Trainer Trunk

Usually ships within 24 - 36 hours of receipt of order, excluding weekends

Product Description

Named one of "Men's Health" Top 10 Athletic Underwear. The Jack Adams Trainer Trunk combines the athletic support of a jockstrap with the comfort and coverage of traditional underwear. It's ideal for playing sports and other strenuous activities, because of the anatomical support provided by its full front pouch. This trunk also features a fully functional fly. Plus, the body hugging cut keeps it from riding up the thigh while being active. With super soft fabric, this comfortable trunk can easily be worn all day long too. Made from 90% Cotton and 10% Elastane.

  1. camo cool

    Posted by Unknown on 26th May 2017

    Fantastic fit comfortable and fashionable. Would order more.

  2. Nice Fit & Fabric

    Posted by JB on 26th Apr 2017

    These are comfortable and are made of nice fabric. I like the fit of the legs, and they stay in place.

    The camo version has a flannel-like feel. I liked them enough to get one in each color. I thought at first they might be good as work-out shorts, but I haven't tried that in public yet.

    I don't have to tug and rearrange things in the pouch too much. There is a bit of a push-up effect to the cut of the pouch that I wasn't expecting, so it takes a little getting used to, and it sometimes feels a little crowded in there, but it's still comfortable.

  7. game changer

    Posted by Unknown on 26th Jan 2017

    I've been looking for comfortable running underwear for 6 months. Tried it all and everything hurt until I found these. I can run as much as I want and be totally comfortable. Highly recommend.

  8. Keeps everything in place!

    Posted by Bob F on 10th Nov 2014

    I primarly wear these for yoga and/or working out, particulalrly abb work.. Keeps everything in place. May be a bit heavy for everyday underwear but they are awesome when I use them.

  9. Great comfort, warm not suitable to workout in

    Posted by Unknown on 18th May 2014

    Very comfortable, enough room for all the bits and pieces. But found the fabric to be thicker than ideal. Held in heat and got sweatier than expected. Like them, but will wear only for sleeping in. Not for moving around.

  10. Good stuff.

    Posted by Unknown on 28th Apr 2014

    Comfortable, and looks great. I also love the horizontal fly. I will buy this again!
