These slings weigh a fraction of old-style shoulder lengths. It's great to be able to grab 10 of these when you start up a pitch, and feel like you are carrying almost nothing. One of my favorite pieces of gear, for sure.

Got wild one night on the internet, pulled out the credit card and ordered a bunch of these. It changed my life forever...I've been so happy since I switch all to Dyneema. This stuff is space age technology, space shuttle stuff! So light they seem to float.

These are light and supple. The long ones make a great personal anchor, and you can extend to the full length just in case you find you need it once you're on the rock!

Superthin at 8mm, solidly stiched (as it should be) and the overlaps are covered and smooth.

These are great all purpose slings at very low weight and bulk. They make killer alpine draws (way less bulky than nylon when doubled), but I get the most use out of the 180cm that I keep tied in an equalizing quad. Makes setting up belays off of two bolts a snap and is strong enough to hang you and your truck. These things are really great for everything, as long as you keep their limitations in mind (these things are skinny, so you don't want them rubbing against rock or sharp edges. Also, even though the jury is still out on this one, you should probably never girth hitch these to other slings).

These slings are great for eveything. Light weight, easy to manipulate, perfect for long draws and anchors...can't get enough of these.

Not only are these light and strong, they're also smooth as silk. I've made a few extendable draws with these and I couldn't be happier. Grab a few if you can.

These are super light and strong. They hold up very well in winter and summer conditions and stay very pliable. Great slings all around.

Best sling I've seen and used out there. I've got 3 of the 120cm's for anchor building and long extensions and 15 of the 60cm's as my primary extendable slings (replaced all my dogbones). They are light, very light. The weave holds up great to abuse (no snagging), and the end connection is great (see the pic in past reviews, explained very well). It essentially feels like a continuous loop, which makes racking much easier. My 2yr old slings look brand new despite hard use from the Gunks to AZ to Thailand.

I use the 60cm sling for all of my extendable draws. They are lightweight and not bulky, but the Mammut label on the slings is a bit of a pain when you are tying them off. Although most of the time it's just a minor annoyance that is easily fixed.

Holy cow! These are freakishly thin and light. I used to be a die hard spectra guy, but these changed my life. Replace all you old ratty slings with these guys. You wont be sorry.

light...strong...reliable and cheap...grab a few and add'em to your asenal...some of the best runners/slings around

super light take up no space on rack label is key helps slide over stuff way better without the normal lip

Hard to beat. These are the best slings I've used because they're thin (8mm) and so light.

As everyone has said - these are amazing, but don 't switch all your slings over. Depending on the rock and route, keep a few bulky slings on your rack for placements that will encounter edges. If nothing else, it feels good to know you have a lot of nylon running around that nasty edge.
