Compare Big Agnes Benchmark 0° and Echo Park 0° sleeping bags: mummy vs rectangular, packed size vs room. Find your best fit for cold weather camping.
Quick answer
Choose the Benchmark 0° if you prioritize packed size and weight; choose the Echo Park 0° if you want more room to move and a sleep system that keeps you on your pad.
Shape and room: mummy vs rectangular
The Benchmark 0° uses a traditional mummy shape that increases thermal efficiency and provides enough wiggle room to create a cozy space for all types of sleepers. This shape hugs your body to reduce dead air space, which helps retain warmth in cold weather.
The Echo Park 0° is long and wide for those who like a little more room to move around at night, and for campers of a larger stature who want a bag that sleeps just right. If you toss and turn or simply prefer a more spacious feel, the rectangular cut of the Echo Park gives you that freedom.
Packed size and weight: what matters most
When warmth is just as important as packed size and weight, the Benchmark 0° shines. Its high-loft synthetic insulation compresses well, making it a solid choice for backpacking or any trip where every ounce and cubic inch counts.
The Echo Park 0° is ideal for car camping or an overnight on your friend’s floor. It’s built for luxurious sleep rather than minimal pack weight, so if you’re not carrying it far, the extra room is worth the bulk.
Sleep system compatibility
The Echo Park 0° features the Big Agnes PadLok™ Sleep System, which keeps you on your pad all night. If you’re a restless sleeper who tends to roll off your pad, this system is a practical advantage.
The Benchmark 0° doesn’t list a pad attachment system in its specs. If pad security is a priority, you may need to use a separate pad sleeve or accept that the mummy shape naturally keeps you more contained.
Trade-offs at a glance
- Room vs. efficiency: Echo Park 0° gives you more space to move, but the Benchmark 0°’s mummy shape is more thermally efficient. If you sleep cold, the mummy shape may keep you warmer with less insulation.
- Pack size vs. comfort: Benchmark 0° packs smaller and lighter, while Echo Park 0° is bulkier but more luxurious for car camping. Think about how far you’ll carry the bag before choosing.
- Pad security: Echo Park 0° has a built-in PadLok™ system; Benchmark 0° does not, so you may need extra gear to stay on your pad. If you’re a side sleeper who moves a lot, the pad lock is a real benefit.
