It’s a lightweight short sleeve v-neck base layer in heather gray stripes. Made of a high performance blend of merino wool and nylon, the fabric is durable, sweat-wicking, and odor-resistant. Worn (has some minor pilling) but still in good condition and very functional. Comes with its original tag. About 18.5” wide and 27.5” long. Somewhat fitted, as is typical for a base layer, but fabric can stretch a bit.
