Size: M Gender: Men's This is an M size Indigo Night jacket, which is popular and sold out on the official website. It has been worn 5-6 times in one season and has been professionally cleaned, so it's in excellent condition. This is a lightweight and highly breathable active insulation jacket that also provides warmth. Its excellent breathability and insulation make it suitable for snow activities, as well as general year-round mountaineering and hiking. The outer fabric uses lightweight double-woven 20-denier recycled nylon aero100, offering lightness, breathability, and wind resistance, while also providing stretch for ease of movement. The jacket lining features Polartec® Alpha® Direct (not used in the armpits), which continuously releases excess body heat, providing excellent breathability during activity while maintaining stable warmth. This ensures insulation not only when actively moving but also when sitting. Please consider it. ◾︎ For those who like: ridge mountain gear Pa'lante Packs パランテ HIGHTAIL DESIGNS ハイテールデザインズ ENLIGHTENED EQUIPMENT Cumulus Mountain laurel designs senchi designs hyperlite mountain gear ハイパーライトマウンテンギア Zpacks 山と道 atelierbluebottle six moon designs シックスムーンデザイン Locus gear ローカスギア ハイカーズデポ Moonlight gear ムーンライトギア sola titaniumgear mikikurota ミキクロタ Gossamer gear rawlow mountain works and wonder Jindaiji Mountain Works Hillbilly Pot ヒルビリーポット Nruc Akihiro Woodworks Jincup Vivobarefoot OMM Mountaineering Trail running Fastpacking Ultralight Dyneema DCF Merino wool Polartec Octa Alpha Direct 250 UL
