Highly insulated synthetic jacket, perfect for outdoor activities. - Brand: patagonia - Size: S - Color: Blue (Endless Blue) - Features: Lightweight, synthetic fiber, PrimaLoft Thank you for viewing. Purchased last fall at a Patagonia authorized dealer in Kanda. (Retail price: 33,000 yen) Worn 3 times, used for cold protection at the summit and as active wear during winter mountaineering. Despite being synthetic, it feels warm immediately upon wearing, and I feel incredibly secure in its insulation. There are no scratches or stains, and I always maintained it after returning home, so the condition is excellent. It was a product I really liked, but I'm selling it to minimize my gear. For reference, my height and weight are 179cm and 67kg, a slender, muscular build. Nano Puff size S was the best fit for me. Patagonia sizing can be tricky, so please use this as a reference.
