Size Chart — Size Guide Mens Pajamas El Búho Nocturno

At El Búho Nocturno, a Spanish textile brand rooted in the artisanal tradition of the 1960s, our garments are designed with a roomier classic cut than the current standard.

Our men's pajamas, boxers and polos are designed to be loose-fitting and provide the comfort you need to rest.

⚠️ Important: if you are unsure between two sizes, choose the smaller size — our generous cut means the smaller size is probably the right one for you. If you have any questions, contact us and we’ll be happy to advise you, with no obligation.
