Compare the Benchmark 35 and Echo Park 35 sleeping bags to find out which Big Agnes bag matches your camping needs.
Quick answer
Choose the Benchmark 35 if you prioritize packability and warmth in a mummy shape; choose the Echo Park 35 if you want more room to move and a rectangular fit for car camping.
Shape and space: mummy vs. roomy rectangular
The Benchmark 35 uses a traditional mummy shape that increases thermal efficiency and reduces packed size. This design works well for backpackers who need to save weight and bulk.
The Echo Park 35 is built long and wide for campers who prefer extra space to move around at night. It's especially suited for larger statures and car camping where pack size is less critical.
Sleep system compatibility
The Echo Park 35 features the Big Agnes PadLok™ Sleep System and Cinch Pad Sleeve to keep you on your pad all night. This is a bonus for restless sleepers who tend to slide off their pad.
The Benchmark 35 does not include a pad sleeve, so you may need to pair it with a separate sleeping pad attachment or rely on your pad's grip.
Trade-offs at a glance
- Packability: The Benchmark 35 compresses smaller for backpacking; the Echo Park 35 is bulkier but more spacious. If pack size matters most, go with the Benchmark 35.
- Sleep comfort: The Echo Park 35's rectangular shape and PadLok system give you room to move and stay on your pad; the Benchmark 35's mummy shape conserves heat. Pick the Echo Park 35 for car camping, the Benchmark 35 for backpacking.

Product facts
- Benchmark 35°: High-loft synthetic insulation and a water repellent shell keep you warm and dry in any environment. This makes the Benchmark 35 a reliable choice for damp conditions where down bags would lose loft.
