Performance blends last for years with the right routine, and fail fast with the wrong one.
Wash cold and inside out, skip the fabric softener, and let pieces air dry when you can. Softener coats the fibers and kills the stretch and wicking you paid for; high heat is what pills the surface and warps the fit.
Spot-clean between washes rather than laundering every wear. Fewer cycles means less abrasion, and less abrasion is the whole secret to clothes that still look right in year three.
