Polygiene keeps the shorts fresh for longer","entries":{"in_fabric_integration":"Unlike topical sprays that sit on the surface, Polygiene is embedded during the fabric's finishing stage with no extra water or energy, creating a permanent bond that won't wash out, peel, or lose effectiveness over the entire lifespan of the shorts.","multi_day_stink_test_proof":"Independent field tests of Polygiene-treated apparel have shown it can go 20 hours of sweaty wear over two weeks without developing any odor, and survive 5+ hours of running and indoor cycling with only a faint smell detectable when pressing your nose directly into the fabric—performance that suggests these shorts can handle a week of workouts or a long weekend trip between washes.","wash_less_lifecycle_savings":"Polygiene's published lifecycle analysis indicates that skipping every other wash trims a garment's environmental footprint by about one-third, which translates to roughly 3,800 litres of water and 51 kWh of energy saved per year per consumer—so wearing these shorts twice between washes directly cuts resource use.","skin_safety_and_certifications":"Polygiene StayFresh holds bluesign® approval and Oeko-Tex Eco Passport certification, and independent sensitivity tests confirm it's skin-safe for prolonged wear and doesn't interact with your body's natural bacteria—only the odor-causing microbes on the textile.","endorsement_by_performance_brands":"The same Polygiene technology is used by elite outdoor brands like Patagonia, Arc'teryx, The North Face, and Montane, indicating that the odor control in these I.FIV5 shorts is trusted for high-output, multi-day mountain and trail activities.","eco_synergy_with_recycled_polyester":"Pairing Polygiene with the short's recycled polyester fabric creates a dual-benefit sustainability profile: the recycled construction lowers virgin plastic demand, while the need to wash less often can reduce the garment's lifetime environmental impact by roughly a third, according to Polygiene's life cycle data.","silver_chloride_anti_odor_mechanism":"Polygiene StayFresh relies on silver chloride—a naturally occurring silver salt—whose ions block bacterial growth by disrupting cell walls, DNA replication, and enzyme function, so odor-causing microbes can't multiply on the fabric no matter how much you sweat."},"entry_quotes":{"in_fabric_integration":[{"url":"https://polygiene.com/stayfresh/","quote":"This advanced antibacterial textile solution is integrated into the fabric, so freshness is built-in for the lifetime of the garment.
