Abstract: Disclosed is a thermoplastic elastomer composition having a superior low-temperature flexibility is provided. The thermoplastic elastomer composition may include an amount of about 10 to 15 wt % of a polypropylene-ethylene copolymer; an amount of about 70 to 85 wt % of a thermoplastic elastomer including an olefin-based thermoplastic elastomer and a styrene-based thermoplastic elastomer; an amount of about 5 to 10 wt % of a softener; an amount of about 3 to 5 wt % of a reinforcing agent; and an amount of about 1 wt % or less but greater than 0 wt % of a UV stabilizer based on the total weight of the thermoplastic elastomer composition.
