Longtime Berkshire Buyers 🩶
Color: Stormy Weather, Size: King (90 in x 108 in)
We have been Berkshire buyers for years and they never disappoint with their quality. They always make the best bedding on the market at a reasonable price point. In the economy we currently live in, it's getting harder to find quality products that don't break the bank & Berkshire has been consistent for years!
This blanket is no different & has held up to their name and brand. This blanket is large, which I love. There's nothing more annoying than trying to cover your whole body with a 50x60 sized blanket lol. This blanket is most definitely aesthetically pleasing but also keeps us warm. It feels like this blanket traps our own body heat and keeps it contained instead of producing heat, making us hot. We always stay a nice, consistent temp without getting overheated and sweaty....nobody wants that lol. It's made from high-quality fabric that isn't only soft and comfy but it's woven tightly and has held up wonderfully for how much we use it! This blankey also washes really well ((i.e. zero shrinkage, dries in an adequate time, no color fading and/or bleeding)). I also appreciate that even though this blanket keeps us warm, it isn't heavy & pretty lightweight compared to some of our other non Berkshire blankets. The color is also a rich blueish, cool colored gray that accentuates all of our decor and other bedding.
Overall, Berkshire has always been a household name in ours. We love the quality, the consistency of knowing what we're getting when we purchase from their brand, and the prices are always crazy reasonable without sacrificing what you receive. Hands down another great item from their brand & we will always recommend ✔️

Soft, plush, lovely
Color: Blue Moment, Size: King (90 in x 108 in)
We got this blanket in king size to use in lieu of a comforter in the warmer months. It's incredibly soft and luxurious. It's thick enough to feel plush and heavy, but thin enough to be perfect for a cool summer night.
It feels like really excellent quality, too. This is not cheap thin fleece. I've only washed it once so far, but it seems like it'll hold up to many washes. It's big, though, at least in king size. It takes up pretty much our entire washing machine, so it needs to be washed by itself or with little else. To dry, I tossed it in the dryer for 40 minutes or so on medium heat and then hung it over a banister to finish drying, and this seemed to work well.
It's also a very pretty blue, like a dusky light blue, just lovely. Overall, I'm very happy with this blanket.

A good lightweight blanket
Color: Blue Moment, Size: Twin (60 in x 90 in), Color: Blue Moment, Size: Twin (60 in x 90 in)
With perpetually dry hands I have issues with certain fabric textures. This Velvetloft blanket is on the border of triggering, but nothing like how the Classic Extra-Fluffy Plush throw is. The ribbing is interesting visually, but also made the blanket feel a lot lighter too. Definitely one I'll keep on the couch for a chilly day and not for my bed.
When I washed it I was expecting a lot of shedding like the Classic one, but there wasn't as much. I washed it on cold and dried it on the delicate setting since I don't have a good place to air dry. It doesn't appear any worse off than before I washed it.
Overall I like this one way more than the Classic, but the Primalush wearable blanket is still my favorite.

Wait until you unroll this beautifully soft blanket! It’s the one you want.
Color: Goose Egg, Size: Twin (60 in x 90 in), Color: Goose Egg, Size: Twin (60 in x 90 in)
I can’t pass up a good blanket, and boy is this one impressive! It’s another high-quality product from Berkshire Home Company.
What I love about my goose-egg colored, velvety soft, blanket is the ribbed design. The lines separate the elevated design, and I could literally rub my hand over it throughout an entire movie!
It’s SO plush and soft. It’s made from their signature VelvetLoft fabric. Plus the design makes it look like a planned piece of your decor. I like the color I chose but there are others to choose from as well.
It’s nice and thick but not too warm. I got the 60”x90” twin size which is great for me! Next time I will get a queen size to go over my bed.
The price point is so low for the quality you get! You should stop your search now because this is the best one!

Luxurious VelvetLoft From Berkshire
Color: Stormy Weather, Size: Full/Queen (90 in x 90 in)
Berkshire hits it out of the park with yet another fabulously lux blanket. Their VelvetLoft is my favorite for warmth and softness all while looking like an offering at a high end hotel or B&B.
The medium weight was the perfect choice to pair with the large ribbing and while this IS the blanket to choose once the leaves start to fall, it's almost sinful to snuggle up with to watch a movie with the AC humming in the warmer months since it washes like a dream and did not shed at all.
I used cold, delicate and my favorite scented delicate wash. Dryer on Medium for 10 minutes and then Low for anther 20 minutes. Perfect!
The Stormy Weather is a silvery gray neutral and will work with multiple coverlets, bedspreads and quilts.
Perfect gift! Definitelythe blanket you want in the guest room!.
