Light, easy, and endlessly wearable. The Cool-jams Women's DayBasics Long Tank Gown is a soft, lightweight nightgown built for everyday comfort. This sleeveless tank gown has a relaxed, non-cling, shin-length silhouette and comes in beautiful prints. It is made from our DayBasics fabric, which feels gentle and airy against the skin, the kind of soft that gets better the more you wear it.

Part of the Cool-jams DayBasics collection of soft everyday sleepwear for women.

More about the Long Tank Gown

The Cool-jams DayBasics Long Tank Gown is the full-length version of our tank nightgown, cut for complete coverage down the leg. The wide tank straps sit flat on the shoulder, and the straight cut through the body means the gown hangs and stays put rather than winding around you as you move. It is made from soft, lightweight DayBasics fabric, gentle against the skin and easy to wash and wear, and the wide straps mean it stays put without adjusting. Full length, in ten colors, in sizes S to 3X.

How long is this gown?

It is a full-length gown, cut noticeably longer than our mid-thigh Gathered Tank Nightgown.

Is a long nightgown warmer?

It covers more of the leg, so it feels more covered, but the DayBasics fabric itself is lightweight and breathable rather than heavy.

Does it have a shelf bra?

No. If you want built-in support, the DayBasics Long Racerback Tank Gown has a shelf bra sewn in.

    The return of the great long tank gowns!

    The material is just like it used to be, sleek and cooling. The scoop neck is actually a scoop again with nice roomy armholes. Thank you, Cool-jams for returning to your roots.

    Thank you for this, Ronni 💙 You noticed exactly the things we care about, the hand of the knit and the neckline. Everything sold as NightCool now is the original cooling fabric, so what you have is the real thing. Roots is the right word for it. Thank you for coming back ✨

    Love the night gown

    comfy and supportive, which I like when sleeping too. Thought the supportive cups with a bit of padding would make me look too bodacious for 77 years, but perfect and great to keep cool at night.
