WTF is “CoolMax”?
Coolmax is the brand name for a series of polyester fabrics developed and marketed by The Lycra Company (formerly Dupont Textiles and Interiors then Invista).
Coolmax is marketed as “moisture-wicking” and “breathable”. As a polyester, it absorbs little fluid and dries relatively quickly (vs cotton). The cross-section is non-round, increasing surface area by an estimated 20% (over round fibers) in order to produce a wicking effect via capillary action.
Like other polyester fabrics, Coolmax is flammable and has a relatively low melting point (~255 °C), giving clothes made from it a tendency to melt and fuse to the wearer’s skin when exposed to high heat. This has led to Coolmax and other polyesters (along with acrylic and rayon) being restricted or banned in certain high-fire-risk applications, such as firefighting and front-line combat.
@mike808 CoolMax is the fabric in all those wrinkle free, loose-draping high end t-shirts. And yes, they are REALLY comfy and cool in the heat.
BTW I was a FF and we banned all polyester stuff from our fire gear in the 90s. Still, 255°C is 490F, so unless you are FIGHTING a fire, this is not a concern. If your house has a fire, you will succumb to smoke inhalation LONG before your bedroom reaches 500F and your sheets melt. No worries.
Meh can’t seem to get the numerous hints every time they offer plastic sheets. Seems 100% cotton is preferable to the majority of commenters. Why not offer? I purchased cotton at this price point a few years ago, still quite happy.
I can’t stand polyester, rayon or anything MICROFIBER! I bought 100% COTTON Sheet set from meh. com
& they are great! Microfiber makes me hot & sweaty… like Schweddy balls SNL!
I tend to pee a lot. Will these save me from wearing those chafing rubber underpants? I mean, at night?
I do love to feel the crinkle crinkle during the day…

Remember when Kathy Ireland was the poster to have on your wall? Ah the 90’s…
@ExtraMedium No.
@ExtraMedium Who could forget her movie “Alien from L.A.”
She has phenomenal eyes!

@haydesigner, not her, but I’m totally leaving that gif
Cool-Whick
@Num1Zero slow clap
Holy sheet!
Oh well, no
cal kingcotton again…More petroleum by-product bedding.
So even if you feel cooler in them, they’re contributing to warmer temperatures overall.

@mike808 CoolMax used to be my rap name, but I was making copies the other day and got an idea for a new name. Now I’m “Toner Low”.

I like cool bedding, or is that bedding cool?

“80% Microfiber/20% CoolMax” …uh so 80% PolyesterSmallFiberyHooseyWhatsit and 20% PolyesterOtherBrandyStuff… so… uh… 100% schweatyester.
Don’t want Cool Max in the sack with me ever !
Not feeling it with cool/comfortable claim, more likely
@robson I wish they’d bring that flavor back. Name aside, it was actually really good.
Ordered sheets but I think I’m getting dinner…

Cool or microfiber. Pick one. The two are mutually exclusive.

Community: “Would love some cotton sheets.”
Meh: “That’s a weird way to spell polyester.”

@Bumplepimp You forgot to add “(Asking for a friend.)”
I-Sheet M’Drurz
Cool sheets you say? Microfiber you say?
Deception! Meh!
Give me 100% cotton percale or give me nothing!
Actually, I have a couple of sets of microfiber sheets, and they are very comfortable!
That said, no love for us California King people?!?
When people review an item they didn’t buy Meh should step in. Above their fake review should say “The following post is stupid.”
Got mine today and they seem great! Two shipments from meh arrived in a few days and on Sunday!
