1. A multifilament yarn comprising a number n of filaments, wherein the filaments are obtained by spinning an ultra-high molecular weight polyethylene (UHMWPE), said yarn having a tenacity (Ten) as expressed in cN/dtex according to Formula 1:
Ten(cN/dtex)=f×n−0.05×dpf−0.15  (Formula 1)
wherein Ten is at least 39 cN/dtex, n is at least 100, f is a factor of at least 58 [ 62.0 ] and dpf is the dtex per filament.
