After Mr Tilley passed his kids tried to run it. They sold the business some time ago.
You can find deals on his winter hats. It would be a good idea to buy one
I bought a summer hat. A blue one. I paid quite a bit. Impulse buy. I have two winter hats. A third one might be too extravagant.
Mr Tilley used to wait on customers in the store. I respected him
Today brought snow and sleet so with a warm hat on, zero issues despite outdoor temperatures being on freezing. For cycling, I can see a new ‘Belgian’ cap being bought.
I’m very taken with the Tilley winter hat - nice design.
Lithium Ion batteries are greatly affected by cold. Since you mention that it occurs only in your left aid I suggest you have that battery replaced.
Thanks for your post.
I had issues with setup rechargeable battery life from day one. Paradise P90Rs I asked if my hearing aids were could be checked. The Audi said they were ok.
I had changed service providers after a year and a half. At the end of warranty my new service provider sent my Paradise ha in and they were replaced, and a new charger provided.
The new HA battery life is better for regular days.
My worst experience was a 24 hour hospital stay for a procedure with my cardiologist. Batteries didn’t last. I couldn’t hear.
I’ve had no issues with cold weather use.
One wonders if an alternative to Lithium Ion batteries will come along for rechargeable HAs. I always wondered about kinetic energy, as in automatic watches, but I guess power optimisation would need a quantum leap and you still need to store power in the HAs.
Back on topic - both HAs had the batteries ‘replaced’ (I.e Sonova gave me new HAs) in May 24. Solution seems to be…wear a hat…
They will have to remove my Phonak Naida with nonrechargable 675 batteries from my cold dead ears. Two weeks in rain, sleet or snow. Not sure what to do if some crazy government mandate takes away the batteries. They are trying that with LED light bulbs and I will have to replace a few thousand dollars worth of dimmers. ARGHH.
Huh! I walked the other night for 2 hours - it was -18 C with the wind chill. I wore a big down coat and had the hood pulled tight over my head. My face froze, my hands froze, my feet froze, but my rechargeable hearing aids went on ticking.
They wouldn’t have been ticking for very long if they had been exposed to those subzero temperatures @Jody, could you hear clearly with them under your hood/hat? That was always my problem, I usually wear a Trapper’s Hat when out in the extreme cold, it’s fine if I’m on my own, but talking to folks, I will struggle… Cheers Kev 
Yes @kevels55, I was walking with a friend, so we chatted the whole time. I could hear with my hood up, even though I had used my scarf to pull it tight around my head. We were also walking with purpose, so we generated a fair amount of body heat, even at those temps.
I do remember, though, that my previous cellphone would die in my pocket while I was out for an hour’s walk in the cold. My current one doesn’t do that. Perhaps a newer battery makes the difference?
Yeah @Jody, I will struggle with my Trapper hat down, although I struggle, with it up 
but it’s obviously worse for hearing, if it’s down… My main problem, when I had rechargeable aids, was my job, I worked with Criminal Justice, as a supervisor, I took the bad boys and girls, whom had been sentenced by the courts, out to do work in the community, on my own, with usually 5 offenders, some were violent, but mostly violent to other offenders, so I had to keep my wits about me, at all times, so, I couldn’t wear a hat… Well not one that covered my ears! Twice, my aids cut out in adversely cold weather, on both occasions the temperature was about -8 to -10 C, they will not reboot until placed back in the charger… So Phonak replaced them, when I explained my situation, for the replaceable battery version… Problem solved. Nowadays, I am fortunate enough to be retired, stress levels have reduced tenfold, but, I believe that job, did have a lasting effect on my on my overall mental health! But, we all have degrees in hindsight… Cheers Kev
