Comfy, smooth, amazigly functional

The material is great, moves fluidly and feels very light despite the length of the trunks, which is great. I actually went cycling with these at the first opportunity - I ride my bike a lot, and these felt absolutely great under my gym shorts! Not to mention they did a great job of keeping my dry and a nice temperature. Also, I have to say I absolutely love the H-fly! Easy access without being too exposed. The pouch on these is similarly great. If I had more money (and more drawer space) I would definitely be ordering more of these!

Excellent comfort and support

My comments would be as follows: 1. the waist should be slightly loser and lower 2. all underwear should be tagless!!

Love the style but...

I was really excited to receive my two pair of core cycle trunks as a first time buyer of JA products . The pictures are deceiving because of the relationship between the waist band location and your belly button. I measured my waist line 1 inch below my belly button and it said I was a size bigger than my normal boxers so I went with it since most of the time sizes arent the same for every brand. Needless to say they were too big - they rise all the way up to my belly button (awkward feeling). Just a good advise. Buy to size no matter what the measurements say. I love the cut but since they are too big they feel awkward; I shoud've just ordered 1 to begin. I think anyone would love them if they get the right size thats why I gave it 4 stars.

Love the pouch

Great fitting underwear! The pouch gives great freedom of movement while the rest of the underwear provides a nice amount of support. Extremely comfortable fit and finish. Provides for an extremely masculine look while highlighting my most important attribute!

Where have you been all of my life?

I'm afraid to think about the amount of money I've spent over the past two years in my quest to find the perfect underwear. Before Jack Adams, Andrew C.'s Almost Naked line was the only go-to underwear for me; but the colors and styles leave a lot to be desired, and the 'support' isn't exactly up to snuff. I thought I'd never be completely satisfied ... then I stumbled upon Jack Adams! JA's simple colors fit my personality perfectly. I love shapewear, but have never loved the loud, multi-colored train wrecks often found in men's shape defining underwear. There are plenty of guys who don't mind wearing underwear that looks like the Easter Bunny vomited on them, but I'm not one of those guys. JA is simply sexy and masculine. It's about time! Sorry AC, but you're on your way to the nearest thrift store. I work hard and play harder, and I expect my underwear to keep up with me; whether I'm working out in the gym, backpacking in the Rockies or walking around in Manhattan, there's nothing more important than having underwear that retains its shape, strength/integrity and comfort. Jack Adams delivers across the board. I purchased three underwear types: Core Cycle Trunk; Core Long John; and Core Boxer Brief. While I miss the older 90% cotton/10% eastane fabric used in previous generations of JA underwear (specifically, core trunk), these recent additions perform just as well. Be warned, these ride high on the waist, and they're true to size. Do NOT order a larger size.

Best New Cut

I purchase two pairs of the core cycle trunk and I have to say this is one of the best pairs of underwear I have ever purchased. It is so comfortable and I enjoy the way the brief fits snug and flexible. I am looking forward to buy more.
