24 Size Guide

    The Perfect Percale Pillowcase

    Our NEW Envelope Closure Pillowcases have a beautiful side envelope closure to keep your pillow hidden at all times. These pillowcases sleep cool and crisp. Perfect for a hot summer day. Upgrade your sleep experience with extra pillowcases so you always have a set on hand.

    • Design

      A pillowcase is a personal thing. You rest your head on one 365 nights a year. We set out to design a set of pillowcases you would love to sleep on. Every. Single. Night. Our beautiful envelope closure keeps your pillow neatly tucked in. The face has a clean look with no lines. Our luxe combination of Percale weave and Supima cotton deliver a great sleep night after night, and look great doing it. Pillowcases see a lot of use, and abuse, it's best to wash and change them regularly.  


      100% ‘seed-to-stitch’ Made in the USA bedding. Our entire manufacturing process - from growing the cotton, to spinning the yarn, to weaving the fabric, to cutting and sewing - is done in America. Learn more about our manufacturing partners here. 

      Supima® Cotton

      Supima® cotton. Our sheets are made from California-grown Supima®, one of the finest - and rarest - cottons in the world. It has a 35% longer staple than regular cotton, making it 45% stronger and considerably softer. We wouldn’t settle for just any cotton, less than 1% of all cotton produced meets the criteria to be labeled Supima®. Read more about Supima® cotton here.

      Percale Weave, 250 Thread-Count

      We chose the Percale Weave because it is cool and crisp, highly breathable, exceedingly durable, and will continue to get better with use. Despite what you may have heard, 250 thread-count is the ideal thread count for a great night’s sleep. Learn more about thread-count here. 


      Formaldehyde, an ingredient found in most “wrinkle-free” products, is a known carcinogen, so we said ‘yes' to wrinkles and ‘no' to wrinkle-treatments. 

      Radical value

      We've cut out all of the things that drive up prices without adding value, like big store fronts and pricey marketing campaigns. And, we sell our sheets direct to you - straight from the factory floor to your bedroom - without a middleman or their mark-up. This way, we can offer sheets of greater quality than our competitors', for less than half the price. 

      100 Night Sleep Trial

      You’ve got 100 nights to decide if you like our sheets. If you're unhappy with them for any reason, we’ll cover the cost of return shipping, and issue a full refund. FREE DOMESTIC SHIPPING.

    Love Authenticity

    I purchased the envelope pillowcases as an add on item to the sheet set I purchased earlier. I love the quality of Authenticity 50. The pillowcases keep my pillows inside and wash beatifully.

    Not impressed

    The sheets are ok but nothing special at all. We cannot believe how much we paid for sheets that are 2 to 3 times the cost of much higher quality sheets. We really love to buy Made in US, but feel like we lost on this one. :(

    Awesome Pillowcases

    I’ve never had envelope closure pillowcases before, but since there were no standard pillowcases available, I decided to try them. They are amazing and so neat. I washed them in cold water as recommended, and although I could have ironed them to make them crisp, I enjoy the softer look. These are the pillowcases of my childhood, where I would turn over my pillow in the summer to have a cool pillowcase underneath. I never found that with hi thread count sheets. I have these pillowcases in standard and queen and if someone gave me 1000 thread count sheets, I’d stick with my lovely, grown and made in USA Authenticity 50 sheets. Thank you!
