- David S.Verified BuyerReviewingCocoon Swaddle Bag 2.5 TOG WillowWhat is your favorite feature of the Cocoon Swaddle Bag? Easy to use, Cosy fit, Soft materialRated 3 out of 5 stars1 week agoGreat and comfy product but shrinks!
I have and have had purchased for us several sleeping bags.
The quality, comfort and features are great but the impact and shrinkage of machine washing these is beyond what I would expect. (Using a delicate wash cycle in a Bosch series 6).
EergoPouch4 minutes agoHi David
Thank you for taking the time to share your feedback. We're sorry to hear about the shrinkage after washing.
All of our fabrics are pre-washed and undergo shrinkage testing before production. However, due to the organic nature of our fabrics, some minor shrinkage can occasionally occur depending on washing conditions such as agitation strength, water temperature and types of detergents used.
If you feel that your pouch has shrunk significantly, please let our customer support team know. They will be reaching out to you to assist further and ensure this is resolved for you.
We truly appreciate you bringing this to our attention and thank you for your support.
