Bern helmet with a winter liner is the dogs nuts.
What makes you believe this, Bern helmets are rubbish imho
As someone who has suffered a head injury, if the OP does look at getting a new helmet they should look at the safety standards the helmet is certified by.
The most difficult certification to obtain is the cycling specific SNELL B90A standard which a lot of helmets including those made by Bern do not meet.
The only requirement to sell a helmet suitable for cycles in the UK is to pass the EN 1078 which is the same standard used to certify a helmet for use with roller skates.
The standard's key features of the EN 1078 test are
- Test anvils: Flat and kerbstone
- Drop apparatus: Guided free fall
- Impact velocity, energy or drop height flat anvil: 5.42–5.52 m/s
- Impact energy criteria: < 250g
- Roll-off test: Yes
- Retention system strength: Force applied dynamically. Helmet supported on headform.
The anvil tests are square on strikes which you are unlikely to come across in a cycling accident, it would also be fair to suggest imho that a cycle can travel at a faster constant speed than roller skates which also uses the EN 1078 to certify the helmets.
Bern Helmets are known for poor impact protection

the Brighton Thin Shell EPS from Bern came in well behind the seven other adult helmets in the test. The Nutcase model received a total score of 14 out of 100, while the Bern got a 13. These two helmets were the only ones in the test (which also looked at four youth helmets) to receive a "poor" rating in the "impact absorption" category.
