Winter Onesie

Mountains Print




This is the best onesie.

The outer shell is a BangBangCrash exclusive design, digitally printed onto high quality 100% GOTS certified organic cotton drill (soft, breathable and durable,) and lined in the softest 100% organic cotton (Oeko-Tex certified) grey fleece. The onesie has a YKK zip-down front, inseam pockets, and stretchy organic cotton cuffs. The hood is lined with luxury faux fur. This is, hands down, the cosiest and more luxurious onesie you will ever own. Once you put it on, you will not want to take it off.

Each onesie is made-to-order in our Bristol studio. Production can be up to 4 weeks at peak times. If you need your item for a certain date please get in touch here or let us know at point of purchase so that we can be aware of your timescale. Customisation is possible, just drop us a line. We practice ethical, sustainable and transparent manufacturing. You can read about our ethics & production methods here.

These onesies are unisex, please select a size from the drop-down menu, using your chest/bust circumference as reference (This is not the size of the onesie, please use your actual chest size – for help with measurements click here.) If you aren’t sure what size is best for you please select “made-to-measure” and include either your chest measurement and height, or bust, waist, hips and height measurements in the notes section at the checkout. As each onesie is made-to-order customised sizing is easy for us to do, and there is no extra cost for you.

Notes on sustainability: Organic cotton is grown without using synthetic pesticides and fertilisers and without the use of genetically modified crops. It uses 91% less water than non-organic cotton, and produces far fewer greenhouse gases. The naturally off-white colour of the organic cotton drill is because it has undergone a more gentle and less polluting bleaching process. Find out more here

The hood is lined in faux fur fabric that is left over from a previous design. When this runs out the onesie will be adapted to have an organic cotton lining.

Digital printing is the most environmentally friendly printing method as it is extremely precise and does not rinse excess inks into the water system.

When it comes to sustainability, there are pros and cons with all fabrics and all production methods, but at BangBangCrash we aim to always make the most-sustainable choice available, and ensure that you as a consumer are as informed as possible. As with all our garments, production takes place in Bristol using energy from renewable resources.
