Cool, comfortable and breathable in super-soft bamboo fibre, these 3 Pack Jeff Banks Plain Bamboo Trunks are stretch jersey men’s underwear that offers all the benefits of that skin-friendly, planet-friendly sustainable wonder fabric. Bamboo is naturally antibacterial, non-irritating even for sensitive skins, thermoregulating, and three times as moisture absorbing as cotton. Topped by a Jeff Banks-branded, soft-brushed elastic waistband, these mid-rise trunks have a double-layer front pouch, and a sewn-in saddle panel seat that helps resist bunching in the back. With 5cm inseam legs and strong, chafe-preventing flat overlocked body seams throughout, the trunks have a tagless care label system, designed to stop irritation.
