The Walking Jack Bluebird Collection is a further step up in comfort than any other underwear in the market. If you liked their Core Trunks, you will love these too! The Walking Jack Bluebird Trunks feature an all blue design and are made from a top quality fabric, a cotton and elastane mix. The only two differences you will find from the Core trunks to these is that the waistband is longer by a few centimetres for a slightly looser grip and that the pouch is lined. Timeless style combined with ultimate comfort in a high quality garment for men, designed and made in Europe. These trunks are going to be your new favourite!
