cool polar bear, featuring an open-mouthed, friendly expression with visible teeth. The polar bear wears modern, trendy sunglasses. Use a monochromatic color scheme for the bear, with the sunglasses in a striking contrasting color to make them stand out. Above the bear's head, integrate the bold, uppercase text "MAMA" in a playful yet strong font that complements the bear's relaxed and fun vibe. Utilize a double exposure art style within the bear's silhouette, blending elements of icy landscapes and snow textures to add depth and artistic intrigue. Ensure all elements are centered on a plain white background, featuring crisp, clean lines perfect for t-shirt printing.
