    • Comfortable, Durable, and Perfect Fit Underwear
Size: Large Color: 3 Black
I was genuinely impressed with the quality of these underwear. The fabric feels soft against the skin and provides excellent breathability, which made them comfortable to wear throughout the entire day. The fit was perfect — not too tight, not too loose — and the waistband sat naturally without digging into the skin. Even after wearing them for a long time, they never felt restrictive or uncomfortable. The elastic held up well and didn’t stretch out or lose its shape over time. I also appreciated that the material allowed my skin to breathe, which made a noticeable difference during warmer days. Overall, these are well-made, comfortable, and long-lasting underwear that I would definitely purchase again. ... show more

    • Favorite of 3 brands tried! Between sizes? Order UP
Size: Medium Color: 3 Black
Purchased these as part of my teen's annual back to school wardrobe refresh. He asked for an upgrade from basic 12 packs of "kid's underwear". In support of his continuing efforts to look like a "grown *ss man", we purchased from 3 different brands: Shiniquo, Bonds, and Calvin Klein. All 3 brands delivered great fit & comfort, but these CK briefs are his favorite overall. Per the sizing chart my son is right between sizes so we took a chance and ordered UP. The larger size fit him perfectly. If you're buying these for a still growing kid, you might want to do the same. The material is very lightweight but not sheer, and has a slightly slippery texture like a sweat-wicking gym shirt. Throughout the hot summer days these keep him the coolest. He likes the leg length and the smoothness of the seams & waistband. For their thinness these seem really durable. Great value, especially on sale. ... show more

    • ultimate blend of style and comfort!!
Size: X-Large Color: 3 Black
The Calvin Klein Men's Micro Stretch 7-pack Boxer Briefs are like wearing a cloud! The superior comfort is unmatched, making them my go-to choice for the last two years. The elasticity is amazing, allowing for a perfect fit that moves with you throughout the day. These boxer briefs provide the support you need without sacrificing comfort, and the variety in the pack is a nice bonus. If you’re looking for the ultimate blend of style and comfort, these are definitely worth it! ... show more

    • Great quality – just pay attention to sizing
Size: Small Color: 3 Black
I’m really happy with these Calvin Klein underwear! The fabric feels soft and high-quality, the fit is flattering, and they’re super comfortable throughout the day. You can definitely tell it’s a premium product with great attention to detail. One small note: the sizing runs a bit small. I usually wear a size Small, but in this case, Medium would have fit better. If you’re between sizes, I recommend going one size up. Overall, excellent product – I’ll definitely be ordering again! ... show more

    • Iconic men's boxer briefs!
Size: X-Large Color: 3 Black
Comfortable, high quality, long lasting, right length that doesn't ride up. Sizing runs small--I wear between a 34 and 36 inch trousers, but always buy X-Large Calvins. Have worn Calvin underwear since they were cotton and am very happy with their comfort and durability. Often on sale at Amazon.com.

    • Never thought I'd be brand loyal
Size: Medium Color: 3 Black
However, I have found that my CK's last an extral long time. The waistband does not stretch out even after 10+ years of having them- Incredible! I'm weird and I went through a major underwear search years ago. I tried everything but I'd have to wait long enough to see how they would perform over time. These beat out my addidias and various other performance briefs. This particular brief is a 10/10 for working out. They hold you in place and wick away moisture. These were on sale when I bought them, but if I find another sale I'll be getting some more. Buy them without any regrets. You'll love them. ... show more
