It's about a size S in Japanese sizing. A perfect fit for someone around 165cm and 65kg. The TITANIUM series features Columbia's unique waterproof and breathable material. I used it for skiing on the 3rd floor, but I'm selling it because the size no longer fits. The condition is still good, with no noticeable tears, and it's still usable. Measurements are approximate due to being done by a layman.
