Is a quilt as warm as a sleeping bag at the same rating?

Only if you seal it well. The quilt has no hood or back insulation, so warmth depends on your pad and on closing the neck and sides. Warm sleepers do fine at 20F; cold sleepers should size up in warmth.

Does it work with any sleeping pad?

The SynergyLink straps are made for Therm-a-Rest pads, especially the NeoAir line, but they can wrap other rectangular pads. A pad with good insulation is essential because the quilt has no bottom insulation.

What comes in the box?

The quilt, a stuff sack and a larger storage sack. The storage sack keeps the down lofted between trips.

How does it compare with the Therm-a-Rest Oberon or Hyperion bags?

The Vesper is lighter and packs smaller than those bags but gives up the hood and full enclosure. Choose it for weight savings; choose a hooded bag if you sleep cold or move a lot.

Is the down treated for wet weather?

The shell is water resistant and the materials are PFAS-free, but the down is not a waterproof barrier. Keep it in the stuff sack in rain and dry it thoroughly after damp trips.

Can two people share it?

No, it is a single-person quilt. Couples typically use two quilts or a dedicated double quilt.
