Comfort meets top quality materials. Walking Jack CORE COLLECTION offers underwear that lasts and can be worn every day and at any time. We have tested and chosen high quality fabrics, threads and waistbands to make undergarments that retain their shape and are strong enough to withstand an active man's lifestyle. The comfort our styles offer is combined with a new take on classic underwear design. We think this is the best underwear for men in the market today!
