Reddit mentions of Mountain Hardwear Dome Perignon Hat

It really depends on what you are doing. You say "Not planning on doing any super athletic or intensive activities"... does that mean mostly running from the house to the car, or walking from the car to the shopping mall? Out walking the dog? Or spending 3+ hours watching a football game outdoors?

If it's near freezing, I'll generally wear a heavy softshell and mid weight fleece (and good hat). Below that I'll switch to a hard shell and fleece. This is generally fine as long as I'm moving around... if I'm standing still waiting to get in line for a show, they can be too cold.

If I expect to be out for more than 15 minutes, if there's a big wind chill, I'll throw on a long sleeved thermal shirt and maybe add another light layer. Again, good if I'm walking around.

I have a cheap TNF Nuptse 700 fill down jacket that I wear if it's really cold, if I'm making a quick trip to the store and don't want to bother layering, if I expect to be out sitting in the cold for any length of time, or going to a friend's house who has his thermostat set to 80F and I don't want to have to strip off all the layers when I get there. I don't worry about down getting wet since I only break it out when it's well below freezing. When I'm sitting around at a sporting event, I'll add a fleece, a blanket, a pad to sit on, a thermos of hot drinks (and a Jetboil nearby so I can make more if necessary).

I generally don't wear thermal pants, just jeans. But I do have some cheap snow shell that will slip over the jeans, they don't insulate much but cut the wind which is generally all I need.

Boots... my hiking boots are great in the mountains, but not so much walking the streets around town. Good pair of Sorel Pac boots and wool socks make a huge difference. If I'm at a game sitting around, I'll not above using some toe warmers.

Good windstopper fleece hat like the Mountain Hardware Dome Perignon , gloves, scarf or neck gaiter.

I picked up many of these items at TJMaxx/Marshalls. Stocks are hit or miss, but I've bought a few nice hard shells, down jackets, hats and gloves, thermals, wool socks. I've picked up softshells and other gear at Sierra Trading Post (make sure you sign up for the email and get your discount code, free shipping + 25% off all purchases is generally a good deal but sometimes you get bigger discounts).

Good luck!

PS - I've linked to items on Amazon just so you can see what they look like, but you can often find them elsewhere for cheaper.
