Men's bathrobe in terry cloth, polar robe, fleece or satin, with shawl or kimono collar, knee length or mid-calf: two different pieces depending on whether you're stepping out of the shower or looking to stay warm.
A men's bathrobe in towelling is used to dry off after a shower. A men's dressing gown, made from fleece, terry cloth or satin, doesn't absorb and is meant to keep you warm at home. Both cross over at the front and tie at the waist, but they're not bought for the same reason, which is the most common confusion.
This is the clearest visual difference between the two styles, and it has practical consequences. The shawl collar, rounded and folded, covers the neck and is warmer: it's the classic collar of the men's towelling bathrobe. The kimono collar, straight and without a flap, exposes the neck, dries faster and gives a lighter look, often preferred for satin dressing gowns. On a winter bathrobe, the shawl collar is definitely more comfortable.
Knee-length is the most common: it dries quickly, is easy to put on and doesn't get in the way on stairs. Midi-length keeps you much warmer and is suitable for cooler interiors, but can be bulky and takes longer to dry. For strictly bathroom use, knee-length is sufficient; for a winter dressing gown worn in the evening, the extra length makes a real difference.
It's one of the most common gifts, and this shapes part of the offering. Many men's bathrobes can be personalised with embroidered initials or a name on the chest, which takes a few days and makes the item non-returnable: check the size before ordering. To give a gift without knowing the exact size, models in adjustable one-size fits all with a belt, or sizes L and XL that cover most body types, limit the risk of error. The bathrobe is rarely worn alone: men's pyjamas in flannel or cotton complete the indoor outfit for the cold season.
