Big Agnes Copper Spur UL4 Footprint tent floor

Product description

Protective Groundsheet for UL4 – extends the tent's lifespan and enables ultralight Fast Fly setup

The Big Agnes Copper Spur UL4 Footprint protects the tent floor from wear, moisture, and dirt – particularly important when hiking on rocky or wet ground. The footprint is tailored for all UL4 models with TipLok™ Tent Buckles and also works for Fast Fly mode, where you set up only the outer tent with the footprint, poles, and pegs. Made from durable 30D HyperBead™ ripstop nylon with 1500 mm waterproofing, completely without added PFAS. Seams are taped with solvent-free polyurethane for waterproofing without PVC or VOC.

Features

• Protects tent bottom: Prevents wear, moisture, and dirt – perfect for challenging terrains.

• Compatible with UL4: Fits models from 2020 and onwards with TipLok™ Tent Buckles.
• PFAS-free fabric: 30D ripstop nylon with silicone and PU treatment – durable and environmentally friendly.
