They are QUITE large. I chose the size based on website recommendations - I'm 5'9" tall woman, very muscular build with large hip/thighs and I feel a bit like I'm swimming in these which I did not anticipate - I could definitely put large winter layers beneath, so that's a bonus. I have the shoulder straps set at the very shortest length, and the pants still drag a bit on the ground so these are definitely designed for quite tall people, even at "standard" length. They are starting off super water proof and I'm hoping they'll be as durable as my Kaiwaka water proof pants I got years ago in New Zealand. Great quality build, but beware large sizing - I could easily go down to a medium I imagine.
