I’ve seen it used under hard hats in -5°C conditions, and it holds up—warm, snug, and no faff. For around £11–£16, it’s a smart grab for anyone who wants a helmet-safe thermal layer that won’t mess with fit or safety.

Bought because most building site will ONLY allow one of these to be worn under your hard hat. That is, after all, what they are for. Very good fit, cover my ears and keep head warm. When not is use, folds up very small for storage in toolbox or van etc. Quality of the product is very good and feels like it will last several winters. Very good product, fits well, keeps head/ears warm - does what it say on the tin. Competitive price too.

Very good, keeps you warm

Brilliant

Ordered this due to the cold weather recently - should have got it well before now. I normally wore just a normal beanie hat under my hard hat, but this does make a bit of a difference. Its not as bulky and the hard hat sits okay with it on. Kept my head nice and warm whilst working out on a hospital roof in -5 weather.

This helmet liner is worth having for any one who wants to keep their scalp/head warm when wearing a helmet in a cold environment. It is also health and safety complaint when worn under a helmet.

Perfect helmet liner Covers ears and head fits well under normal hard hat Good fit in medium size head

perfect fit, material is very comfortable and quality

Comodo w ripara dal freddo . Peccato mi pare dia misura unica

L'articolo nel titolo indica 10 pezzi, ovviamente è solo 1. Presa la taglia più grande, non arriva a coprire le orecchie neanche a metà come da foto e non sono un gigante. Qualità scadente in generale, quasi per nulla elastico. Non me lo aspettavo da JSP, con i caschetti mi trovo molto bene.

Je trouve que pour une taille L-XL il fait vraiment petit … sinon fin et chaud, confortable avec le casque de sécurité !
