This seamless long-sleeve tee is made from ZQ-certified 17.5-micron Merino wool spun with a strong filament core for durability and shape retention. Its knit design includes zones of compression and breathability for targeted support and moisture management. Raglan sleeves offer unrestricted movement, while thumbholes keep sleeves in place. A reflective logo adds visibility for low-light safety, making it ideal for demanding activities.
