Grand Trunk 360 ThermaQuilt 3-in-1 Hammock Underquilt, Blanket & Sleeping Bag – Blue/Navy

Meet the Grand Trunk 360 ThermaQuilt, a versatile outdoor companion that adapts to hammock setups, cool nights, and varied terrains. In a timeless blue and navy palette, this 3-in-1 design blends compact practicality with real-world comfort, so you can tailor your layer system to the moment—without juggling multiple pieces of gear. From quiet forest camps to riverside strolls, the ThermaQuilt aims to stay adaptable, cozy, and easy to manage as the day evolves.

All-in-One Comfort for Any Setup

The 360 ThermaQuilt is built to flex between three useful roles: a hammock underquilt or overquilt, a sleeping bag, or a lightweight blanket. This one-piece approach helps you shift between lounging and sleeping without swapping gear, which can simplify packing and reduce bulk.

• 3-in-1 design supports hammock comfort, sleeping, or blanket use for varied conditions.
• Warmth and dryness are supported by synthetic insulation designed to perform in cooler conditions.
• Cord tunnel with cinch lock helps preserve warmth and minimize drafts for a snug fit.

Warmth, Insulation and Easy Adjustments

With 140 GSM synthetic insulation, the ThermaQuilt aims to provide steady warmth when temperatures dip. The thoughtful cord cinch system helps you customize the fit, so you can focus on the moment—whether you’re listening to a crackling campfire or watching a late-night meteor shower.

• Insulation targets warmth in cool conditions without adding excessive weight.
• Cinch-tied cords help block drafts while letting you tune the fit to your hammock or sleeping position.

Designed to travel light, the ThermaQuilt weighs 29 oz (822 g) and packs down to a compact footprint. When unfolded, it offers generous blanket and sleeping bag dimensions, while still folding down small enough for backpack journeys.

• Weight: 29 oz (822 g) for easy backpacking or car camping
• Pack size: 7.5” x 15” for versatile stowaway handling

Designed for Outdoor Enthusiasts

Designed in Salt Lake City, Utah, the ThermaQuilt brings a local craftsmanship mindset to outdoor comfort. Its blue/navy colorway suits a range of environments, from forest trails to lakeside camps, while maintaining a focus on practical performance and easy care. Whether you’re pairing it with a hammock or laying it out on the ground, this 360-degree option aims to adapt as your plans evolve.

In real-world use, you might start the evening with the underquilt snug against a chilly hammock, switch to a relaxed blanket during a campfire, then seal the night with a compact sleeping bag setup as sleep approaches. The 360 ThermaQuilt is designed to be flexible, so you can explore multiple comfort layers without carrying separate pieces of gear.

Explore the possibilities with confidence, knowing you have a single, adaptable layer that can respond to changing conditions while staying true to a lightweight, travel-ready footprint.
