This "outdoor T-shirt" features a pen Pocket on the left sleeve, similar to those found on flight jackets, and a drawstring at the hem for tightening. It uses air-spun yarn for a rough, dry texture. The thick, durable Tenjiku fabric makes it perfect for outdoor wear. The large Pocket are also a highlight. While the daytime heat is comparable to summer, it suddenly cools down once the sun goes down, making this a perfect T-shirt for late summer and autumn.
