ATEPA BULWARK 300 3-in-1 Convertible Sleeping Bag | 300g 650FP Down Blend for Backpacking & Camping

One Sleep System, Three Ways to Use It. Your Ultimate Bag for Every Season.

Introducing the ATEPA BULWARK 300 – the sleeping bag that adapts to your adventure. Unlike rigid mummy bags, our innovative 3-in-1 system gives you the freedom to use it as a standalone top quilt, attach it to your favorite sleeping pad, or zip it up as a traditional sleeping bag. Filled with a 300g blend of 650+ fill power down and recycled cotton, this versatile bag is built for backpackers, campers, and outdoor enthusiasts who demand comfort, adaptability, and quality in any season.

Why the 3-in-1 BULWARK 300 is Your Smartest Gear Choice:

✅ UNIVERSAL 3-IN-1 CONVERTIBLE DESIGN
Stop buying separate gear for different trips. The BULWARK 300 is three systems in one:

1. A Top Quilt: Detach and use the top as a breathable, lightweight blanket for warm nights or van camping.

2. A Pad Cover: Securely attach the integrated sleeve to your existing inflatable pad (standard 20"-25" width) for a stable, integrated sleep system.

3. A Full Sleeping Bag: Zip it up completely for traditional, cozy protection on cooler nights.

✅ PERFECTLY BALANCED FOR 3-SEASON COMFORT
Engineered with a 51% down / 49% recycled cotton blend, this bag offers the perfect balance of loft, moisture resistance, and eco-conscious materials. It’s comfort-rated to 53.6°F (12°C) with a lower limit of 44.6°F (7°C), making it your go-to for spring, summer, and fall adventures where nights can be unpredictable.

✅ DESIGNED FOR REAL-WORLD COMFORT & DURABILITY

• Expanded 3D Foot Box: No more cramped toes. Our foot box design gives your feet room to move, improving circulation and overnight comfort.

• Stays-In-Place Baffles: Cross-quilting and 3D baffle construction prevent down from shifting, ensuring even warmth distribution all night long.

• Full-Zip Versatility: Unzip it completely for use as a blanket, or zip it up with the draft flap and adjustable hood for a snug, windproof seal.

• Eco-Tough Materials: Made with a 20D 400T recycled nylon shell (water-repellent & down-proof) that’s durable, easy to clean, and kinder to the planet.
