Familiarity: I've used it several times
These Bibs are lightweight, tough and versatile. I've used them while skiing with only a layer of wool under, they are very flexible and have great breathability. At about 6' 2" and 200 lbs, I found the Large to be the perfect fit. These bibs will also be my first choice when trekking/going backcountry trough all four seasons when the weather is demanding. Also, the full length leg-zippers is ingenious. What more can you ask?
