About this part
The MSR Performance base layer shirt, the top half of the base layer set, designed for warm to hot weather riding. The slim fit is what lets it layer under a jersey and a chest protector without bunching anywhere.
The fabric is 100 percent polyester with four-way stretch, fast-drying, breathable and anti-microbial. The seams are low profile so nothing rubs under a chest protector, the garment is tagless, and the fit is athletic. Six part numbers are listed. The matching base layer pant is a separate listing if you want the full set rather than the top on its own.
