Ladies and Gentlemen:

We are acting as special Kansas counsel to Event 1, Inc., a Kansas corporation (the “Kansas Guarantor”), relating to the registration by Hanesbrands Inc., a Maryland corporation (the “Registrant”), of certain securities of the Registrant, including debt securities (the “Debt Securities”), pursuant to the Registrant’s registration statement on Form S-3 (as amended or supplemented, the “Registration Statement”) filed with the Securities and Exchange Commission (the “Commission”) on the date hereof, under the Securities Act of 1933, as amended (the “Act”). The obligations of the Registrant to pay the principal of, premium, if any, and interest on the Debt Securities may be guaranteed by the Kansas Guarantor (a “Kansas Guarantee”) and certain other guarantors (such guarantees together with the Kansas Guarantee, the “Guarantees”). The Debt Securities and the Guarantees may be issued pursuant to the Indenture, dated as of August 1, 2008, as supplemented by a supplemental indenture (a “Supplemental Indenture”), by and among the Registrant, the Kansas Guarantor, and the other guarantors named therein, and Branch Banking and Trust Company, as trustee (the “Trustee”).

This opinion letter is furnished to you at your request to enable you to fulfill the requirements of Item 601(b)(5) of Regulation S-K, 17 C.F.R. § 229.601(b)(5), in connection with the Registration Statement.

As to all matters of fact, we have relied on the representations and statements of fact made in the documents so reviewed, and we have not independently established the facts so relied on. This opinion letter is given, and all statements herein are made, in the context of the foregoing.

We express no opinion in this letter as to any other laws, statutes, ordinances, rules, or regulations.

We further consent to the reliance by King & Spalding LLP on our opinions, as if they were addressed to them, in rendering their opinions to the Registrant on the date hereof, it being understood that our opinions speak only as of the date hereof and that no such reliance will have any effect on the scope, phrasing, or originally intended use of our opinion.
