Best Sun Hats for Summer 2025 Reviewed

With temperatures soaring, finding the perfect sun hat is essential for staying cool and stylish. After testing several options, here are three top contenders: the Seasalt Castle Point Sun Hat, the Mountain Warehouse Wide Brim Packable Sun Hat, and the CoolBits Ice Pocket Hat.

Seasalt Castle Point Sun Hat: Retro Style and Comfort

Seasalt offers a wide selection of sun hats, with the Castle Point Sun Hat standing out at £29.95. Made from woven paper that mimics straw, this hat features a retro, short-brimmed design reminiscent of a bucket hat. It comes in three colours: natural cypress, cacao, and mabel multi. The internal ribbon allows for easy size adjustment, providing a secure fit. One shopper praised its versatility, saying: "Can wear it with a dress or with trousers or shorts. In other words you can dress it up or down. Packs easily which is a great bonus when travelling. Fitted perfectly, so no fear of it getting blown off on a windy day, like some hats." The hat holds an overall rating of 4.6 stars from Seasalt customers.

Mountain Warehouse Wide Brim Packable Sun Hat: Budget-Friendly Beach Essential

For a more traditional beach look, the Mountain Warehouse Wide Brim Womens Packable Sun Hat is an excellent choice. Usually £16.99, it is currently on sale for £9.99 in brown or £6.99 in light beige. Made from paper-straw with a moisture-wicking sweatband, it is lightweight and breathable. The wide, floppy brim provides ample shade, and the hat is designed to retain its shape even after packing. Rated 4.4 stars by shoppers, one reviewer noted: "Just what I needed, a relaxed fit and good shade over my eyes too. Folds into a bag easily without changing shape." While some found it a bit too floppy, that very quality makes it perfect for a relaxed beach vibe.

CoolBits Ice Pocket Hat: Ultimate Cooling for Outdoor Activities

For those seeking serious cooling, the CoolBits Ice Pocket Hat at £41.29 on Amazon is a game-changer. Popular in Japan and the US, this breathable polyester hat features a removable flap with pockets for ice cubes or crushed ice. It harnesses evaporation to provide a cooling sensation for up to three hours, while protecting against harmful UV rays. The hat includes side mesh inserts, a chin strap, and an adjustable wired brim. One user reported: "I've been using this for a couple of days now, and it really does help keep me cool! It has not dripped or leaked. The ice seems to evaporate. I've tried the high end neck coolers, but this works better for a fraction of the price." Available in khaki or beige.
