ARC'TERYX Arc'teryx Cormac Crew Long Sleeve, Men's, XL size. It's thin and fits well, so even XL doesn't feel too big. I think this might be better than the L size for those who prefer a looser fit. (This is just my personal opinion.) Dimensions (approx.) Length: 74cm Width: 63cm Shoulder width: 49cm Sleeve length: 69cm No pets, no smokers. From the official website: Provides excellent protection and UPF 40+ sun protection, perfect for trail running and high-intensity activities. Designed with runners in mind, the Cormac is a versatile item that can handle any high-intensity mountain activity. It cuts out UV rays and provides a comfortable fit backed by high functionality. The moisture-wicking, breathable 100% recycled Phasic™ LT material has UPF 40+ sun protection and is also odor-resistant. Maximizes breathability, and the body-hugging fit and thin collar make layering comfortable. The seam design minimizes friction. - Brand: ARC'TERYX - Size: XL - Color: Dark Blue (Nightscape Heather) - Design: Long Sleeve - Material: Polyester Please refrain from price negotiations.
