Trunks are particularly appreciated for their maintenance as a lycra swimsuit. An elastic at the bottom of the legs firmly maintains the trunks on the thighs. The thin elasticated waistband of these swim trunks is covered with the swimsuit's fabric. The ALIZE swim trunks can be tied with a flat drawstring inside at the front. Polyamide is a material which is particularly suited to swimsuits: It dries quickly and does not retain moisture, allows colors to set well and does not fade. It is a very solid and durable material and also flexible as well as resistant to friction. Elastane provides elasticity and comfort.
