Popular Blue Monte product! I purchased this item and tried it on once, but it doesn't fit, so I'm selling it. The product tag is still attached, and it's almost new and unused. The stuff sack is also included. The photos of the actual item start from the 6th image. Color: Dark Purple Size: M Ultra-lightweight and high-performance. Next-generation insulation that fits your movements. Uses the high-performance material "PRIMALOFT ACTIVE EVOLVE" (95g/㎡). Due to its special fiber structure, it provides excellent heat retention, moisture absorption, and breathability, offering a lightweight and comfortable fit.
