Feels great
Love the look and feel of these trunks. I don’t have particularly large thighs — I’m cycle a lot but I’m fairly twiggy — but they are pretty tight on my thighs. It makes me wonder if someone with big thighs would find these too constricting.

Excellent trunk
I recently bought 4 pairs of the aspire trunk. It has been my go to pair of underwear now. I will definitely purchase more for my rotation

I’m very impressed
My name is Isaac, I purchased the aspire trunks, n by far, this has been the best underwear that I have worn in my life, I’m not exaggerating. The day that I wore them for the first time I made my second order right away n got every color available.
