Let me start by saying I've officially retired all my old underwear after trying Calvin Klein's Cotton Stretch Boxer Briefs. The first time I put them on, it felt like upgrading from economy to first class - that same 'why didn't I do this sooner?' moment.

The cotton-spandex blend is where the magic happens. Unlike cheaper alternatives that either strangle your thighs or sag like a hammock, these move with you perfectly. I've worn them through everything - from marathon workdays to actual gym marathons - and never once had that annoying mid-stride adjustment moment we all know too well.

What surprised me most was how they solved the Goldilocks problem of underwear: not too tight, not too loose. The contoured pouch gives just enough support without feeling restrictive, while the leg openings stay put without digging in. After about 20 washes (I've been counting), they still look and feel new - no stretched-out waistbands or faded colors.

The moisture-wicking actually works. I used to think that was just marketing speak until I wore these on a disgustingly humid day and realized...I wasn't miserable. That alone makes them worth every penny.

Pro tip: Hang dry them as suggested. I learned this the hard way after shrinking one pair (totally my fault). But even that pair still fits better than most of my old underwear at their best.

If you're debating whether designer underwear is worth it, take it from someone who was skeptical too - these will change your mind within one wear. My only regret? Not buying more packs sooner.
