Great service and the underwear is brilliant. I walk a lot for my job and used to find my old boxers would rise up making them uncomfortable and causing some chaffing but these stayed where they were all day and were really comfy.
Really excellent products bought for my two active teenage boys - they won’t wear anything else. Customer service are really helpful and great to deal with
This is my 3rd order of STEP ONE! they are simply the most comfortable. The glide slide inner thigh and comfort pouch are the magic ingredients to coming back time and again!
Superb quality and an excellent fit, I will only ever be ordering these trunks in the future.
