The lightest of Ibex's long sleeve base layer offerings, the crew comes in solids & stripes so whatever your mood, it can fit the bill. The cleanly designed 18.5 micron fabric looks great paired with shorts after a long day outside or layer it up as summer sneaks into fall. (We're told these things also get used in the winter.) 150 grams / m sq fabric is versatile, odor resistant and ready for adventure.
