Men's MTF4000 Crewneck
Regular price
$55.00
Meet your new cold-weather MVP: the MTF4000 Base Layer Top. Made from softly sanded polyester with a hint of spandex, it feels like cotton and delivers just the right amount of warmth—perfect for layering or rocking solo. Thanks to Moisture Transfer Fibers, it wicks sweat away so you stay dry and comfy through every move. Plus, with UPF 30+ sun protection, it’s ready for bright days too. Flat seams and a snug cut mean no chafing—only serious coziness and style from the base layer up.
Features:
- 89% polyester / 11% spandex
- Midweight warmth for versatile layering
- Moisture Transfer Fibers wick sweat to keep you dry
- UPF 30+ sun protection shields your skin
- Soft, cotton-like feel with stretch for unrestricted movement
- Flat seam construction for reduced bulk and chafe
- Active fit silhouette for comfort layering
Best For: Sunny, chilly days for sun protection, cold-weather hikes and camping, outdoor workouts and training
