Condition: Lightly worn, thought it would be a better fit for me as I am usually a medium, but it has a tight fit.  Wish I went a size larger when purchasing.  One of the welded seams (pictured) in the inside split. It won't effect any functionallity of the waterproofing as it is in the inside of the jacket.  Willing to ship to buyer for cost of shipping.

Description from Patagonia:
Years of tinkering and refinement culminate in the M10® Anorak, our ultralight 3-layer alpine shell jacket, representing the optimal balance of minimalist design and protection essential for the most critical high-alpine objectives.

For climbers obsessed with shaving grams and streamlining their systems, our M10™ Anorak embodies the ethos of single-push perfection—when efficiency matters and actions have consequence, you don’t care if a pullover musses your hair. We took our most minimal alpine shell and honed it even further, with a trim half-zip silhouette that won’t pooch in the belly and ensures you can see every dime edge and verglas smear. Its engineered pattern eliminates seams from the shoulders and back panel, reducing points of failure and enhancing the modest stretch of the fabric. The Anorak is built with an ultralight, 3-layer, H2No® Performance Standard waterproof/breathable nylon ripstop with a DWR (durable water repellent) finish. Ultrasonic-welded seams are reinforced with narrow seam tape for superlow bulk, and the helmet-compatible hood with laminated visor and single-pull adjustment rolls down and stows with a simplified cord-and-hook design. The exterior left-chest pocket closes with a coated, watertight zipper, and the jacket self-stuffs into its chest pocket (with carabiner clip-in loop). Ultraminimal cuffs seal out weather, and a single-pull drawcord cinches the hem.
