Wonderful product

Keeps the mattress protected, while keeping the body temperature regulated. I love it. As is the case with all Holy Lamb products. Highly recommended.

Wonderful wool barrier, fabulous service!

HLO provided a shipping miracle and was able to deliver this prior to my having surgery. Due to allergies, I took my own bedding, and this included the wool barrier to help protect me from the foam hospital bed. This is soft, not itchy, and washes well at home for maintenance. This and the other HLO products made me the most comfortable hospital patient I'm sure! Thank you, Kat

Worth every penny

I came on here to buy more! We have had one on our calking and 2 on our boys beds for about 8 years!!! I can’t say enough!!! Made in the USA. My calking one has been through 5 babies (we are talking milk, spit up, pee and poop) and I haven’t even had to add lanolin to it yet!!! This thing is indescribable!! Also the 2 on the kids beds have been through the same amount of use or more.
I mentioned 5 babies but only 2 kids beds having a holy lamb cover...I tried to save money and buy a different brand...well it ended up costing me more because they didn’t last. Just get this one, you’ll be happy you did!


We have several of these and have been really happy with them. They are so incredibly nice and soft. The quality is next level.
