In short

Fine for cotton and synthetics. They compress without damage and protect against damp and insects.
Destructive for wool and down. Both insulate by trapping air.
Never for leather or anything structured. Compression creases leather permanently and distorts tailoring.

Vacuum bags are excellent for some fabrics and destructive for others, and the difference is not obvious from the packaging.

They compress without damage and protect against damp and insects. This is what they are genuinely good for.

Both insulate by trapping air. Compressing them crushes the loft, and it does not always come back.

Compression creases leather permanently and distorts tailoring.

Are vacuum bags bad for clothes?

For wool and down, yes — compression crushes the loft that provides warmth. For cotton and synthetics they are perfectly fine.

How long can clothes stay vacuum-packed?

Under a year for anything. Long-term compression sets creases even in fabrics that tolerate it initially.
