I have been wearing Calvin Klein for a long time and decided to try a bunch of new underwear. This was the only cotton pair and I like them the second least. They don't have the best fit and aren't as comfy as the others. However, they were by far the cheapest, so for the price I will still give them 4 stars. Quick comparisons to the other brands are below, ranked by my personal preference.
1. Lululemon Always in Motion Boxer 5 Inch - 5 Stars: Easily the most comfortable, but pretty pricey. The only pair that doesn't ride when moving around.
2. Under Armour Men's Tech 6-inch Boxerjock 2-Pack - 4.5 Stars: Not quite as comfortable as Lululemon, but still pretty comfortable and more affordable. Great at absorbing moisture but ride up your leg a bit sometimes.
3. Calvin Klein - 4-5 Stars: I actually have a ton of these and don't remember the exact ones. Some of them fit decently well, and some not so much. On average they are pretty decent though
4. ExOfficio Men's Give-n-go Boxer Brief - 3.5 Stars: These are... fine. They are middle of the road in comfort and good at absorbing moisture. But for the price there are just way better options.
5. Pair of Thieves Super Fit Underwear for Men Pack - 2 & 3 Pack Boxer Briefs - AMZ Exclusive - 3.5 Stars: These are weird. Super comfy when dry, but terrible moisture absorption. When even slightly wet they are super uncomfortable. Definitely don't plan to sweat in these.
6. Pair of Thieves Cotton Boxer Briefs for Men Pack (4 Pack) - 4 Stars: Not as comfortable as all of the non-cotton options, but a decent value.
7. Smartwool Boxer Brief - 1 Star: Complete and utter garbage. Overpriced, not very comfortable, not any better at wicking moisture away than all of the similar priced options.
