800-fill down stays compressible for 15+ years. Cheap jackets lose loft in one season.
Why Not Just Buy the Cheap One?
Low-grade synthetic and down insulation from fast-fashion brands compacts and loses thermal efficiency in 12 months. Patagonia's 800-fill-power down resists matting, their repair service keeps it functional for decades, and the nylon shell doesn't degrade. You're not buying insulation; you're buying a system.
The Buy-Once Math
Cheap winter jackets cost $60-100 but become useless after one season of compression and water exposure. You buy a new one every year—that's $700-1,200 in a decade. One Patagonia jacket at $319 lasts 15+ years, and they'll repair rips for cheap. Do you want 10 jackets or 1 that works?
