Need advice for winter gear suitable for outside sweet spot workouts

I live in Bulgaria, practically market is very small and mostly filled with expensive /never on sale gear/ or unknown brands. I like decathlon and found some Really good gear from them. Mainly I order from Tradeinn.com from surprise…. Spain lol…just for 10€ by posts. Got my Power meter on sale from them, hiking gear, running gear and casual clothes. I would probably get some gear from decathlon.
