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.

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.

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

Is okay but the material is too thin it needs to be more thick

perfect fit, material is very comfortable and quality

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 fit under helmet great quality and folds up really small if not required so you can carry it around without taking loads of space in your pockets

Good 👍
