At the end of the day, you cannot go wrong with any of our carriers - every single one is designed to be lightweight, breathable, supportive, and comfy for both you and baby. If you have read everything and really cannot decide, then we say just go with your gut! You are going to wear what you love, regardless of the textile it is made from and if it makes you feel good, you will wear it!
A great place for community advice is our community Facebook group, Unthreaded. It is a wonderful resource full of useful information and helpful advice!
