Our classic menswear style pajama collection, Bella PJs, have become one of our top selling Pajama collections of all time. Our Bella PJs are known for their amazing softness, thanks to the fine Peruvian Pima cotton. Peruvian Pima cotton is the most luxurious Pima cotton around. Due to its ideal growing conditions, the extra-long staple length and the hand harvesting of the Pima Cotton in Peru. It has high quality durability, and a lustrous sheen to the fibers.
These are the soft, snuggly, comfy PJs of your dreams. The Bella PJ collection began with one simple style over eight years ago. It has expanded every year since. Each season, we add new colors, prints, styles and even fabrics. Over the years, we have done multiple Bella PJ collaborations. These include Bella PJs in Bridal, Bella PJs in flannel, silk, and fuzzy shearling. We have updated and added new styles too. Get the lowdown on every Bella style here:
