Recommendations for bags that fit in crash pads

I looked through all 16 pages of Bouldering and didn't see a topic on this, but if one exists plz feel free to just link to it here

Any recommendations for decent-sized bags that can be easily stuffed in a folded (bi-fold) crash pad? If I'm taking enough stuff to justify a bag, I usually wear a backpack on the front. But that's not great for some approaches where I need to see where I'm stepping a bit better.

I know Metolius made such a bag once. I've seen this one from Power Company and this one from Tension…any others I should be aware of?

I know Asana makes what they call the "dirt bag" that has loop handles for this, and they originally advertised it for this purpose, but the website lists the pack and not if its for use inside a pad still. 

You can commission me to make something custom or make a copy of the metolius bag. Let me know. 

I have a Boulder Roll from Organic that I carry inside my pad and I really like it because it's large and flat so if you lay it inside the pad before closing it the weight of my stuff gets spread out i side the pad.

Here is another one: https://mountainmethodgear.com/products/boulder-caddy

Ikea zip bag.

Works really well and costs $5. Holds lots of stuff and packs flat in the pad. Has a zipper to keep everything contained (as opposed to the non-zip basic Ikea bag). Wide zipper makes it easy to access everything once you pull the bag out. A lot more durable than you'd think. 

I've had good luck with an old messenger-style work bag. Opens flat, has enough space for almost everything, and can carry over the shoulder when needed. I added a couple of velcro straps to the outside to hold shoes.

I hate walking with a backpack on the front so I always use the bag-in style. I've used the arcteryx index 10+10 for about 5 years or so and it works great. Basically it unzips open to make it thin enough to fit in the crashpad, and you can also zip it up to carry separately.

Thanks for the recommendations, everyone! Appreciate it!

rei flash 18 does it for me

Cotopaxi Batac is nice, that’s what I’ve used for awhile 

Wanted to revive this thread as I have been looking in to bags like this for the last year and was about to start a slightly different thread.

Currently use a Cotopaxi Allpa since I like the zippered compartments to keep my shoes separately and since it's a clamshell design to place in between pads. I switch between a 28L and 42L depending on if I'm packing for myself vs +1.

I'm really interested if anyone has personal experience/review of the Tension aux backpack. It looks like a pretty ideal bag with multiple compartments. 

Buddy of mine has the Mountain Method caddy listed above that I got to see in person and really like it too. Between the two, I'd probably get the caddy since I have enough backpacks for general use and wanted something specific for the crag. 

I have the Mountain Method caddy. I do like the fact that it does pack pretty flat so that if fits really well inside the pad without the characteristic bulge that you get from other packs. The main issues: Each individual shoe being in its own pocket makes packing up slightly annoying and more time consuming than it should. Also the water bottle pocket doesn't actually fit a standard 1-liter nalgene bottle. I was thinking that the Tension Aux might be better on both of these aspects, although I don't know if it packs as flat.

Ahh, I didn’t think about the only one shoe per pocket. Seems like a small thing overall but I can see how it’d get annoying over time.

I think I do like the tension backpack the best, just don’t know if it’s worth the premium price over other stuff I have currently that works almost just as well. Or like the MM caddy that’s half the price.

I have a small bag that I originally bought for long multi-pitch but fits perfectly fine inside pads.

Perfectly holds my shoes, chalk bag, water bottle and a few snacks. Not space for much else.

Y'all are really sleeping on the Ikea zip bag.  Can't beat the price at $5. Can easily fit a full day of kit - water, lunch, layers, multiple pairs of shoes. -- yet still flattens down in the pad. Shown here packed in an organic simple pad.
