- undefinedundefinedVerified Buyer1/5/26ReviewingArm Warmers Oatmeal MarleRated 3 out of 5 starsSleeves too tight
This is a great product, great quality. But the sleeves are too tight to fit over a long sleeve onesie on my 6month old. We aren’t able to use it :(
- AndreaVerified Buyer12/26/25ReviewingArm Warmers Oatmeal MarleRated 2 out of 5 starsDo not stretch
These are so hard to get on our LO. They do not stretch and he cries every time. I want so badly to like them because they are warm and let’s us have more flexibility, but we have just been using our sleep sack that has sleeves attached to it over and over because I dread putting this on him.
EUergopouch US1/1/26Hi Andrea
Thank you so much for taking the time to share your feedback. We're really sorry to hear that you've had a frustrating experience with the arm warmers.
We want to reassure you that the 1.0T fabric is designed with stretch to allow for flexibility and natural movement. As the arm warmers are a full-sleeve, jacket-style design, they should still allow your baby to move their arms comfortably whilst sleeping with their arms out.
That said, every baby is different, and we'd love to better understand what you're experiencing. A Customer Support Specialist will be in contact with you to gather more information so we can assist you more accurately.
