I always name this Kavacha as "Shree Gopi Kavacha" in spite of the fact that Its Name is "Shree Krishna Kavacha" (from "Shree Garga-Samhita", Goloka Khanda, Chapter 13, Verses 15-22).
To be precise, the Name should be "Bala Krishna Kavacha", as This Kavacha was sung by Gopis specially for the Safety of Bala Krishna (Infant Krishna).
This is one of The Highest Kavachas (see the last line - "श्रीकृष्ण कवचं परम् - shrIkRRiShNa kavachaM param").
During re-typing into UNIC I have referred to 3 Variants for checking and proofreading:
1) Sanskrit-Hindi Variant of "Shree Garga-Samhita" ("GARGA-SAMHITA", SANSKRIT-HINDI, Lala Shyamalala, Shyamakashi Press Mathura, Khemaraj Shree Krishnadas, Venkateshwar Press) - http://vishnudut1926.blogspot.ru/2013/05/garga-samhita-sanskrit-hindi-lala.html
2) This PDF-Variant - http://xa.yimg.com/kq/groups/2182732/252505112/name/Sri+Krishna+Kavacham+-+Garga+Samhita.pdf
