Care Instructions
Follow these easy instructions for washing your fleece sheets and you'll enjoy years of cozy softness.

For best results, wash your sheets separately from other laundry in cold water using your regular detergent. If extra cleaning power is needed, you can use non-chlorine bleach without worry.

The washing machine's spin cycle usually does a great job of getting all of the excess water out of the sheets. You can tumble dry them on a low heat setting. Or go old school and hang them up to air dry--they should be ready in no time!

Avoid high heat and excessive agitation to keep your sheets soft and pill free.

What does that mean? Simply put - make sure you don't overload the washer or dryer (washing them separately really is best), use the gentle cycle, and don't use high heat in the washer or dryer. And definitely don't iron them!

Rated 5 out of 5 by from The BEST fleece sheets! I use Berkshire fleece sheets all winter on my bed. I have a set of another brand, but they are not close to the quality of the Berkshires. I bought a set to send as a present to my daughter. She said "They are like sleeping on velvet sheep or baby bunnies. We love them." They have a generous fit for our deep mattress plus topper and much thicker fleece. We have used ours for about 4 years and they are still going strong. Last spring I told my husband it was his last night in the cuddly sheets since the weather was too warm and he starting yelling "NO, no, no." Only drawback is they make it very hard to leave the bed.

Rated 5 out of 5 by from last forever I have purchased at least 3 different set of the polarfleece sheets. The heavy ones and the lighter ones for summer. I can't say enough about these sheets. They last forever... They have all been washed more times than I can count.. and get better with each wash!!The set on my bed is at least 5 years old..These are the best, long lasting sheets, ever.. and as someone else said ...the only con I have is...you do not want to get out of bed in the morning.. It's like sinking into a little piece of heaven!! Love you, Berkshire !!!!!!!

Rated 5 out of 5 by from BEST FLEECE SHEETS EVER Please continue to carry these Polarfleece Sheets. Microfleece sheets are not as good as these. I use them summer and winter. They are not hot in summer, just comfy. We sleep in a cool room year round. Thanks for listening.

Rated 1 out of 5 by from Moonbeam is grey Very disappointed in the color moonbeam. It looked off white on my computer but when it arrived it is grey. The color should always be given and you can add a descriptive. This should be called grey moonbeam. Also I ordered the sheets on cyber monday with the promise of a free throw which I never received.

Rated 5 out of 5 by from HEAVENLY, BLISS. Can't get enough of them since intro from daughter. not to much pressure on top of you, but plenty to keep a draft away. i'll tear and make bandage balls of all my regular sheets. the weight of the sheet makes bed making a easy job. my other child bought a different brand but after first laundry they pilled extremely. BIRKSHIRE has cornered the market.

Rated 5 out of 5 by from Great quality and sooooo warm!!!! Bought the queen sheet set for my mom, she loves it. Keeps her very very warm. Better alternative than an electric blanket which I worried about her using. Highly recommend.

Are these made in America? Thank you.

Asked by: Julian
I’ve put these sheets away in storage for the summer and fall seasons.  They are the best sheets and only sheets we use for winter.  It’s wonderful getting into bed in the wintertime and our bed sheets aren’t freezing, as would cotton sheets would be.  And so with them in storage, I don’t know if they are made in USA.  Berkshire is a great company.

looking for grey king size polar fleece sheets. Do you have any idea when they will be available?

Asked by: Janis
I have no idea when grey sheets will be in stock.  But I can tell you that I love my sheets and recently purchased another set.  So no matter what color they come in, they are well worth the price and then some.
