Key Features
- Deluxe Camping Comfort: The Echo Park Series is built long and wide to accommodate campers of larger stature or those who enjoy ample movement during sleep. Its spacious design makes it perfect for car camping, backyard lounging, or even an overnight at a friend’s place.
- Big Agnes Padlok Integration: Combines seamlessly with your sleeping pad using the Cinch Pad Sleeve, which securely attaches the bag to pads sized 25–30” wide by 78” long. This creates a stable, quilt-like bed that reduces air gaps and improves warmth retention.
- Cozy Quilt-Style Top: Features a quilted upper section similar to a comforter, allowing easy shoulder coverage via corner hand pockets. The design promotes natural body heat circulation while maintaining insulation efficiency.
- Enhanced Draft Protection: Includes an oversized draft collar and zippered draft tube that seal out cold air, maximizing thermal efficiency without compromising access to zippers.
- Comfortable Free Range Hood: Offers full coverage with the freedom to lift your head comfortably, reducing neck strain and improving airflow when needed.
- Pillow Barn System: The pad sleeve includes a built-in pillow barn that keeps your pillow secure all night while allowing natural head movement, eliminating the need for additional straps or adjustments.
- Double Zipper Design: Allows entry from either side and enables easy ventilation on warmer nights. Bags within the Park Series also mate together easily, making shared sleeping simple.
- Internal Storage & Packing Options: Comes with an internal mesh stash pocket for phones, keys, or small items, plus two storage sacks—a mesh sack for long-term storage and a smaller stuff sack for active use. For optimal compression, pair with a Big Agnes Compression Stuff Sack or Superlight Girdle (sold separately).
- Sustainable Insulation: Filled with FireLine Max Eco insulation made from 100% post-consumer recycled polyester. It blends hollow and solid fibers to provide excellent loft, warmth, and compressibility without added PFAS chemicals.
- Quiet, Soft Lining: The interior uses a cotton/polyester blend that feels soft against skin and produces minimal noise, enhancing overall coziness during sleep.

Benefits & Use Cases
The Big Agnes Echo Park 40 excels in environments where comfort and warmth are priorities, such as base camps, tailgating setups, or extended weekend trips. Its roomy shape suits campers seeking more freedom than traditional mummy bags allow, making it ideal for side sleepers or those who toss and turn frequently. The integration with sleeping pads via Padlok technology ensures stability and eliminates shifting, which is especially beneficial during windy nights. The quilt top allows for greater flexibility compared to fully enclosed designs, enabling users to drape the bag lower if they wish, while still retaining insulation around the core. Double zippers make it user-friendly for couples, allowing individual temperature control and easier access when sharing. The inclusion of hand pockets and a pillow barn adds daily convenience, mimicking familiar home comforts. Overall, this sleeping bag strikes a balance between performance and indulgence, catering to those who value restorative sleep over extreme weight savings.
