Super soft blanket
Color: Polar Blue, Size: Full/Queen (90 in x 90 in), Color: Polar Blue, Size: Full/Queen (90 in x 90 in)
It turned out nicer than I expected, what a surprise. Very light and soft, slightly stretchy. It felt high quality and the color complimented the room perfectly. My mom even wanted to take it to the paint store and find out what color it is so she can paint her room the same color. Great blanket.

Nice blanket
Color: Southern Blues, Size: Full/Queen (90 in x 90 in), Color: Southern Blues, Size: Full/Queen (90 in x 90 in)
This is a really nice blanket. If fits on my bed very well. It went through the laundry really nice and didn’t fade or ripper. Have any strings come undone. I like the very light green color. My pictures aren’t great, but one side is the underneath side, the white and then the light green is the other picture. This is well-made you can see in the picture up close that it’s so really well. All layers are sewn together, so you do not have bunching up when you wash the blanket. It is super soft with a good weight. It’s not super lightweight, but it’s not heavy at all. Overall, I’m very pleased with it and I would recommend.

Soft, Lightweight, and Perfect for Year-Round Comfort
Color: Polar Blue, Size: King (90 in x 108 in)
This Berkshire 3-layer fleece blanket is exactly what I was hoping for. It is incredibly soft and has a cozy cotton-like feel without being too heavy or bulky. The king size is generous and fits the bed nicely, but it is also comfortable enough to use on the couch.
I really like that it feels warm and breathable at the same time, so it works well for different seasons. The Polar Blue color is soft and pretty, and the blanket has a nice textured look that makes it feel a little more elevated than a basic fleece blanket.
It also washes well, which is a huge plus. After washing, it still feels soft and comfortable, and it did not lose its shape. Overall, this is a great blanket if you want something cozy, lightweight, and easy to care for. I would definitely recommend it.

I love this because it folds up easily & does not take up much space but keeps you warm and secure.
Color: Southern Blues, Size: King (90 in x 108 in)
Heavy and BIG. The color is great. Its not very thick but it does have some heft to it. I love this because it folds up easily and does not take up much space but keeps you warm and secure. Its got a waffle type contour texture. It says its fleece but to me it did not feel like fleece. However, I have never heard of berkshire fleece before-- I would not guess this is fleece at all. Its not fuzzy in the least. It is breathable and the color is muted and perfect. For a king sized blanket this is surprisingly portable yet substantial enough to keep the entire bed covered and warm!

Thin, summer weight throw, quality could be better
Color: Southern Blues, Size: Throw (50 in x 60 in), Color: Southern Blues, Size: Throw (50 in x 60 in)
This is a very light weight blanket and the "fleece" is no where to be seen. The blanket looks like cotton but has a very synthetic feel to it. Three layers implies some weight but it is thin.
The construction is sloppy, see images, where the stitching looks slap dash to the point where it cannot be reversed.
I liked the color, the blue is a little on the aqua side but it is a very nice calming hue. The stitching is quilt like and nicely done.
I noticed other reviews felt like it was a medium weight but the only time I would use this would be to use as a cover if the AC went out. To me, the blanket is decorative and not particularly useful.
