I have been in the service for 13 years now and have worn some silkies. I have had the loose ones and the tight ones but could really never find ones I really liked. I even bought some of the new Silkes from the PX before I bought these, and the material was rough, and I just did not like them. These bad boys have an excellent liner on the inside to keep the boys in place but still let them breathe. I have ran, swam, and gone to the gym in them. They feel excellent, and I will probably keep ordering the silkies from this site. They might be a little more than the silkies at the store, but they are worth it. They are a must-have, and I recommend this product, and if I could be a promoter for this product, I would.
