These are the new Zip Leggings by Rag & Bone. They are the legging jeans that feature a six inch inseam zipper. The one above is the Seal wash, which is a coated black. They are also available in the Shoreditch and a Coated Navy. All the styles will be available later next month.
From a very personal experience, these jeans are amazing. I have them in the Shoreditch wash and lived in them for quite some time. They can literally be worn with everything. You can keep the ankles zipped for a more streamlined look or unzip them and wear them casually. They are so perfect! I cannot wait to see the other washes that will be available.
