More about the Long Tank Gown
The Cool-jams NightCool Long Tank Gown is a long cooling nightgown for menopausal night sweats and for anyone who wants more coverage without more heat. The breathable Kottinu knit wicks perspiration off the skin and dries fast, and an odor-control finish helps the fabric stay fresher between washes. The sleeveless tank cut keeps fabric off the arms and shoulders, and the longer, straight skirt hangs rather than winding around you as you move. In Black, Navy and Merlot, in sizes S to 3X.
How long is this nightgown?
It is a full-length gown, the longest in the NightCool range and noticeably longer than the knee-length Gathered Tank Nightgown in the same fabric.
Is a long nightgown too warm for night sweats?
Not in this fabric. Length adds coverage, not heat, because Kottinu is a temperature-regulating knit that moves moisture and keeps air flowing.
Does it have a built-in bra?
No, this style has no built-in support. It is cut as a straight sleeveless gown.

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 fast, 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.
