My new favorite biner

I've put it through the wringer

I like the way it looks, it clips very nicely, excellent prices for the quality. I own 15 now and as long as they make them I doubt I'll buy any other carabiner.

Sleek Carabiner

When it comes to carabiners i personally think this is one of the better looking ones. Not only that but it is strong. I'd feel comfortable taking a fall on on of these any day. The heat forged design is awesome. I bought these for alpine draws. They're not too bulky and do their job just right.
