In auto mode, each unit provides air for your home at your desired comfort level. Set your desired temperature, and the HVAC unit will determine how much heat or air conditioning is needed.

Super soft
Size: Small, Color: Light Blue/White, Size: Small, Color: Light Blue/White
Perfect fit! Bought as part of a set for a bachelorette trip and they are so comfy. Look exactly like the listing photos. Wore them through a Pilates class and a day of errands with no issues. Love the baby blue color with white contrast binding. Perfect stretch, fabric squat proof (thick enough nothing shows when you bend) and very durable.

Soft, fit, and love the color
Size: XX-Large, Color: Slate Grey/White
I love how soft these are and the grayish-violet color. They seem well made and wash well- especially for the price. You can’t see through them. They are mid weight so they keep you warm enough for air conditioning and Florida cold. Probably not snow worthy or wind strength though. They are true to size if you want them to fit but not cling or act like leggings. They have just enough room. I bought the matching jacket but I’m more thrilled with just the pants. The jacket fits as it should but not over my too many milkshakes stomach.

Happy with purchase
Size: Medium, Color: Flamingo Pink/White, Size: Medium, Color: Flamingo Pink/White
Acceptable product. Good fit and fabric feels nice. A little see through if you squat and have on dark or patterned under pants but if you wear undies that are your skin color, there’s no issue at all. I wish they came in a length that was just past the calf. These are a little long to be on my top go to legging for yoga. Minus one star due to lack of length options.

Well made and comfortable
Size: Small, Color: Slate Grey/White, Size: Small, Color: Slate Grey/White
Very cute and comfortable workout set! I bought the leggings and the matching sports bra sold separately. I am 5'4" , 125 lbs and bought a small in each. The leggings are tight but not too tight, doesn't dig in and doesn't roll down. Well made and thick material. Worked great for a very sweaty hot yoga class. I'll be buying more in different colors.

Fall or Winter
Size: Large, Color: Black/White
For me, these leggings are a perfect fit and perfect for Fall & Winter, maybe early Spring. Summer though, I would not dare. Comfort wise, the leggings are soft and perfect for the gym, grocery shopping, lounging, even sleep. I passed out in mine and slept just fine.
