Calvin Klein Men's Underwear Air FX Micro Low Rise Trunks

Excellent product, it is breathable and really helps if you sweat easily (or if your butt sweats a lot)! Comfortable and looks great too! The size chart is accurate so do follow it! But if you like a looser fit like i do, you could still wear a M size even if you're a waist size 29 or 30.

Best Calvin Klein undies! My bf loves these! They fit great and still breathe well. He is very active and says these have been great for that! They also are very durable. He has had a few previous pairs for a few years already without any ripping or over stretching. He hopes they continue to make this line!

My favorite boxer-briefs of all time are UA Boxerjocks. However, wearing the exact same style for years and years gets tiring. I initially thought I wanted briefs, so found my way to the Air FX briefs, which are great. They are the best briefs ever and very supportive. However, in this day and age I feel pretty self-conscious wearing briefs. So, I made a compromise and went to the trunk version. It rides up to something just like a brief but still decidedly boxer-brief. It has most of the comfort, support, and looks of the Air FX brief with just enough modesty to walk through the house without feeling embarrassed or singling yourself out as that guy who wears briefs. Makes me feel right both physically and socially.

These are comfortable, non-binding, not heat retaining underwear. Has the right amount of elastane to give without drooping. Ordered one size larger than I usually wear as they do fit low on the waist. Leg length is right for me. Any longer and the legs would pull down.

Very comfortable. Lightweight and moisture-wicking. Look good too. Wore all day without tugging and adjusting. I have a 34 waist and the large fit perfectly. Bought another pair but only one as they are a little pricey. Can't comment on quality yet but seem well constructed.

These are a fantastic version of an already great line of Calvin Klein underwear. They fit like the Pro Stretch Trunks, but with more air holes. These are a nice and light, great for summer wear!

These were great for the first year I had them, but after being washed/worn a few times the fabric starts to get pills that snag on the inside of your jeans. It's the strangest thing. You can literally feel them being ripped off the underwear by your jeans as you walk. They fit great and actually breathe. The wife likes 'em so take that for what it's worth.

They don't ride up no matter what level of activity you do (running, squats, hiking) and are incredibly comfortable.

El color esta increíble se ajusta muy bien y la tela es excelente

Excelente opción en underwear

Increíble calidad y textura de la tela. Cómodos y frescos para usar en época de calor. Llegaron en su empaque original.

Muy buena calidad, tamaño, ergonomia, el precio en su momento fue muy bueno ahorita ya esta muy caro, si volvería a comprar al mismo precio.

Best underwear out there.
