Never disappointed by Icebreaker

This top is perfect, but it is more preferred as underwear. Indeed, there elastane and so it is tight on the body. It remains comfortable. Why as underwear? Because it is thin enough (so lightweight and fast drying), but as it sticks to the body, each unsightly bulge shows. For the practice of a sport, better to choose a model without elastane. Icebreaker not specially small size. For my morphology (1.58 m and 48 kg), I take XS. Ditto for underwear and privateers / leggings.
