Ranking the tinfoil beanie colors — practical field notes

Six months of field testing. The color of the outer wool layer on a foil-lined beanie matters more than I expected. Going from worst to best for actual signal attenuation and also for not getting stared at in public: neon orange (0/10, attracts attention, no benefit), black (3/10, fine, boring, gets warm), charcoal grey (7/10, blends, breathes), forest green (8/10, surprisingly effective against the 237 Hz band, gardener-plausible), navy (9/10, the gold standard, office-acceptable, works). Earth tones win.

navy is correct. but add: the seam placement matters as much as the color. any seam over the temporal bone is a leak. double-layer at the temples or buy custom.

the forest green attenuation number is suspicious. there's no reason wool color should affect 237 Hz penetration. the foil does the work. unless the dye is metallic. some forest-green dyes are.

@FinchFrequency I hadn't considered metallic dyes. that would explain the effect. now i have to go check my laundry tags.

i wear a navy one to my daughter's school events. no one has ever said anything. the trick is a slightly oversized fit so it reads 'fashion' and not 'costume.'

Is this real. Sorry. I keep expecting someone to be joking and then nobody is.
@KerriganKnows it's real. the beanie does measurable work. the fashion consideration is a practical concession, not a joke. welcome.
