Ventile
A tightly woven long-staple cotton fabric originally developed for RAF pilots in WWII. Naturally waterproof when wet — fibers swell to close gaps. Premium heritage fabric for outerwear.

What this score doesn't measure
This is a material rating, not a verdict on any specific garment made from ventile. The axes above are research-backed averages for the fiber itself.
- ×Construction. Yarn staple length, weave / knit structure, stitch count, finishing. Identical fiber, very different garments.
- ×Fabric weight (GSM). A 140 GSM tee and a 220 GSM tee made of the same ventile feel and last very differently.
- ×Dye + finishing chemicals. Beyond the three we flag (PFAS, formaldehyde, antimony), dozens of textile finishes aren't modelled.

+14 vs Ventile · 92/100
BiodegradableThe rarest and most expensive animal fiber in the world, from the vicuña of the Andes. Finer than cashmere, incredibly soft, warm, and lightweight. A single coat yields only 250g of usable fiber every 2-3 years.
+8 vs Ventile · 86/100
BiodegradableUltra-fine wool from Merino sheep. Softer and less itchy than regular wool, with excellent temperature regulation and moisture management.
+4 vs Ventile · 82/100
BiodegradableExtra-long-staple cotton historically grown in the West Indies (Barbados, Jamaica) and Sea Islands of Georgia/South Carolina. Among the rarest commercial fibers on earth — staple length up to 2.5", silky hand feel, intense color saturation when dyed. Used in heritage luxury shirting and bespoke menswear.
Care Guide
Special Notes
• Densely woven cotton — naturally water-resistant
• Re-proof with wax or DWR spray after washing
Additional Care Tips
- • Machine wash warm (40°C/105°F) on gentle cycle with mild detergent
- • Tumble dry on low heat — heat reactivates the water-resistant properties
- • Iron on medium heat to restore fabric tightness and water resistance
- • Do not use fabric softeners — they impair waterproofing
- • Re-proof with wax or DWR treatment if water resistance diminishes
- • Hang to store — avoid compressing for long periods
