BUTTERY SOFT

This zip up sleeper is the SOFTEST and COZIEST GOTS certified organic cotton sleeper I have ever had for my babies. I reach for the zip romper in the two colors I have every time they are in the clean laundry pile!!! Thicker and better quality than I have seen from other popular organic cotton baby clothes companies as well. I appreciate that the bigger sizes have the fold over cuffs too!

Great product, amazing company!

These sleepers are so soft! The little pocket pals are absolutely adorable. I ordered the used bundle of 3 and received an email within a couple of days that they were out of the size I had selected so they were sending me brand new items instead at no extra charge. If you’re hesitating to make a purchase, you don’t have to worry about quality of product or service with OLT! Extremely impressed with both and I never leave reviews but this company deserves it.

We LOVE this romper!

We LOVE this romper! The material is nice and thick and feels softer after every wash! Also love that the feet coverings are optional.

Very well made!

These are super cute, very well-made, and the colors are beautiful. I love all the thoughtful features.

That said, they do seem to run a bit small, which was disappointing—I thought I had ordered a size up so they would last longer. Unfortunately, they’ll likely only fit for another month, when I had hoped they’d fit for at least 3 to 4 months with a little room to grow.

My baby is just barely three months old, and they're already fitting pretty snug, where other 3-6 month clothes are still loose. So all id say is just size up but definitely buy some!

The only thing my little one wears now!

These are my new favourite clothes for my little guy. It’s literally all he wears now. They’re so easy and simple to put on and so incredibly soft and comfortable. I bought three and immediately ordered three more. I have 6 now and they’ve literally become his uniform. So excited to trade up when he grows.

Very luxurious

These sleepers are so well made. The zipper is much sturdier than a standard sleeper which is nice. The material is so buttery soft. These are my favorite sleepers we have right now!

OLT is the BEST!

These rompers are our absolute favorite! The super-soft 100% cotton, fold-over cuffs on both the arms and legs, and the convenient two-way zipper are all features we love—and we haven’t found them all together in any other brand. You can truly feel the care and thoughtfulness in the craftsmanship of each piece. The pocket pals are an adorable bonus! We just completed our first “trade-up,” and the process was seamless—unlike the rompers, which have fantastic seams. We’re excited to continue enjoying OLT as our baby grows!

Super soft and durable pajamas

We love everything about the zipper romper- from how it can switch from play to sleep, the super soft and durable material, the colors, and the functionality is all 5 star! These are a new family fav for sure!

Will not buy any other jumper

This jumper is extremely well thought out. From the foldable feet and hand covers to encourage sensory play in the day and warmth in the night. To the off set zipper so it doesn't bunch when putting my baby in a carseat. To the buttery soft but still somehow very hefty and thick fabric. To NO GIANT SEAMS!!! My baby is already had sensory issues and this had helped so much. I truly never want to put her in another brand of jumper. The 40% trade up program makes that completely doable.

Super comfy

We love the Rompers! So soft and smooth and easy to wear and the best part is that the feet are not covered so my son can wear it to sleep or even to daycare. Love the different colors as well. Can't wait to order more when he sizes up.

Our favorite! Such great quality

My son loves wearing the zip romper with his pocket pals! It’s the most adorable thing. The fabric is so nice and thick too! They are a worthy investment pieces and highly recommend

You'll want to hug your baby more!

Not kidding, "You'll want to hug your baby more" should be the tagline for these rompers, because that's what they make you do. The fabric is so darn soft and cozy, perfect for snuggling (and make the nap traps more tolerable, lol). My 17-month-old absolutely loves putting his arms through and never gets stuck because of the smooth material. The two-way zipper is obviously a MUST. And how cute is the pocket for the pal? I wish these came with bigger sizes for my 4 year old...and for the parents!

So soft!

As usual, we LOVE the feel and ease of these jammies. And this color is beautiful! The only bummer is no more fold-over feet at this size which would be really nice to have.
