The Krimson Klover Drifter Top is built with anti-odor technology that holds up through repeat wears on a multi-day trip, so it doesn't need a rewash after every run. Moisture-wicking, UPF 50+ fabric with 4-way stretch handles a full day of activity, while a quarter-zip closure and stand-up collar give it a clean, secure fit. An all-over novelty print adds personality to a slim-fitting layer built to work as hard as it looks. What Our Gearhead(R) Experts Are Saying:"I wore this three days straight on a ski trip without packing a backup, and it never started smelling the way a normal base layer would by day two. The quarter-zip is what I reach for first when I need to dump heat on the way up a bootpack."
