I love my Buff heavyweight merino beanie. Classic cut that covers the ears properly, very supple and soft material, much nicer than any acrylic knit. Mine is 2 years old, which isn’t yet a lifetime of course, anyway it has no holes, no ripped up stitches, not even much pilling. I’m not overly gentle to it too, and often wear it under the parka hood, stuff it in the pocket when entering stores, wash it with my usual detergent (nothing extra delicate or wool-specific). Colors match their neck gaiters, and the logo on the heavyweight version isn’t too prominent. I also have it in lightweight merino, which is fine for mild weather or sports, but the quality of the heavyweight seems better.
