Tim’s Recommendation: 

I’m not a fan of trunks in general, but this pair surprised me. It gave me ample support and felt more like a brief than a trunk. If you’re looking to try something new or need more classics in your drawer, this pair is for you.

First, it’s a given that I am not a big trunk/boxer brief fan. But I always review a pair with an open mind. This is my second pair of Butch underwear, and after the Brief, I was looking forward to this review. It was going to be interesting to see how they made trunks. I didn’t notice a built-in pouch, so I was hoping for the best. 

I wore these on a busy day when I would be moving around a lot and out and about. The heat in GA has been 90’s and HUMID. This was an extra complication for this review. I hoped they held up like the briefs and didn’t get hot, bunch, or be uncomfy.

As the day went on and I was running errands and working. I forgot I was wearing trunks, which is rare for me when I sport them. It’s usually a leg ride up, or it bunches up, or the pouch isn’t holding up. Even without a built-in pouch, this pair gave me support, and I didn’t have to continually adjust or wish I was wearing a brief.

Sizing is always an issue when you are a bigger guy. Not with Butch, they have sizing from Small to XXX-Large. I got an XL, and it fit perfectly! They are based out of Australia and have pretty standard sizing. If you are on the larger side, check out the size guide for the right size. I don’t think you will go wrong by following their direction. 

This pair was just like the brief. It was made with a fantastic waistband that never dug into me or made me feel the pair wasn’t made for me. The fabric feels terrific, as well. I’m still surprised I liked this pair as much as I did. It’s very rare. I wear trunks and enjoy them. As the last podcast, I mentioned a few I liked, but there aren’t many

If you are a bigger guy give Butch underwear a try, you won’t be disappointed.
