The Tyndale Classic Short Sleeve FR T-Shirt is a 5 oz. FRMC® jersey knit base layer with a 4.7 cal/cm² Arc Rating (CAT 1), built for workers who need lightweight FR protection with moisture-wicking and fast-drying performance. The shirt uses inherently flame resistant fabric and is made in the USA by Tyndale. Designed as a base layer with a loose fit, the F025T provides a short-sleeve option for wearing under a primary FR garment. Its FRMC® jersey knit combines lightweight construction with moisture-wicking and fast-drying material to help manage moisture during wear. The shirt's 4.7 cal/cm² Arc Rating and CAT 1 designation provide its stated arc-protection values for comparison with the PPE requirements established for the specific task and hazard. Flat-lock seam technology reduces raised seam bulk against the skin, while the tagless construction eliminates a conventional neck tag. These details make the F025T specifically suited to close-to-body wear as part of an FR clothing system. The shirt also features a crewneck design and the straightforward construction of a classic short-sleeve T-shirt. Because the fabric is inherently flame resistant, the FR protection is built into the fiber itself and cannot wash out or wear off regardless of how many times the garment is laundered. For care, you should always follow the instructions on the garment label,. Generally, you should wash FR garments in warm water, tumble dry low or line dry to limit shrinkage, and avoid bleach, fabric softeners, orand starch. Properly cared for, this garment maintains its flame resistant properties for the useful life of the garment.
