Aspire – long boxer brief
I like the longer boxer briefs as long as you don’t pull them up too high because the extra material for the boys that’s built-in is a little lower than you might expect. But overall, it’s extremely comfortable and when it’s positioned correctly, the boys are very happy.

Very Comfortable
The long boxer briefs are very comfortable. They are very quick to dry and great for travel as they take up almost no room in suitcase and when travelling can get away with only taking a few pairs with you.

Best Underwear I've ever owned
I now own 5 pair of these in all different colors and these are by far the best underwear I've ever owned. The fit is perfect and it's like you're wearing nothing at all. Once the fabric adjusts to your body temp, it just molds around you giving you the support and comfort you need all day and through all types of activities. Can't wait for another opportunity to get a couple more pairs. Keep up the great work.
