What size compression bag for a Marmot CWM MemBrain 800 Fill Down sleeping bag (Long). I tried a 35L sack but it was a long hard wrestle! Is 50L too much?

Responded on

Jim,
While a 45L stuff sack would probably work for you, the 50 in a Granite Gear Round Rock Solid Compression Sack could be great too. The Round Rock Solid sacks have a compressing lid that will allow you to compress the contents down no matter whether it is a tight or loose fit (within reason). The versatility of these bags is their greatest feature, because as long as you are within a decent range, you can use the compression lid to size down the load.

Hey,

That's a wealth of information, but I'm showing the stuff size for the Sorcerer at 18x8.5", so let's use that to start. That would put you in a 16L Rock Solid. The rule is to get as close to the original stuff size for the bag as possible, then, especially with synthetic fills, consider more compression as a gift. Too small to begin with, and stuffing your bag becomes a constant drag.

I have a sleeping bag with dimensions 38" X 81". What size compression sack would i need to fit it. Thanks

Hey Lawrence,

We unfortunately need a little more information than the unrolled dimensions to get a real clue on what size stuff sack you need for your sleeping bag. What we really need to know is the stuff size of your bag. Most likely you are going to want the 9L or 11L bag but that's really going to depend on a lot of factors like whether you bag is down or synthetic. Is your bag a 30 degree bag? Or is it a sub-zero bag? If its down, whats the fill power? If you could let us know the make and model of your bag we could probably narrow that down for you and let you know exactly what compression bag to get.

I am looking for a compression sack for a sleeping I just purchased that I will be taking with me on a trek into the Himalayas this coming fall.

I am not sure what size of a compression sack I would need.
Some information about the sleeping bag I just purchased is as follows:
Packed volume 10.1 L
Length 168 cm
Fill = 575 fill-power duck down + Hyperloft Eco
Does this mean I would need an 11 L Granite Gear Round Rock Solid Compression Sack?
Any information you could share with me would be great. Thanks!
Charlene

Hey Charlene,

The average stuff-sack that comes with most sleeping bags is right in the ballpark of 7 x 17 inches. You could probably get away with going with the 9L compression sack but I think you are probably right, the 11L will probably work best for your bag.

Best Answer Responded on

Hey too Charlene,

Rule of thumb: start with the stuff sack size that comes with your bag to get your compression sack sizing. So with a 10.1L, yes, you'll want the 11L Rock Solid. Great comp sacks...a real staple around here. Hope this helps.

Awesome Compression Sack

  • Familiarity: I've put it through the wringer

This thing is great! I've had it for a few years ago... use it primarily for compressing my old school Campmor 20º down bag. The XS is perfect for this, getting it down to a package only a bit taller then a Nalgene (is that an international unit yet?), though it is obviously a bit thicker then the Nalgene.
My friends are often blown away when I pull a full sleeping bag out of such a small bag. Super durable as well, I crank it all the way down, and it is yet to show any real signs of wear. Wish it was waterproof, but I guess you can't have everything.

Tough Stuff

So far, this is the sturdiest stuff sack I've been able to find. I hope to get many years of use from it.

the 9L and 11L are 15in and 17in respectively....

the 9L and 11L are 15in and 17in respectively. But how small do they actually compress? What is the size you can get them down too?

Best Answer Responded on

That's subjective and depends on what it is you're trying to compress, ie: down, synthetic bag, tent, heavy clothing, wool socks...
Rule of thumb though: if the gear in it cooperates in some perfect world scenario, plan on having a cylindrical wad about 1/3 the size you started with.

What size would be good for the marmot...

What size would be good for the marmot limelight 2p tent (body, footprint, fly)? The packed dimensions of the tent is 7x21, so minus the poles I dont know what size compression sack to use.

