Which brand is known for casual shirts as well as sweatshirts?

C.C. Filson is recognized for its rugged outdoor clothing, but its core offerings primarily focus on durable outerwear, vests, and accessories suited for the outdoors, rather than casual shirts or sweatshirts. This aligns more with a specific niche devoted to workwear and outdoor enthusiasts, which may not include a broad range of casual styles like shirts and sweatshirts.

In contrast, the other brands listed have a well-established reputation for offering a variety of casual clothing items. For instance, Buck Mason is known for its modern takes on classic American staples, including casual shirts and sweatshirts, appealing to a contemporary casual market. Similarly, Brooks Brothers specializes in traditional menswear that features a range of formal to casual shirts and has made inroads into relaxed styles as well, including sweatshirts. Bravado, on the other hand, is often associated with music-themed apparel and merchandise rather than a dedicated collection of casual shirts and sweatshirts.

Thus, C.C. Filson stands out because its primary branding does not coincide with the casual wear categories indicated by the other options, making it less relevant for the question about casual shirts and sweatshirts.
