Light, easy, and endlessly wearable. The Cool-jams Women's DayBasics Long Sleeve T-Shirt Top is a soft, lightweight sleep top built for everyday comfort. This long-sleeve top pairs a scoop neck with a relaxed, non-cling fit that drapes beautifully. 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.

    size medium black jogger sets

    i have been trying to get size medium black joggers for months, and they have been out of stock. i wear cool jams exclusively as a person who is disabled, but still enjoys fashionable loungewear. When can i expect to order them?

    i love your cool jams.

    thank you.

    Love the softness of these pjs. This was my 5th set. They come in pretty colors. My only complaint is that this set is a bit smaller than the others. I like the roomier fit better.

    Great fit and feel

    Fabric feels nice and washes well, and sleeves are the perfect length.

    Love the fabric. Wish you'd ditch the drawstring at the waist.

    Drawstring at waist is much too bulky. Please make the bottoms with the option of requesting with an elastic waist, like some I have that were purchased a long time ago. The drawstring is simply too bulky.
