    Dust-proof, chalk-proof closure system that's easy to use.

    Arc'teryx gave its Small Aperture Chalk Bag the new innovative Aperture Twist closure system that allows you to open the bag quickly and easily while you're climbing. At the press of a button, this small bag expands in order to let you chalk up quickly and climb on, and a quick twist closes this bag once you've finished climbing. The Aperture Twist closure system works so well that chalk dust can't even escape, unlike most chalk bags. Polar fleece lines the Aperture to keep the chalk intact, and the included belt and brush holder equips you with what you need to send.

    Great bag for the price, small bag tho

    • Familiarity: I've used it several times

    Its a fantastic bag, exactly what i expect from arcteryx, but keep in mind it is small. I was able to fit one chalk shot in it without much effort. Its lightweight, has no pockets but does have a loop for a brush if needed

    Just a bit small

    • Familiarity: I've put it through the wringer

    I thought the closure was a bit gimmicky but I took a chance and tried it out for myself. It WORKS! I wish I’d gone with the large as I can be just a little harder than necessary to get into when resting mid route, but not horrible. I think I have a new favorite chalk bag...

    Functional Chalk Bag

      There isn’t much to a chalk bag, but Arc’teryx managed to make a simple design even more simple. The twist/buckle system keep chalk in the bag better than my other traditional chalk bags. It’s a very convenient design. I was looking for a small minimal chalk bag for sport climbing. The small size works great for me. I do need to fill with chalk about every other day of climbing.

      Nice lightweight chalk bag

      • Familiarity: I've used it several times

      I wanted a lighter and smaller chalk bag for outdoor / longer climbs and this product does the trick. Perfect size for my hands, and I love how it can be twisted closed to compact even more. My only complaint is you have to twist it one direction for it to close properly (I think it was counterclockwise?) If you twist it the opposite direction, it leaves a tiny hole in the middle and leaks chalk.

      Compact and dust free.

      • Familiarity: I've used it once or twice and have initial impressions

      Nice snap flap closure on this little bag. Really lightweight. Super compact. I'm a smaller guy and honestly I couldn't ask for a better bag.

      Compact and Clean

      • Familiarity: I've used it several times

      I got this as a second chalk bag for bouldering. It's simple, compact, and keeps everything clean. The only thing negative I have to say about it is this: to close the bag, you need to twist to the left, which is completely counter intuitive. (Righty tighty, lefty loosey, right? In this case, wrong.) I actually thought it was defective until a friend suggested I try twisting the other way. So in summary, excellent chalk bag, just make sure you twist it the right -- err the left way!

      Compact and Clean

      Perfect Chalk Bag

      • Familiarity: I've put it through the wringer

      I used to be apart of the crew that didnt really think you could invent or design a chalk bag better than others. Just bigger or smaller. Then I gave the Aperature a shot and it really is different, totally worth the extra $ versus other more generic bags.

      The Aperature or twist feature not only eliminates chalk from falling out but, it packs down smaller in the pack. Or it packs down smaller on your waist when you are not using it like when rappelling, not a huge deal but, does help keep it out of the way if you need to grab a biner off the back of your harness.

      Perfect Chalk Bag

      It's Arc'teryx yo!

      • Familiarity: I've used it several times

      I bought this to compliment my harness of the same brand. It does work. I wish it kept the chalk a little more contained. Overall good build quality though. Would recommend.

      Lives in my car

      • Familiarity: I've used it several times

      Just like Will said this bag is awesome! Neat and compact with no mess. I have 0 worries that any chalk is going to be getting in my car. The Metolius Super Chalk Eco Ball fist perfectly into this bag as well just in case you were wondering.

      Great bag - doesn't leak in the car

        If you're ever bothered by chalk getting all over the place when you throw your gear into your car, then this is a very good option. It seals exceptionally well, but also opens back up with just an unsnap.

        I personally prefer the small size of bag even with reasonably large hands. It easily holds a ball of chalk and saves on bulk.
