I really wanted to like these because of the fly - which is awesome - but otherwise, they're not a success. The fit is a bit too tight, and they developed a hole in the front after one wash (I did follow the care instructions). Skip these and go for another style.
Air Army Brief
The Jack Adams Air Army Brief is exceptionally soft, comfortable and like wearing nothing at all. Designed with our original horizontal fly for quick access when nature calls and our contour pouch nestle the boys for support. The Lenzing Modal material wicks sweat away and is quick drying. Perfect to wear under your business suit or your blue jeans, you will love the comfort! Made of 95% Lenzing micro modal and 5% elastane.
I first purchased Jack Adams briefs and was overwhelmed with the comfort and the ease of use of the horizontal fly. My wife was not pleased with the price but I have since purchased three additional pairs.
I wear suits all day long and run from meeting to meeting and these have become my favorite pair of underwear. Best part is the shape of pouch and the design of the fly. Makes things fast! Gotta say the feel of the material is also great.
