We’ll cover shipping forever after your first order because you believed in us first.

Let’s be honest… we know you’ll be back 😉

And we take care of those who trusted us from the beginning.

100 days to decide. That’s twice as long as our baby slept last year.


Use it. Wash it. Live it. Send it back.
We won’t cry (okay, maybe just a little).

But truth is? Hardly anyone does.

And if you do… tell us why. We actually care.

Text us. We always answer


We’re real parents... no bots, no scripts.

Ask us anything on WhatsApp

We reply like parents do: eventually, and with love

If it survived our kids… and convinced thousands of parents, it might be just what you need.


That’s why today, we’re proud to maintain an average customer rating of 4.7 out of 5. Not because we’re perfect, we’re not.

We still have a long road ahead before we hit 5.0, but we’re here for it. And we’d love to walk it with you.

Lo recibes en una cajita de cartón reciclado en una presentación impecable.

La primera impresión es que es más bonito que en foto, un diseño alegre y colorido y lo siguiente cuando lo tocas....es tan amoroso...suave y mullidito..

Para mí es muy importante que sea hipoalergénico y que me aseguren que el tejido está libre de tóxicos.

Es 100% algodón y el 2.5 tog te asegura que el bebé va a estar calentito en ambientes de hasta 22°.

Los detalles también son importantes, con doble cremallera para que podamos cambiar los pañales sin desvestir la parte de arriba, las cremalleras están tapadas para que no se arañen o raspen con ella.

Los botones tipo corchos que tenemos en las mangas nos dejan ajustar la talla según crezca el bebé y tiene un ceñido en la cintura para más protección y comodidad.

No solo para usarlo en casa...siempre viene genial tener un saquito que abriga.

Si te ha resultado útil mi opinión, puedes hacérmelo saber pulsando el botón útil 😀

Lo he comprado para mi bebe de 4 meses, en talla de 3-6 meses, pero es muy pequeño, realmente no mide 70 cm de largo. Si no me equivoco a penas mide 63 cm y va justo para mi bebé. Hay que comprar una talla más grande. Es calientetito y cómodo para dormir, con una pijama de algodón por dentro.

De las mejores compras que he hecho últimamente. El saco es genial, de muy buena calidad y precioso. Se lo he regalado a mi cuñada para mi futuro sobri y la ha encantado. Lo mejor es que es de algodón y tiene un tacto muy agradable.

Nos ha ido genial con nuestra hija. En nuestra habitación nunca tenemos menos de ,18°C y este nos venía mejor que los de 2.5 TOG

We offer two sizes:
• 0 to 6 months: 70 cm long. Not extendable.
• 6 to 18 months: 80 cm long and adjustable to 65 cm using the rear buttons.

Don’t worry too much about the weight. Measure your baby’s length and choose the size accordingly. The sleeping bag has snap buttons to adjust the fit around their body.

The 0-6 month model can be used from the first month, but we recommend waiting until the baby weighs at least 3 kg and has some arm mobility. If in doubt, reach out to us on WhatsApp.

This is a 2.5 TOG model. It’s ideal for room temperatures between 16ºC and 20ºC (cool rooms, mild winters, homes without strong heating). Not recommended for summer or rooms above 21ºC.

No. It’s 100% cotton with certified Oeko-Tex filling that retains warmth without overheating. Parents say it’s warm but breathable — cozy, not stifling.

Yes. All fabrics are certified OEKO-TEX Standard 100. Free from toxins, dyes, and pesticides. Safe for sensitive skin.

Extremely. Here’s why:
• Double zipper with fabric cover to prevent rubbing.
• Snap buttons on sleeves to prevent arms from slipping inside.
• Rear clips to reduce length and avoid excess fabric.
• Official safety certifications in the UK, Europe, and the US (BS 8510:2009, EN 16781, CPSC & CPSIA).

Of course. Up to 60ºC. The fabric is durable and air-dries well. If tumble drying, use low heat.

It’s thicker than some sleeping bags, so it may take a bit longer. We recommend natural drying. Avoid ironing.

Yes. The double zipper lets you open just the bottom part for diaper changes without fully undressing your baby. Many parents highlight this as a key feature

Not at all. It comes neatly folded in a compact box — perfect for gifting. It’s not feather-filled, but cotton-based: cosy yet manageable.

The ergonomic design and adjustable buttons help it stay put. It won’t twist or come loose during even the most restless nights.

Safety, thoughtful design, and lasting quality. This product has been tested by hundreds of families, passed all EU and US safety tests, and is built to last.

Yes. You have 100 days to try it out. But fair warning: very few come back. Ask the parents already using it.

We get it — it feels like a lot for one item. But after a week of use, you’ll wonder how you ever managed without it. A good sleeping bag isn’t a luxury — it’s better sleep for everyone.

Now it’s your move.

They say babies don’t come with a manual.

But some products feel pretty close.

This sleeping bag? It’s the one thing parents keep buying again, gifting to others, and raving about in the reviews.

Not perfect. But close.

Try it for 100 nights. Sleep on it — literally. If it’s not for you, send it back.
