how does it fit you? i am about same hieght 165 lbs . 5 ' 9" with boots on .

. i was at manufactureres web site just now . my device it to big for me . it is uncofortable when tightened down , like i can not get good air flow if i paddle . yours may be a little small for me? does it fit you ok? i was slender build when i was younger. i am still slender build for over forty , especially being an American ( hooaah ) in a country that a high obese percentage.

. thx for input.
