Collection: ULTRAGRID & VENOM ECO

UltraGrid™ & Venom™ Eco Collection

Ultralight. Eco-Friendly. Surprisingly Tough.

When weight matters and performance counts, these two technical fabrics rise to the occasion. The UltraGrid™ & Venom™ Eco Collection brings together the best of both worlds: high-performance materials built for fastpacking, hiking, and travel—with a strong focus on sustainability.

🏔️ UltraGrid™ by Challenge Sailcloth

  • Made from 100% recycled nylon yarns, including high-tenacity ripstop

  • Weighs in at just 3.5 oz/yd² — perfect for ultralight setups

  • Double ripstop construction for added tear resistance

  • Finished with a C6 DWR coating for weather resistance

This fabric punches way above its weight class. Ideal for ounce-counting adventurers and organized travelers who need durability without the bulk.

🌿 Venom™ ECO

  • Crafted from ultralight, recycled 210D nylon

  • PFAS-free, PFC-free, and proudly eco-conscious

  • Matte finish and slightly firmer hand feel than UltraGrid™

  • Naturally water- and abrasion-resistant

Venom™ Eco blends a technical feel with clean aesthetics and a low environmental impact. It’s a bit more structured than UltraGrid™, making it ideal for pouches that need to hold their shape.


Whether you're dialing in your backpacking loadout or color-coding your travel kit, this collection lets you pack smart, travel light, and leave a smaller footprint—without compromising on quality.

Ultralight. Earth-friendly. Ready for wherever you roam.
