When sourcing wholesale cheap joggers, the fabric blend is the most critical factor for balancing cost and quality. Look for a Cotton-Polyester blend (typically 65/35 or 60/40), as this provides the softness of cotton with the durability and shrink-resistance of polyester. Ensure the fabric weight is specified in GSM (Grams per Square Meter); for standard joggers, a weight of 280-320 GSM is ideal for a 'fleece' feel, while 200-240 GSM is better for lightweight 'french terry' styles. Always request a pilling resistance test report to ensure the fabric won't fuzz after a few washes.
