Description

The Wiggy's Nautilus FTRSS Overbag is a +35°F rectangular summer sleeping bag on its own. Zip it over any Hunter (rectangular) core bag and it lowers the combined rating by about 40°F.

Two bags in one. Use it alone in summer or as the overbag in the FTRSS.
Holds your core bag in place. A second row of zippers secures the core bag inside.
Opens flat. The standard 118 inch LenZip molded tooth zipper runs down the side and across the bottom, so it spreads out like a comforter.
Mate two bags. Two bags with 118 inch zippers zip together for couples or for sharing body heat in an emergency.

Size: 36 x 92 inches. Weight: 3.5 lbs. Compression stuff sack and pillow included. Choose left or right zipper and a 118 or 65 inch zipper. Interior color will vary.

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.
