One day you're hiking, the next you're climbing, and then hopefully you'll manage to squeeze a quick backpacking trip in over the weekend. Or, maybe your week is more work oriented with brief stints between the climbing gym, yoga studio, and trails near your home. No matter what adventure comes your way, the Ibex Women's Woolies 150 Racerback Tank Top is your constant companion. Merino wool wraps your core with temperature regulated control so you cool down when you work up a sweat and warm up when you chill out on the top of mountains. It's also naturally antimicrobial, meaning it stays fresh throughout your backpacking trip or under your workwear in winter. The form fit eliminates any bulk when you add layers over this top, and its racerback design allows the freedom of movement you need to pull past technical cruxes.
