MEMORANDUM OPINION OF THE COURT

Because we write for the parties only, the background of the case need not be set out. We reject the appellant’s argument that the prison regulations at issue in this case violate the First Amendment of the United States Constitution. Because the prison restrictions on the wearing of certain apparel were reasonably related to legitimate penological interests, we affirm the District Court’s summary judgment in favor of the defendants.

Although prisoners’ personal liberties are certainly curtailed during incarceration, the Supreme Court has made it clear that prisoners “do not forfeit all constitutional protections by reason of their conviction and confinement in prison.” De-Hart v. Horn, 227 F.3d 47, 50 (3d Cir. 2000) (quoting Bell v. Wolfish, 441 U.S. 520, 545, 99 S.Ct. 1861, 60 L.Ed.2d 447 (1979)). “Inmates clearly retain protections afforded by the First Amendment, ... including its directive that no law shall prohibit the free exercise of religion.” Id. (quoting O’Lone v. Shabazz, 482 U.S. 342, 348, 107 S.Ct. 2400, 96 L.Ed.2d 282 (1987) (citations omitted)). However, certain restrictions on inmates’ exercise of these constitutional rights are justified by the valid penological objectives of deterrence of crime, rehabilitation of prisoners, and institutional security. See id. at 50-51.

In Turner v. Safley, 482 U.S. 78, 107 S.Ct. 2254, 96 L.Ed.2d 64 (1987), the Supreme Court concluded that “when a prison regulation impinges on inmates’ constitutional rights, the regulation is valid if it is reasonably related to legitimate penological interests.” Id. at 89, 107 S.Ct. 2254. Turner counsels consideration of the following four factors:

“First, there must be a ‘valid, rational connection’ between the prison regulation and the legitimate governmental interest put forward to justify it” and this connection must not be “so remote as to render the policy arbitrary or irrational.” Second, a court must consider whether inmates retain alternative means of exercising the circumscribed right. Third, a court must take into account the costs that accommodating the right would impose on other inmates, guards, and prison resources generally. And fourth, a court must consider whether there are alternatives to the regulation that “fully accommodate[ ] the prisoner’s rights at de minim-is cost to valid penological interests.”

DeHart, 227 F.3d at 51 (quoting Waterman v. Farmer, 183 F.3d 208, 213 (3d *136 Cir. 1999) (internal citations omitted)). The District Court correctly applied Turner and concluded that the regulations at issue did not violate the First Amendment.

We also agree with the District Court that, assuming for the sake of argument that the Religious Freedom Restoration Act, 42 U.S.C. §§ 2000bb through 2000bb-4, applies, the record does not show that the regulations impose a “substantial burden” on religious exercise.

We have considered all of the defendants’ arguments and see no basis for reversal. The judgment of the District Court is therefore affirmed.
