Is the FC10 warm enough for cold-weather camping?

No insulation value is stated, so treat it as a three-season or warm-weather pad. For freezing nights, pair it with a separate insulated pad or a closed-cell foam layer underneath.

How thick is it, and does it include a pillow?

The body is 6.5 cm thick, and the pillow section is 10 cm. The pillow is built into the pad, so you don't need to pack a separate one.

How small does it pack?

It rolls down to about 10 x 30 cm and weighs around 600 g, which fits inside most backpack side pockets or a small stuff sack.

Does it come with a pump or stuff sack?

The listing doesn't confirm accessories. Check the box contents before you rely on an included pump; a lightweight inflator bag works well with pads like this.

Is the material durable enough for rough ground?

The nylon-TPU composite with a double-layer sealed coating is abrasion-resistant and waterproof. Still use a groundsheet on sharp rocks and roots to avoid punctures.
