Icebreaker Siren Bikini Women XS / Black
A pair of knickers so soft, you won't even feel like you're wearing any. The merino/nylon & core-spun lycra fabric offers next-to-skin softness, whilst providing comfortable warmth, in addition to strength and durability. The bikini design provides a modern and bulk-free fit - exactly what you want out of your underwear. These practical underpants feature forward side-seams and comfortable leg/waist openings to eliminate chafing and uncomfortable rubbing. You can wear these undies under absolutely anything - from activewear to everyday denim. An ultralight 150gm blend of merino, nylon and core-spun LYCRA offers comfort, durability and a full range of motion. Built from 83% merino wool, 12% nylon & 5% core-spun LYCRA. Ideal for everyday use as well as yoga & studio, hiking, travel and lifestyle. The merino naturally resists odour, regulates temperature & manages moisture. Slim fit. 32 g / 1.13 oz.
