Product Details and Uses

The Fox EOS II 2-Person XL Overwrap Skin is a heavy-duty technical accessory engineered to transform your EOS II XL bivvy into a fully insulated twin-skin shelter. Designed specifically to eliminate condensation and dramatically improve thermal retention during freezing autumn and winter sessions, this skin wraps securely over your main bivvy to lock in warm air while creating a valuable covered porch area out front for storing wet boots, bait buckets, and waders.
Crafted from a robust 100% polyester fabric boasting an 8,000mm hydrostatic head rating, the overwrap provides total waterproof protection against torrential downpours and driving winds. Packing down compactly into its own dedicated carry bag, it adds crucial weather resistance and climate control to your setup without taking up excessive space in your vehicle.
Technical Specifications
  • Material Composition: 100% Polyester outer shell
  • Water Resistance: 8,000mm Hydrostatic Head rating
  • Total Weight: 4.7kg
  • Pack Size: 58cm x 17cm x 17cm
  • Compatibility: Engineered specifically to fit the Fox EOS II 2-Person XL Bivvy (330cm x 330cm x 185cm footprint)
  • Included Contents: Overwrap skin and dedicated zipped carry bag
Pro Tip
When pegging out your overwrap skin for long winter campaigns, use the elasticated tension loops to ensure the outer skin is pulled taut and does not touch the inner bivvy walls. Maintaining this physical air gap is essential for creating the insulating thermal barrier that prevents condensation droplets from forming on the inside ceiling.
Ideal Applications & Use Cases
  • Cold-Weather Carp & Specimen Campaigns: Essential for locking in core warmth and stopping frost or condensation buildup during multi-day winter sessions.
  • Extended Porch Storage: Extending the front profile creates a dry, sheltered space outside your main bivvy entrance for bulky gear, wet nets, and muddy footwear.
  • Summer Climate Control: Acts as an extra solar barrier to help keep the interior living space significantly cooler during hot, bright weather.
Frequently Asked Questions
Does this skin fit the standard EOS 2-Person bivvy or only the XL model?
This skin is specifically tailored to fit the larger dimensions and frame profile of the Fox EOS II 2-Person XL Bivvy.
Does the overwrap include its own pegging set and carry bag?
Yes, the skin comes supplied in a compact zipped carry bag (58cm x 17cm x 17cm) and packs down easily when not in use.
How does a twin-skin setup reduce condensation?
By creating a barrier between the cold outside air and the inner bivvy fabric, the skin shifts the dew point outward, preventing internal moisture from condensing on the ceiling above your bedchairs.
