This is a size L Dune (sand) half-zip made with Alpha 90 from Senchi Designs in the US. The material is Alpha 90, which is not as see-through as 60 and not as thick as 120, making it easy to wear both on the mountain and in the city. Alpha material is easily snagged when worn as an outer layer, so it's mainly intended for use as insulation. However, earth-tone colors like Dune are easy to match with recent outdoor clothing and have been very useful. There is one instance of a fiber protruding near the right shoulder blade on the back (see photo). I'm not sure if it was snagged, as it's on the back, but I think it came out during normal use. It's a type of fiber loss, which is the fate of Alpha material. There is no hole. A Senchi signature laundry bag is also included (unused). I like Alpha material insulation and have several pieces that I rotate, so I've worn this one less than 20 times. I haven't used it on mountain trips. This is not a current model with thumbholes and long, baggy sleeves. I also use the current model, but I'm honestly afraid to use the thumbholes on Alpha material due to the fabric's strength, so this one is simpler and more convenient. Other than the fiber protrusion on the back, there are no particular concerns, but it is a used item, so those looking for like-new condition should avoid it. Instead, I've listed it at a reasonable price, so it's highly recommended for those looking for insulation to wear over something else when hiking, mountaineering, or wearing it in the city. palante mountainlaureldesign 山と道 (Yamato Michi) three montbell omm hyperlitemountaingear ULAequipment rawlow mountain works ロウロウマウンテンワークス (Rawlow Mountain Works) アークテリクス (Arc'teryx) answer4 ノースフェイス (The North Face) 山と道 (Yamato Michi) ハンガーノック (Hangernock) ナイキ (Nike) パタゴニア (Patagonia) ブリックブラック (Brick Black) マウンテンマーシャルアーツ (Mountain Martial Arts) パーゴワークス (Paago Works) patagonia MMA salomon one ULTRA topo Gender...Unisex
