The two-way collar on this Aircon V-U-Neck 2 In 1 Tank Top is genuinely useful — I wear it as a V-neck for workouts and switch to the square neck for casual days. The ice hemp yarn feels cool against the skin and breathes well on humid city walks. After several washes there is no pilling, fading or shrinking, and it barely wrinkles when packed. Sizing runs true. Good basic for both errands and weekend trails.
