A little expensive. But a good product and selle.

Great Comfort, Great Value — A Staple in My Drawer!
Size: Medium
Color: 3 Black, 2 Grey Heather, 2 White
I’m really pleased with the Calvin Klein Men’s Cotton Classics 7-Pack Trunk. The cotton fabric is soft and breathable, so these feel comfortable all day long — whether I’m lounging at home or out running errands. The fit is just right: snug enough to offer support, but not too tight or restrictive. The quality is exactly what you expect from Calvin Klein — the stitching is solid, and they’ve held up well after multiple washes with no fading or shrinking. Getting seven pairs in one pack is such a value: it’s made it super easy to stock up without worrying about frequent laundry days. If you want classic, everyday underwear that’s comfortable, reliable, and easy to maintain — this 7-pack is a smart buy. Highly recommend!

The Most Honest Review Possible
Size: Large
Color: 7 Black
Where do I start with a product of dismal quality? First of all, I ordered a Medium originally because it, according to size chart, should have fit me. Once they arrived they were far too small. Not the biggest deal. I returned them and ordered the Large size. They were still tight but I gave them a shot. After washing the underwear on a normal wash cycle and subsequent warm dryer cycle, like any normal human would do, the underwear became so small and tight it felt like a Ric Flair was twisting the ol'family jewels to win the world heavyweight champion title. Do not buy these. They are not worth any amount of money because they cannot be washed and dried like normal clothes without completely changing the size and fit. Spend the money, buy Lululemon or Saxx underwear. If you enjoy pain and suffering like the kind you experience from a latex-clad dominatrix in a cheap motel room, these underwear are for you.

Fit isn't best but great value
Size: Small
Color: 3 Blue Depths, 2 Boardwalk Blue, 2 Water...
The fit wasn't what I was looking for, the crotch is a little looser than I expected, but love the price for all of these and the brand.

Best Value for these Great Trunks
Size: Large
Color: 7 Black
I've been wearing this product for over 20 years. They look great and feel good when I wear them. To me they are the perfect combination of comfort and support. And in my experience, the brand name on the elastic band elicits a superior response from other persons privy to seeing them than Hanes or Fruit of the Loom. Nothing lasts forever, so they will begin to fray and wear out after a large number of weekly washes, which for me is 3-5 years. Buying them at the retail store is very expensive, so I always wait for a sale. But this bundle is the best value I've ever seen, so of course I bought some.

I expected a little better from Calvin Klein honestly and for the price! If not for the black Friday special I'd return. No way they are worth full price. So yeah, I kept them and wear them but they're are average! Didn't know Calvin Klein was average now!

Exceptional qualty
Size: Medium
Color: 7 White
Very good quality and cut, especially if you're looking for the shorter leg length and 100% cotton, which is getting harder and harder to find.
