Outdoor pillow covers let you change colors by season and wash the fabric without replacing the insert. Most are sold at 18 by 18 inches without inserts, in packs of 2 or 4, so the main differences are fabric, coating and how they can be washed.

We compared outdoor pillow covers on fabric, water resistance, zipper, pack size and care. All picks here are covers only. For pillows with inserts, see Best Outdoor Throw Pillows, or browse the Outdoor Cushions category.

How to Choose Outdoor Pillow Covers

Size and Insert

Match the cover to your insert size. A cover the same size as the insert looks full, and some people size the insert up for a plumper look.

Fabric

Polyester and canvas covers handle sun and rain well. Linen and chenille feel softer but suit covered spaces better.

Water Resistance

Coatings help water bead off, but covers alone do not keep inserts dry in heavy rain. Pair them with water-resistant inserts and bring pillows in during storms.

Washing

Most outdoor covers can be machine washed. Check the temperature and drying limits on each listing.

How We Evaluate Outdoor Pillow Covers

For this guide we compared pillow covers on fabric, water resistance, zipper, pack size and care. We read each maker's specifications and flagged a listing whose title names a fabric brand its description does not. Most listings here had no rating data in our product feed, so ratings did not decide the order. We did not handle these covers ourselves, every figure comes from the maker's listing, and we never repeat a waterproof claim as our own.

Variants of one listing count as a single product, and we would rather list a few strong picks than pad the list. Our full process is on the How We Review page.

FAQ

Do outdoor pillow covers come with inserts?

None of the picks in this guide include inserts. Buy outdoor-rated inserts to match.

Can I wash outdoor pillow covers?

Most can be machine washed. Amazon Basics allows warm water, while MIULEE and Artscope ask for cold water on a gentle cycle.

Are outdoor pillow covers waterproof?

Many are water resistant. Water can still reach the insert in heavy rain, so store pillows dry.

Final Verdict

The Amazon Basics 4-piece set is our top pick for its clear care label and OEKO-TEX certification. MIULEE offers the widest solid colors, and Artscope has a natural linen look.

Pyonic has bold floral prints, RABUSOFA is a two-tone set of 4, and Fancy Homi is the softest chenille option. For inserts, see Best Outdoor Throw Pillows, and for seat cushions see Best Outdoor Cushions.
