I’ve had the boxes for about 2 to 3 weeks worn them a few times and it seems the fit is just not there :(
Very comfortable, doesn’t ride up
Great fit. Super comfortable and breathable.
This mid the 2nd pair from your line of men’s underwear. I am a muscular guy so I have a pair of XL and they are loose on the waist and good on the legs so I tried a large. That pair is good on the waist but right on the legs so I have to pull them up a little. The quality is good and they are comfortable but if your a muscular guy you get stuck in between sizes. That unfortunately is my dilemma and for $50 a pair that’s not a great fit.
I received the Tani -JAirfit in navy, boxer. Wow! I can't believe how great they fit. The waistband is what surprised me, it is soft, comfortable to wear. The material is fantastic!
I would recommend these to everyone.
Doesn't fit well. Baggy in the waist and right across the butt. Quality doesn't seem great. I would not buy another pair even at half price.
Airfit boxer brief, only wore once, nice fabric, legs loose, not form fitting
The airfit boxer briefs are nice and lite. But the first day I wore them, after about 8 hours the legs were losing their shape and not fitting as snugly as at the start of the day. My impression from the website was that the quality was so high that I wouldn't have these types of problems. Also, the boxer briefs are more like trunks that boxer briers.

This underwear is amazing that I don’t feel anything.

The quality is great 10/10. Going to buy more.
Large was too big for me!
love the products. Comfort level for almost all my purchases has been great, nearly perfect. wish there were more selections in style and color for some items. Will continue to purchase.
Great fit! Great for the gym!
In love! I recommend the underwear!
I am so happy with my items it’s is very high quality! & the feel of the underwear is more than what I expected and more !
I recommend !
Love love love !
I’ve ordered a couple different pairs and I feel I’m in between a medium and a large and that may have to do with me having large legs. Extremely comfortable and I look forward to ordering my next pair.
The airfiet boxer briefs are just okay for me. The mesh fabric is very light and comfortable, as is the waist band. But the length is shorter than I prefer, and I find they seem to stretch out of shape a bit. For workouts I prefer the Move boxer briefs.
Great for summer times
