Just ordered a Gamma II head torch from Alpkit. Seems to be good value at £21.00. The only slight disadvantage is that it doesn't take rechargeable batteries but I don't think that will be a problem.
Just bought:Anker 10,000mah battery pack + USB C cableQuechua Escape 20 backpackOn the look out for a good scarf/face mask/neckwarmer combo!
Take a look at the Buff range.
