More about the V-Neck Nightshirt
The Cool-jams NightCool V-Neck Nightshirt is a knee-skimming cooling nightshirt with an open V neckline that leaves the throat and upper chest uncovered, which is what many women want on hot flash nights. The body is cut from temperature-regulating Kottinu fabric that wicks sweat off the skin and dries in minutes, and an odor-control finish helps the fabric stay fresher between washes. It is relaxed through the body with short sleeves, so nothing pulls when you turn over. In Black, Navy and Merlot, in sizes S to 3X.
Is a V-neck better for hot flashes?
An open V neckline leaves more of the throat and chest uncovered than a high or closed neck, which is why many women who sleep hot choose this style.
Is this a nightshirt or a sleep shirt?
Both names describe the same garment: a knee-length shirt worn on its own to sleep in. You will see it listed as a women's sleep shirt and as a nightshirt.
How does the fabric handle sweat?
Kottinu is a performance sleep knit. It pulls perspiration off the skin as it forms and dries in minutes, instead of holding it against you the way cotton does.

What is Kottinu?
Kottinu, a technical synthetic (engineered polyester microfiber) made for firefighter base layers and medical scrubs, now crafted for hot sleepers and night sweats needing moisture-wicking and cooling pajamas. Soft and smooth with a cotton-like feel, it pulls sweat off your skin, dries in minutes, carrying body heat away with it.
A Bact-Out finish helps the fabric resist odor, so it stays fresher between washes. Kottinu resists pilling, holds its shape, and machine washes easily.
