La Funda de Almohada Impermeable Prim

The waterproof layer holds up perfectly—no damp spots on my pillow after a sweaty night, and it doesn't crinkle or feel plasticky under the case. I've washed it twice already and it still fits snug without bunching.

I was skeptical about sleeping on a waterproof cover, but this one is completely silent and doesn't make the bed feel plasticky at all. My pillow stays fresh for weeks now, and it's been a total game-changer for keeping things clean without any extra fuss.

The waterproof layer actually holds up well—I spilled a full glass of water on it during the night and the pillow underneath stayed completely dry. Only giving four stars because the fabric crinkles a bit when you roll over, but that's a fair trade for the protection.
