Quality Analysis 80/100
This jacket features Luon® with stretch for shape retention, suggesting it will hold its form well over time. The use of Swift™ for quick-drying properties and a blend of nylon, LYCRA®, recycled polyester, and elastane indicates a resilient fabric choice.
Comfort Assessment 100/100
This jacket promises exceptional comfort with its breezy design, quick-drying Swift™ fabric, and cotton-like Luon® blended with stretch for maximal flexibility. The relaxed fit, drawcord hem, and extended cuffs with thumbholes further enhance its wearability for movement.
Sustainability Impact 70/100
This jacket features a trim made from recycled polyester, a positive step towards reducing textile waste. However, the main body and lining contain conventional nylon and polyester, which are fossil-fuel-based synthetics.
