I widened the collar of the Uniqlo Extra Fine Merino Crew Neck to be used as an invisible undershirt. It's much warmer than Heattech and has moisture-wicking, quick-drying, deodorizing, and antibacterial effects. Since it's for an undershirt, I've removed all the tags. Because it's extra fine merino wool, it doesn't itch at all. On the contrary, it's soft and warm, and once you wear this, you won't be able to wear Heattech anymore. I highly recommend this instead of the Workman Merino Wool 100 long-sleeved crew neck. It's off-white, size L. I wore it for one season, and since I rotated it with other undershirts, I didn't wear it much, so it's in good condition. ■Size Shoulder width: 44cm Body width: 49.5cm Sleeve length: 61.5cm Length: 60cm (66cm from the original collar position. ← This is the correct measurement) UNIQLO Material...Wool Pattern/Design...Solid Sleeve length...Long sleeve Stains, tears, odors, etc....None
