Enfin un chapeau anti-UV qui coche toutes les cases

Je l’ai porté à la rivière et dans mon jardin, en pleine Guadeloupe, même à midi, et franchement : je valide à 100 %.
J’ai les cheveux très bouclés et volumineux, et il me va parfaitement sans m’écraser la tête. Il est léger, ne fait pas transpirer, et surtout : je ne plisse plus les yeux même sans lunettes de soleil.
J’ai choisi ce modèle pour son bord large et sa couleur nude intemporelle — il protège bien et va avec tout.
C’est le chapeau parfait si tu veux profiter du soleil sans avoir à remettre de la crème toutes les deux heures. En plus, il se plie facilement et rentre dans le sac de plage. Bref, je recommande à toutes celles qui veulent une vraie protection sans sacrifier le style.

J'ai pris la plus petite taille et il est beaucoup trop grand pour moi. Il ne tient pas. Sinon l'article est conforme à la description et de bonne qualité.

Das Modell scheint praktisch, weil es zusammengelegt in Koffer oder Rucksack passt. Es sollte durch seinen breiten Rand besonders gut vor Sonne schützen. Bin froh diesen Hut gefunden zu haben, weil er mir ermöglicht, meinen Urlaub auch in sonnigeren Gegenden entspannt zu genießen.
