Providing full coverage of the head and neck and ears and upper chest, Ninja underscarves are a new design, similar to the full underscarf with the only difference being that this one is actually fitted around the neck making it a more comfortable experience. Plain are the most common ones in Ninja underscarves but new designs are now coming out meaning that you would be able to get them with lace, criss cross peaks and criss cross contrasting colours. You can wear these underscarves all year round and they are great for muslimahs who like to hit the gym and find it tough to keep the hijab in place as it might move, it also meets the requirement of the full underscarf ensuring that if you need to wear sheer or see through hijabs, then you are covered fully. These are mostly available in cotton jersey and are quite light weight.
