NerdWear. Wear What You Know.

Made to order: Each NerdWear hat is produced specifically for your order using a pre-designed NerdWear Expression and predetermined embroidery specifications. Because your hat is embroidered on demand rather than pulled from mass-produced warehouse inventory, fulfillment may take a few extra days before it ships. Producing only what is ordered helps reduce excess inventory, waste, and unnecessary production costs, which helps us avoid passing those added expenses on to the buyer. Each hat is still produced to the design and specifications established for that product.
