IPF Technical Rules book 2009 T Shirt / Supportive Shirt A T Shirt or support shirt (the support shirt shall be of one ply stretch material) of any colour or colours must be worn under the lifting suit during the performance of the squat and bench press, but is optional for the men in the deadlift. A combination of the two is forbidden. Women must wear a T Shirt or support shirt while competing on all lifts. Support shirts as approved by the Technical Committee and noted in the list of approved equipment and clothing issued periodically by the committee may be worn for all lifts. All of the conditions as defined for the T Shirt also apply to the support shirt. The support shirt cannot be so long as to cover the buttocks when tucked into the suit and therefore serve as extra support. In addition seams may only be placed in the positions indicated in the diagram. The T Shirt is subject to the following conditions: (a) Does not consist of any rubberized or similar stretch material. ( Does not have any pockets, buttons, zippers, collar, or vee neck. © Does not have reinforced seams. (d) Is made of cotton or polyester or a mixture of cotton and polyester. Denim is not acceptable. (e) It shall not have sleeves which terminate either below the elbow or at the deltoid. Lifters may not push or roll the sleeves of the T-Shirt up to the deltoid when competing in IPF competition. T-Shirts must not be worn inside out. The “Support shirt” as used in the squat and deadlift may be “sleeveless”. (f) Is plain or the official T Shirt of the contest in which the lifter is competing or bears the badge and or inscription of the lifter’s nation, national or regional federation or sponsor. That which is offensive or likely to bring the sport into disrepute is not allowed. The sponsor’s logo must also conform to item 10 under Inspection of Personal Equipment (Sponsor’s Logos).
