Is the Mad River 40 warm enough for summer camping?

Yes for mild nights around 40°F and above, especially with a pad and baselayers. Below that, most sleepers will want a warmer bag or a liner.

Does it pack small enough for backpacking?

The 650-fill down compresses well, and it comes with a stuff sack. It fits comfortably in most 40–50 liter packs alongside other gear.

Is it good for side sleepers?

The mummy shape is snug through the shoulders, so side sleepers who move a lot may prefer a wider cut. Back and stomach sleepers generally find it fine.

Can it handle wet weather?

The shell resists light moisture and condensation, but it is not waterproof. Keep it dry and air it out, since wet down loses loft and warmth.

What comes in the box?

The sleeping bag and a stuff sack. A storage sack for long-term loft is not included, so hang or loosely store it between trips.
