Great harness - mixed sizing

This is a great ultralight harness & super versatile and comfortable (for what it is). Excellent functionality and some of the best racking on this type of harness. Super light and compact too. I prefer this to the Petzl Fly. That said - the sizing is off. I'm a 32" waist and based on Mammut's sizing chart I should be a comfortable medium. In reality I barley squeeze into the medium's hip belt. I have thick legs and the legs are fine though. Overall, I'd highly recommend this harness, with the caviot that folks should try it on in-store. Hopeful that Mammut can address the sizing issue, but likely plan to size up on this harness. Would be 5 stars, but for the sizing issue.

Excellent build quality and ridiculously light

I bought this for a very particular application and it is perfect. It is incredibly light and it barely takes up any pack space. It is as comfortable as you can expect from something in this category and has solid attachments for the minimal gear I carry in these situations. Plus, it's awesome to have a sub 2oz harness to toss around for emergency kits.

Don't size up

Other reviews have said to size up...this is not my experience. I normally would have gone with a medium (32" waist) but decided on large based on the other reviews. I cannot get this harness tight enough on me even with thick clothing on.

Sizing is way off

I have a 30in waist, all the pants I own are size 30. That is right in the middle of their recommendation for "small". This isn't even close to fitting, consider sizing up or even twice

Really nice

Good product but it would be cool to have a second material loop. That would't be that much havier

Super lightweight harness great for ski traverses. The sizing is a bit smaller than expected.