Best Answer Responded on

The Medium on this one,too. aka 16L, aka the red one on its side in the picture. As much as you might want to go smaller, this one will be less of a fight, and you'll run out of compressabilty on the tent before you run out of strap to compress it with.

was asked to get a 15 lb compression bag....

was asked to get a 15 lb compression bag. Yours are listed as 11L, 16L, etc. Does the L equal Lb? If not, which is closest to 15 Lb. He already has a 20 Lb bag

Responded on

The L stands for Liters - how much it will hold. You typically want to size bags by volume, not weight. I'd recommend checking the dimensions in the tech specs box (above and on the left of the page) to figure out what size you'd want.

Great sack!

I haven't gotten a chance to "get out" with these sacks but since I got them a few weeks ago, I have stuffed and compressed everything imaginable. They seem very strong and well put together, you can reef of them and not worry about tearing something. All in all, I'll be buying more. I was also able to get my Mountain Hardwear Lightpath 3 (body, fly, footprint) in this thing and squish it down to nothing.

In the picture is the XL with 3 sleeping bags.. Sierra Designs Arrow Rock 30, and 2 SD Big Dog 35's. It took some effort but I think it did a great job.

Great sack!

Excellent

These are like little miracles. I am traveling with my pack as my luggage on two weeks in Central America and it is amazing HOW much room I have saved with these packs I even have room to spare. Though they are difficult and/or darn near impossible to compress to a 1/3 of the size of their original size, packed, they still compress easily to 1/2 of the size.

Does the job

It seems pretty sturdy. I got a 16L to store my 10 year old synthetic bag that is neither light nor small/compressible.

It goes in extremely tight and with compression I thought maybe I would pop the seems but its holding just fine.

Compression in that one only goes down perhaps 1/4 but that obviously depends on the bag.

Id buy one again. Great price, decent product

Densify your body tortilla

This is a must for anyone lookin to pack their sleeping bag in the smallest nook of their pack. I have the M 11L and it's perfect for a 650 down Regular size sleeping bag. I'm naturally tough on gear and after cranking down on these compression straps and pounding this thing into the small voids of my pack, its still beggin for more

So I need a way to pack 3-5 days of clothes...

So I need a way to pack 3-5 days of clothes and make it as small as possible. Can these bags work on clothes? If so what size should i be looking for to pack that amount of clothing?

Best Answer Responded on

Oh man are they ever great for clothes! Depending on how you're going to load your pack, you can compress it down into a tight bundle, or just use it to keep everything together, but still stuff the nooks and crannies. For what you need, I would go with the large. These comp sacks are fantastic. You'll be hooked the first time you use it.

Responded on

Yeah, they'll work for clothes. Depends on what type of clothes you have for sizing. If it is mostly down and highly compressible stuff then you might be able to get away with a medium, otherwise go with the large.

Stuff It

Great stuffer. I can fit a weeks worth of clothes into the large bag and have plenty of room for other gear in my pack. Rugged material too, and makes a good pillow in camp!

How do these Granite Gear sacks deal with...

How do these Granite Gear sacks deal with wet conditions? Are they waterproof at all?

Best Answer Responded on

I wouldn't recommend using them for a canoeing or rafting trip down the river like a dry sack, but they will work fine in any other damp or humid environments. They are water resistant not waterproof.

Responded on

To add to that, the material used in the Granite Gear Round Rock Solid Compression Sacks is waterproof (PU coating), but the seams are not. They are taped (not the same taping as in a waterproof jacket) which helps them from fraying and allows them to be more water resistant. However with prolonged water exposure, the seams will draw in moisture.

Granite Gear does offer a more waterproof compression sack that is fully seam taped (waterproof taping). These are the Granite Gear EVent Compression Dry Sacks. These are significantly more waterproof and feature a roll-down closure, eVent material on the bottom of the sack to allow for purging of the air, and every seam is taped for maximum waterproofness. I would recommend using these if going on a trip that will likely involve large amounts of water exposure.

Gotta Wonder

I too feel obligated to offset the mediocre ratings. This compression sack works great. Pulls enough volume out of my rather dated synthetic summer bag to allow for an extra layer of clothing or an extra liter of water. Hasn't so much as threatened to let me down.
