    They Dissapear

    I'm loving this underwear so far. I've been searching for a while for the perfect pair and sprung when a heft discount was available and I am impressed. I was worried they would be a bit constricting when I first put them on but they really do stretch to fit perfectly without any areas pinching etc.

    I did have some trouble with the shipping, lost package, and they suggested I wait 10 days which felt a bit long before they would send a new set out but they were certainly worth it. My only real complaint is in the available colors. While they do look smart enough I have a preference for ... loud underwear and I wish they would keep some more exiting colors regularly in stock, maybe an orange and a lavender for people of that proclivity.

    I have bought six pairs of underwear and by far they’re my favorite! I would give it five stars if it wasn’t for the price of $53 delivered for 1 pair. I have ordered medium on all pairs and they fit me like a glove, However, the last pair of aspire trunks in medium I got was clearly not a medium, even though it was marked as such. I could not even get them up my quads.

    Completely worth it

    These are the world’s most comfortable activewear underwater. Feels like you’re wearing nothing but amazingly supportive at the same time.

    Repeat customer

    I can't quit this company! Always solid quality, customer service, and quick shipping. Had an issue where one trunk had a small imperfection in the fabric. AWM was quick to send me a replacement. I've been a customer for the last almost 4 years and have never had issues until they wear out from normal use over a couple years.

    The trunks are my favorite cut they offer. short enough to feel almost like a brief, hipster, or cheeky but with more room for the male anatomy over the brief styles. Have to size up in the brief style to keep everything contained.

    Trunks for all day

    I like the trunks better than the briefs. They fit well. I find you need to stretch the legs when you first put them on so they settle more comfortably throughout the day. I like Aspire for everyday.

    Very comfortable, getting them situated is a little difficult but once they are on and situated properly, they do seem to meld and almost vanish, feeling like you aren't wearing underwear at all. But after a reasonably short time they seem to lose the support, if you are just wearing them for a workout or for a few hours, Great, but they don't give the support I would like for an all day pair of underwear.

    As nice as these feel, I do not anticipate purchasing any more, the cost is not even close to justified, $20 a pair might be justified but even that would be debatable, $40+ a pair is ridiculous. After handling them, feeling them, and seeing how they are put together, I would guess the cost is probably less than $1 a pair.

    Pros

    Great feel

    good product

    Cons

    Outrageous price

    After several hours they lose the support they had when you put them on.

    Best briefs ever!

    When I first put these on I was unsure of whether I liked them. I gave myself some time to adjust, and soon realized they are way more comfortable than traditional cotton briefs, and the same was true at the end of the day.!
