Is the 20°F rating realistic?

Treat it as a three-season bag for mild nights. Owners report being cold around 22–28°F, and some suggest it behaves more like a 35°F bag.

Do I need a sleeping pad with it?

Yes. The Padlok sleeve is central to the design and takes pads 25–30 in. wide. Without a pad the bottom has little insulation.

Will it fit a tall person?

It is a long, wide bag sized for campers up to 6 ft 6 in., with an 80 x 30 in. footprint.

How small does it pack?

Not very small. It weighs about 4 lb 12 oz and owners say it packs large and does not compress much, so it suits car camping more than backpacking.

What comes in the box?

The bag, a mesh storage sack and a smaller stuff sack. The sleeping pad is not included.

The best new price is $200 at eBay as of November 5, 2026, the low end of its recent range across five stores.
