Snugpak Basecamp Ops Nautilus Sleeping Bag

Isofibre® Synthetic Fill Sleeping Bag With Two-Way Zip and Quilt Conversion

The Snugpak Nautilus sleeping bag brings the performance standards of Snugpak's full tactical lineup into an approachable, versatile package built for campers, outdoor enthusiasts, and anyone needing a reliable three-season bag. Part of the Basecamp Range, the Nautilus uses Snugpak's Isofibre® synthetic fill, a highly siliconised fibre construction that delivers substantial warmth with a soft hand feel and a longer usable lifespan than traditional synthetic fills. Rated to a comfort temperature of 37°F (3°C) and a lower limit of 28°F (-2°C), the Nautilus packs down to 8 x 9 inches and weighs 49oz. The square foot version opens flat into a full quilt or blanket for warmer-weather use, and left and right hand zip variants connect together to form an oversized two-person bag.

Features

• Snugpak's Isofibre® fill uses highly siliconised synthetic fibres that provide greater warmth-to-weight performance and a softer feel than traditional synthetic fills, with a longer service life through repeated wash and compression cycles.
• The square foot version opens fully flat to function as a standalone quilt or blanket, giving you a second mode of use in warmer weather or when sleeping in a shelter with existing insulation.
• Left hand and right hand zip variants are fully compatible and zip together to create a large two-person sleeping bag, making the Nautilus a practical choice for couples or shared cold-weather shelter setups.
• The anti-snag two-way zipper with integrated zip baffle lets you vent from either end of the bag for temperature regulation without snagging on inner lining material during low-light entry and exit.
• The draft collar and Snugfit hood work together to seal warmth around your neck and head, eliminating the main cold-entry points that undermine lower-end sleeping bags as temperatures drop.
• Hanging dry tabs on the interior allow you to hang the Nautilus for air drying or long-term storage without compressing the fill, preserving loft over the life of the bag.
• The reinforced foot lining resists the wear and abrasion that accumulates at the foot box through regular field use and compression storage.
• The included compression stuff sack packs the Nautilus down to 8 x 9 inches for ruck or kit bag carry.
