Can I use this on a hammock?
✅ Yes – but only on suitable materials.
Safe for:
- Canvas and polycotton hammocks: Cotton Proof can help these absorb less moisture and dry faster—useful in humid or wet conditions.
- Treated canvas covers, tarps, or cotton gear bags can also benefit from a waterproofing boost.
⚠️ Not for synthetic hammocks (ripstop nylon, parachute silk, polyester). For those materials, use Nikwax Tent & Gear SolarProof instead.
💡 Always test on a small area first, especially with dyed cotton, to check for any changes in appearance or texture.
