As you know, I sometimes like to review much-hyped about things even though they aren't in the ethical or sustainable realm (like Away luggage or Glossier products) because just like you, I want to know is the product really worth it or is it all marketing? Well the Slip Silk Pillowcase has been on my radar for awhile now. I mean who doesn't want to sleep on a pillow case that promises anti-aging?
So what do I think?
Ok so the claims are definitely a tad over-hyped (I mean c'mon there's no anti-aging anything really other than cosmetic surgery) but I will say that this silk pillowcase does have benefits and I haven't gone back to a regular pillow case since buying this one (coordinated bed sheets be damned, lol)! My favorite part about this silk pillowcase is that it prevents those sleep creases on my face, which as I get older take longer and longer to disappear (thanks to waning elasticity in my face). This is especially important to me since I'm a side sleeper and used to get those creases all the time. Before getting this I tried to become a back-sleeper since my friend told me side-sleepers get more wrinkles on their face from sleeping on it, lol. Nope, it didn't work so I'm so glad I got this pillow case instead.
The silk is a 22 momme weight made from Oeko-tex certified silk, which means harmful chemicals were not used for its production. That also means they use non-toxic dyes (I have the white one so there's minimal dyes in that one especially). I discussed momme weight before here. For reference, Everlane uses about 16mm silk while Elizabeth Suzann uses 23mm silk. Grana uses 22mm silk for their Georgette satin pieces (no longer readily available but you can still find it being used for their V-neck slip dress). And since I had a bunch of Grana credit left over, I thought I might as well try to make some silk pillowcases out of them (since it will mean they are essentially free for me). And well I made them and tried sleeping on it but it's not the same, even though the momme weight is the same. And that's because Slip uses a special charmeuse finish that makes it softer and more breathable when compared to the Georgette satin. So at least I know I'm really getting a great product from Slip that can't be easily copied.
Also they do mention in their FAQs that they "work closely with our suppliers to ensure that fair workplace practices are enforced and that only the highest quality materials are used." But they don't advertise where they make their products so I'm pretty sure they're made in China.
So yes, $79 is a lot for one pillowcase, but it's the only pillowcase you'll ever need for the rest of your life. Just take care of it well (I machine wash on delicate with the Laundress Delicate wash and hang dry). This product is definitely worth it for me and it's the tiny bit of luxury at the end of the night that makes sleeping just that much better!
P.S. If you're wondering if their Slip Silk Sleep Mask is worth it, I'm going to say that's a big fat nope. I loved the pillow case so much, I purchased the $50 sleep mask for travel and I have to say it's not comfortable. Either I have an abnormally large head or they make it way too small but it's tight around the head and puts pressure on the eyes. Save your money on this one and just skip the sleep mask.
