Love the look, but color fades after 2-3 long days in the sun
Size: One Size, Color: Shark/Pfg Palms
Great fit and design, but black fades to brown from sunlight way to quick. Hats are meant to block the sun, so they should be able to hold up to UV better than this hat

As good as the name brands and fits well
Special Size: Midweight, Size: 38W x 28L, Color: Tinted Medium Blue
Just like the name brands, nice and sturdy at a great price. Fits well, feels better than the L's and the W's that's all I'll say there. Solid material, should last years.

Special Size: Midweight, Size: 34W x 28L, Color: Dark Midnight Wash
How can you go wrong with great fitting, comfortable, jeans that look great and cost half of most jeans? I just purchased 3 more pair.

Good if they fit
Special Size: Midweight, Size: 30W x 30L, Color: Dark Midnight Wash
The jeans are great, once I got the right size, but these I brought back to Whole Foods and got charged anyway because Amazon never got them back!! But cheaper than Levi’s
