and of course Valerie's ravens. There aren't any orangutans or chimps where I hike.

Here's a photo of my end product. The one on the right is stuffed with 3 days worth of food, and it also has a reflective mylar liner, with the cuben one inside that. Last summer the chocolate and cheese got messy when the bear hang was in the hot sun, and I want to see if the shiny mylar might help with that. The one on the left is just an Outsak with a cuben liner.

LOL, good thing you're not using those in Grand Canyon, Gary. Ravens are especially attracted to shiny things! "Stealth" is definitely better with those smartie-pants ravens.

Yeah, Valerie, I wonder about that. I know that barracudas like to nibble on a snorkeler's gold earrings. I haven't done one bit of field testing on the mylar, as I made them over this past winter. I'll be pretty grumpy if I catch a griz playing tetherball with my food bag in GNP this July. We'll see…I've had more than a few "great ideas" get blown out of the water when tried out in the field.

I think shiny stuff will attract some critters, but repel others (too scary)… not sure what the bears will think!

>"We have now switched to cookie tins"

Ooh!, I like that! Metal, chew-proof, reasonably waterproof. Reasonably lightweight. And cheap. Like $1 at the Thrift Store with a Currier&Ives Christmas scene on it.

Genius. I wanted to mention Gary's post on burly cuben and rodents. This is backed up by others, including a reference, I believe, on one of Wired's trail journals. The 1.X oz. cuben is durable, I am usually hanging mine, so I don't, but maybe next trip to point reyes I'll stake it to the ground (so the coons don't steal it) and see how it fares. Time I called Zpacks for a new one anyway. Food for thought, though.

Funny thing, @greg23 (well, it wasn’t at the time) – I have a picture almost exactly like yours!

I just used an Ursack Minor for the first time on a trip to Havasupai (south side of Grand Canyon). First day using it, campground squirrels chewed through my bear-bag line where it was tied off on a tree to drop the food bag, then chewed a golfball-size hole in the Ursack, the “odor proof” OPsak liner, and several bags of food while we were exploring waterfalls. Do NOT use an Ursack Minor as your only protection against rodents!!! Luckily for me, I had brought some extra food and was with a group. Funny thing – my wife’s food Ziplocs were in the same bag, and they didn’t touch any of hers.

So even if I hang my food, some rodents are well-trained and will apparently chew through a hang line.  Everyone in my group had their backpacks hanging and the lines were chewed through on ALL of them. So even if I thread the hang line through a pie tin or bucket, they can just bring the whole system to the ground and bypass the shields. I’m thinking of using small steel cable to tie off my line to trees.  Hopefully it will take them a while to chew through that!

So if anyone has experience or reasons to choose of the stainless steel mesh bags over the others, please reply and let me know.

I’m not surprised to hear that the critters at Havasupai have learned to get “secured” food.  Again, Grand Canyon animals are not like others!  Nothing short of a cookie tin (or a heavy-duty ammo container) can stop them 100%, because they’ve been rewarded too many times in high-traffic areas.

Deep in the backcountry, the rodents aren’t that smart (yet); but the ravens can fly long distances from the Rim, and they are very, very clever, indeed!

While the Danish cookie tins are great volume/weight (and can be picked up any office for free after their vendors give Xmas gifts):

If you don’t need as much volume, Pepperidge Farms cookies come in a smaller one for $4.50 (or free if you plan to eat the cookies or go dumpster-diving at the recycling center):
