A Smurf hat is a piece of clothing generally worn by all Smurfs. It is a standard woolen cap with the top part of it flopping forward (or in any preferred direction, as with Slouchy's hat), basically resembling a Phrygian cap. Male Smurfs generally wear Smurf hats because the top of their heads are bald. Female Smurfs tend to wear them simply to identify themselves as Smurfs. Most Smurfs wear white hats while Papa Smurf wears red, Grandpa Smurf wears yellow, and Sweepy Smurf wears black. While in the cartoons and the comic books Tailor Smurf is the one who makes Smurf hats, Papa Smurf is the one who makes them as Christmas presents every year in The Smurfs: A Christmas Carol, with each Smurf hat tailored specifically for its recipient.
Smurf hats may also vary in appearance depending on the type of Smurf wearing it. Greedy, Chef, and Baker who are the village chefs, wear a Smurf hat that is a variation of a chef's hat. Farmer in the comic books and Nat in the 1980s cartoon show wears a straw hat in the form of a Smurf hat, and Wild wears a Smurf hat made of leaves.
In both the cartoons and the comics, Smurfs are seldom seen without their hats, but there are some memorable occasions, such as the episode in which Greedy has been ordered to take a diet. After Greedy's house has been stripped from everything edible, Papa Smurf points at Greedy's hat. Greedy takes it off to reveal a cake he had hidden there.
In the shown picture from The Smurfs And The Magic Flute, one of the Smurfs doffs his hat to a nest of birds after they have successfully transferred the nest from the tree they were going to cut down for making the second magic flute onto another tree.
In the comics it's in "The Black Smurfs" that we see what a Smurf without a hat looks like. After Papa Smurf's lab explodes, we see him lying amongst the rubble going "Gnap?" because of confusion of what just happened; his hat, which was blown from his head, is seen falling down along with some debris. In another comic book story, Papa Smurf goes swimming without wearing a hat.
In the 2011 Smurfs movie, the Smurfs use their hats as parachutes to slow their descent when leaping from the window of the Winslows' apartment building in New York City to a nearby taxicab. The Winslow child Blue wears a hospital cap in a manner similar to a Smurf hat.
In The Smurfs: A Christmas Carol, while Grouchy is being visited by the Three Smurfs Of Christmas, it is revealed that Papa Smurf tailors every Smurf hat that he gives to his little Smurfs every Christmas, making them specifically for each and every Smurf. Grouchy, who was expecting to get a hang glider, was constantly disappointed in that the only gift he got was a Smurf hat, and after Jokey's prank where he was fooled into believing Papa Smurf finally came through with a hang glider, only to have another of Jokey's "surprise" pranks pulled on him, he refused to have any further participation in Christmas. It was after the visitation by the Smurf Of Christmas Future, when Grouchy realized that the greatest Christmas present he had was that of family, he gladly received his current Christmas present of a Smurf hat and discovered that he could use it to glide his way through the air.
Smurf hats are sold as real-world products for those who want to dress themselves up as Smurfs for Halloween or costume parties. On Global Smurfs Day, people in various cities around the world gathered to show their love for the Smurfs by dressing themselves in the manner of Smurfs, wearing blue shirts, white pants, and white Smurf hats with their faces all painted blue.
