The Only Machine Washable Makeup Bag You'll Need

The Lay-n-Go COSMO is a patented layflat-to-drawstring cosmetic bag that is fully machine washable — cold water, gentle cycle, hang dry. It comes in three sizes (16, 20, and 22 inches), is under $40, and is the only makeup bag on the market that opens completely flat so you can see and reach everything at once.

Why machine washable matters more than people realize

Most makeup bags are not machine washable. They're made with materials that warp, adhesives that dissolve, or linings that trap moisture and grow mold. The result is a bag that looks fine on the outside and is quietly disgusting on the inside.

Foundation gets on the lining. Mascara smears. A lip gloss cap comes loose. Hand lotion pools in the bottom. Over weeks and months, the inside of a typical makeup bag becomes something you'd rather not think about too hard.

The COSMO solves this with a simple feature that most bags skip: it's machine washable.

Cold water. Gentle cycle. Hang dry. That's it. The bag comes out clean, the material holds its shape, and the drawstring mechanism works exactly as it did before. You can wash it as often as you need to.

How to wash a Lay-n-Go COSMO

1. Empty the bag completely — remove all products and shake out any loose powder
2. Turn it inside out if possible to expose the lining
3. Machine wash cold, gentle cycle
4. Hang dry — do not put in the dryer
5. Once dry, it's ready to use

That's the entire process. No special detergent, no hand washing, no dry cleaning.

Why the COSMO is different from other makeup bags

Most cosmetic bags are pouches — you reach in and dig. The COSMO lays completely flat when open, like a circle on the counter, with every product visible and reachable at once. When you're done, you pull the drawstring around the perimeter and everything cinches closed.

The layflat-to-drawstring mechanism is patented. Lay-n-Go holds 7 US utility patents on the design — there's no other bag that works the same way.

Combined with machine washability, it's the most practical cosmetic bag for daily use. You get full access to your products when it's open, and a clean bag whenever you need one.

Which size is right?

All three COSMO sizes are machine washable and under $40:

COSMO 16 — Compact. Best for a minimal daily kit or travel essentials.

COSMO 20 — Mid-size. The most popular size for everyday use — fits a full makeup kit without taking over your counter or bag.

COSMO 22 — Large. Built for full collections, palettes, and brush sets. Plenty of room to spread out.

FAQ

Is the Lay-n-Go COSMO really machine washable? Yes. Cold water, gentle cycle, hang dry. All three sizes.

Will washing it damage the drawstring mechanism? No. The drawstring is designed to hold up to regular washing. Hang dry to preserve the shape.

How often should I wash my makeup bag? Once a month is a reasonable baseline for daily-use bags. After any significant spill, wash it immediately.

Does it shrink in the wash? No, as long as you hang dry. Do not put in the dryer.

What material is the COSMO made from? Water-resistant polyester. It's designed to handle moisture, which is part of why it washes so cleanly.

Where can I buy one? All three sizes are at layngo.com and on Amazon, under $40.
