Warm and surprisingly light

Took this on a 4-day trip in the Wind Rivers and it handled nights in the low 30s with ease. The FireLine Pro Eco insulation lofts nicely and compresses better than my old synthetic bag. At this sale price it's honestly a steal.

Great 3-season bag

Comfortable down to about 40°F for me, probably lower with better sleepwear. Packs down small for a synthetic. The PFAS-free DWR shed morning dew no problem. Docking a star because the stuff sack is a bit tight to get it back in.

Good but runs cold for me

I'm a cold sleeper and needed to add a liner even at 45°F. Build quality is excellent and the fabric feels durable, just know the comfort rating may be optimistic if you run cold like I do.

First real backpacking bag

Upgraded from a cheap car-camping bag and the weight difference is night and day. Saved over a pound on my pack weight. Slept comfortably through a chilly spring night in the Smokies and it kept me warm without overheating. The mummy shape is snug but that's the point.

Solid synthetic option

I prefer synthetic for damp Pacific Northwest trips and this one has performed great through two seasons. Dries fast if it gets wet. Zipper glides smoothly and never snags.

Zipper snags

The bag is warm and light but the zipper catches on the fabric baffles regularly, sometimes several times a night. Frustrating when you're half asleep.

Great value at the sale price

I've used this on a dozen trips since spring. It's held its loft, the water repellent finish still beads water, and the regular length fits my 5'11" frame with a little room to spare. For under $75 this competes with bags twice the price. Big Agnes quality is real.
