Description

The Wiggy's Nautilus with Hood is a +35°F rectangular sleeping bag that does two jobs. Use it alone as a summer bag, or zip a Hunter with Hood core bag inside it to build an FTRSS system for much colder nights.

  • About 40°F colder. Paired with any Hunter with Hood core bag, it drops the combined rating by about 40°F.
  • Holds your core bag in place. A second row of zippers secures the core bag inside.
  • Opens flat. The 118 inch LenZip molded tooth zipper runs down the side and across the bottom, so it spreads out like a comforter.
  • Room to move. A true rectangle at 36 x 92 inches.

It weighs 3.5 lbs and comes with a compression stuff sack and pillow. Choose left or right zipper, and a 118 or 65 inch zipper.

Questions

Nautilus +35°F Rectangular FTRSS Overbag with Hood FAQ

How warm is the Nautilus Overbag?

By itself it's a +35°F summer weight bag. Combined with a Hunter with Hood core bag, it lowers the rating by about 40°F.

Which bags does the Nautilus fit?

It's designed to go over any of the Hunter with Hood (rectangular) core bags. A second row of zippers holds the core bag in place.

Can I zip two of these together?

Yes. Two bags with 118 inch zippers can be mated: unzip both, lay one lining up, put the other on top lining down, and zip them together. With two hooded Hunter bags, one person ends up with the hood under their head and the other has it in front of their face.

What comes with it?

A compression stuff sack and a pillow are included.

What every Wiggy's has in common

One insulation. Everything we make.

Most bags stitch right through their insulation. Every seam is a cold spot. Wiggy's Lamilite is one continuous layer with nothing stitched through it. It breathes, keeps working when it gets damp, and dries fast.

  • For families: no cold spots, so everyone sleeps warm.
  • In the field: keeps insulating when it's wet.
  • For programs: in service for decades, not seasons.
  • At the edge of the map: rated to -60°F.
Why Lamilite works
Most bags: stitched throughEvery seam pinches the insulation flat. That's where the cold gets in.
