Ladies and Gentlemen:

We are acting as special counsel to Hanesbrands Inc., a Maryland corporation (the “Company”), in connection with the preparation of the Registration Statement on Form S-3 (such Registration Statement, as amended or supplemented, is hereinafter referred to as the “Registration Statement”) filed with the Securities and Exchange Commission (the “Commission”) on or about July 29, 2011 under the Securities Act of 1933, as amended (the “Securities Act”), by the Company and certain of the Company’s direct and indirect subsidiaries which are co-registrants thereto (the “Co-Registrants” and together with the Company, the “Registrants”). The Registration Statement relates to the issuance and sale from time to time, pursuant to Rule 415 of the General Rules and Regulations promulgated under the Securities Act, of an unspecified amount of the following securities: (i) shares of common stock, par value $0.01 per share, of the Company (“Common Stock”); (ii) one or more series of preferred stock, par value $0.01 per share, of the Company (“Preferred Stock”); (iii) one or more series of senior or subordinated debt securities of the Company, which may be guaranteed by one or more of the Company or the Co-Registrants (“Debt Securities”); (iv) warrants to purchase Common Stock, Preferred Stock or Debt Securities (“Warrants”); (v) shares of Preferred Stock represented by depositary shares, each of which will represent a fractional share or multiple shares of Preferred Stock (“Depositary Shares”); (vi) stock purchase units (“Stock Purchase Units”); and (vii) stock purchase contracts obligating holders to purchase Common Stock at a future date or dates (“Stock Purchase Contracts” and together with the Common Stock, Preferred Stock, Debt Securities, Warrants, Depositary Shares and Stock Purchase Units, “Securities”). The Common Stock may be issued with associated rights under the Rights Agreement dated September 1, 2006, between the Company and Computershare Trust Company, N.A., as rights agent.

You have advised us that: (i) the Debt Securities will be issued under the indenture filed as an exhibit to the Registration Statement (the “2008 Indenture”), entered between the Company and Branch Banking and Trust Company, as trustee (together with any successor trustee, the “Trustee”), dated August 1, 2008, as amended and supplemented by the First Supplemental Indenture dated December 10, 2009 among the Company and the Trustee, the Second Supplemental Indenture dated August 13, 2010 among the Company and the Trustee, the Third Supplemental Indenture

In addition, we express no opinion with respect to (i) whether acceleration of the Debt Securities may affect the collectibility of that portion of the stated principal amount thereof that might be determined to constitute unearned interest thereon, (ii) compliance with laws relating to permissible rates of interest or (iii) the creation, validity, perfection or priority of any security interest or lien.

To the extent that the obligations of a Registrant under any Governing Document may be dependent on such matters, we assume for purposes of this opinion that the applicable Governing Document Counterparty is duly organized, validly existing and in good standing under the laws of its jurisdiction of organization; that the applicable Governing Document Counterparty is duly qualified to engage in the activities contemplated by applicable Governing Document; that the applicable Governing Document has been duly authorized, executed and delivered by the applicable Governing Document Counterparty and constitutes the legally valid and binding obligations of such Governing Document Counterparty, enforceable against such Governing Document Counterparty in accordance with its terms; that the applicable Governing Document Counterparty is in compliance, generally and with respect to acting as trustee, warrant agent, depositary or other counterparty, as the case may be, under the applicable Governing Document, with all applicable laws and regulations; and that the applicable Governing Document Counterparty has the requisite organizational and legal power and authority to perform its obligations under the applicable Governing Document.
