This is an ARC'TERYX outdoor half-zip undershirt. Unlike compression types like Under Armour, it has a soft, fluffy fabric. It's from the era when the Japanese distributor was Sunwest. It hasn't been worn much, so there's no damage, but the yellow logo on the left sleeve has bled its color. Please check the photos for the condition before bidding. Measurements (laid flat): Length 63cm, Width 43cm. - Brand: ARC'TERYX - Size: M - Color: Blue - Design: Half-zip - Intended Use: Outdoor wear Thank you for looking.
