The Bighorn's clearest buying point is right in its name: 100% virgin wool. The Arcturus Bighorn 100% Virgin Wool Blanket - Mocha is for someone deliberately comparing that material choice, rather than someone who simply wants the smallest emergency layer available.

The Mocha color may suit the rest of your bedding, but the selected size will have a much bigger effect on everyday use and storage.

Dimensions With a Real Carrying Cost

Twin: 64 by 88 inches, approximately 4.5 pounds.
Queen: 90 by 96 inches, approximately 6.7 pounds.

Those figures make it easy to compare the two sizes honestly. The Queen adds shared coverage, while the Twin is the more manageable option when one person's extra layer is all you need.

Choose the Blanket Job First

A wool blanket can be draped over a seat, folded under another layer, or spread across a bed. That flexibility is useful at a vehicle-supported camp or cabin, where moving it a few feet matters more than carrying it all afternoon.

For sleeping outside, it still needs an appropriate surface and weather arrangement. Wool content doesn't establish a particular sleeping-temperature rating, and the blanket isn't automatically a shelter from rain.

An Ownership Decision Too

Read the care directions before choosing a large wool item. A blanket you'll use repeatedly needs a realistic washing, drying, and storage routine. The heavier size isn't much of a benefit if you avoid taking it out because handling it afterward is inconvenient.

I'd compare the Bighorn when all-wool construction is a real preference and the stated weight is acceptable. I'd choose Twin or Queen from actual coverage needs, not the assumption that bigger is always better. It is most convincing as substantial extra bedding with a defined place to live.
