Goede pet

Goede pasvorm! Ik gebruik het ook op de fiets, maar door de wind gaan zijkleppen omhoog. Heb er zelf aan beide zijden glittenband aan bevestigd zodat ik het vast kan zetten onder de kin. Misschien een idee voor een volgend model!

Te weinig comfort

Ik had het hoofd van mijn man opgemeten en deze pet besteld. Bij het dragen is gebleken dat hij vindt dat het te krap zit en er hoofdpijn van krijgt. Helaas, voor hen geen succes.

Buongiorno, io ho i capelli molto lunghi e quando ho caldo non riesco a tenerli sotto il cappello sciolti, stavo cercando un cappello con la fessura per far uscire la coda di cavallo. Potete aiutarmi?

Ker Sun

Buongiorno!

Grazie per questo nuovo messaggio. Capisco perfettamente il problema: con il caldo, poter legare i capelli è fondamentale per stare freschi e comodi!

Al momento non abbiamo ancora un vero e proprio cappello con la fessura per la coda di cavallo nella nostra collezione. Tuttavia, le consigliamo vivamente di dare un'occhiata al nostro modello Saint Malo Casquette.
Anche se si tratta di un cappellino (stile visiera) e non di un cappello classico, è perfetto per essere indossato con la coda di cavallo. Inoltre, è dotato di una visiera/tesa molto ampia che garantisce un'ottima ombra per proteggere al meglio tutto il viso.

Speriamo che questa soluzione possa fare al caso suo! Restiamo a completa disposizione per qualsiasi altra domanda e le auguriamo una splendida giornata. ✨

Cordiali saluti,

Team Ker Sun

Buongiorno, il mio compagno ha la testa che misura 61, e i capelli ricci. Cercavamo un cappello un po' più largo. Ma anche se segnate che avete la taglia XL poi nel sito non trovo niente. Potete aiut

Ker Sun

Buongiorno!

Grazie mille per il vostro messaggio. È un piacere aiutarvi a trovare il cappello ideale per il suo compagno! Con una misura di 61 cm e i capelli ricci, avete perfettamente ragione: serve un modello comodo che non stringa.

Abbiamo ottime opzioni disponibili in taglie grandi che fanno proprio al caso vostro. Ecco i modelli che vi consigliamo di cercare sul nostro sito, in quanto sono disponibili in taglia XXL:

- Il cappello Augusta
- Il cappello Oasis
- Il cappello Sequoia
- Il cappellino con visiera Sequoia Cap
- Il cappello da pescatore Faro bucket hat

Inoltre, vi consigliamo vivamente di dare un'occhiata anche al modello Gavroche nella taglia L/XL.

Speriamo che tra questi possiate trovare il modello perfetto per lui. Se avete difficoltà a trovarli sul sito o se avete altre domande, siamo qui per aiutarvi.

Vi auguriamo una splendida giornata! ✨

Cordiali saluti,
