Soft material, not quite as warm as polar fleece, but still cozy. I love the pattern and am really happy with the onsie.
The loose onesies are my favorite. I can lounge, sleep in them, or take then to the park and be comfortable. They are soft with fleece lining and warm enough.
Excellent craftsmanship! Love the colours, love the design, the material is soft and warm and even though I am only 1,62 m tall it fits just like a onesie should!
PS Even though they have their hands full with halloween season orders they took their time to answer my queries as quickly as they could.
