To ensure that the material reception conditions provided to applicants comply with the principles set out in this Directive, it is necessary to further clarify the nature of those conditions, which should include not only housing, food and clothing but also personal hygiene products. It is also necessary that Member States determine the level of material reception conditions provided in the form of financial allowances or vouchers on the basis of relevant references applied to ensure adequate standard of living for nationals, such as, depending on the national context, minimum income benefits, minimum wages, minimum pensions, unemployment benefits and social assistance benefits. It is not, however, necessary for the amount granted to applicants to be the same as for nationals. Member States should be able to grant less favourable treatment to applicants than to nationals as specified in this Directive. Member States should also have the possibility to adapt the level of financial allowances or the vouchers granted to applicants in regions referred to in Article 349 of the Treaty on the Functioning of the European Union (TFEU), provided that the standard of reception conditions provided for in this Directive is ensured.
