  • FULL BED COVERAGE FOR COUPLES, PERIOD & POSTPARTUM PROTECTION At 80x80, this blanket covers a full double or queen size bed completely. Designed for the moments that matter most time together as a couple, period nights, postpartum recovery, baby nappy-free time, or a spill nobody planned. A period blanket for bed, and a king size waterproof blanket for the nights that need one. Silent, odour-free, and completely leakproof, so you can relax and rest without a second thought.
  • ULTRA-SOFT DUAL SHERPA FLEECE PLUSH & COSY, NOT CRINKLY One side deep plush sherpa, the other smooth micro-velvet fleece. Soft, warm, and luxurious nothing like the cold, crinkly feel of plastic waterproof covers or stiff water proof blankets. 220 GSM of extra thick comfort, with the sealed layer hidden between the two faces. Absorbs up to 50oz on the surface
  • TRIPLE-LAYER PROTECTION Sherpa layer absorbs surface moisture while the silent and not toxic TPU membrane stops anything reaching through to your sheets or mattress. 50oz of capacity on this 80x80 period nights, postpartum recovery, incontinence, adult play, and the quiet intimacy blanket you reach for without planning it. Designed for water-based liquids not for oil-based products.
  • MACHINE WASHABLE IMPORTANT CARE NOTE Machine washable and dryer safe. To protect the waterproof membrane: wash on a gentle cycle and tumble dry on LOW heat only. High heat degrades the TPU layer over time. Due to the waterproof backing, waterproof blankets take longer to dry than a regular throw allow 6090 minutes on low heat. Follow this and it stays fully waterproof through hundreds of washes, and the black color stays deep.

Description

Which size do I need: 40 x 45, 50 x 80 or 80 x 80 in? The 40 x 45 in is for a lap, a chair, a car seat or travel. The 50 x 80 in covers a Twin mattress edge to edge, or two sofa seats. The 80 x 80 in is the waterproof blanket that covers a Queen with overhang or a King surface, or a whole sofa. How much does each size hold before it goes through? 40 x 45 in stops 20oz, 50 x 80 in stops 30oz and 80 x 80 in stops 50oz. The sherpa absorbs on contact and the sealed waterproof blanket layer keeps the mattress or the sofa dry, so nothing has to be interrupted. Simply remove it when you are done ;) Does it feel like plastic, and is it safe for sensitive skin? No plastic feel and no crinkle: the membrane is sealed between sherpa fleece and micro-velvet, so nothing plastic touches you. It is a hypoallergenic blanket with a BPA-free, phthalate-free TPU layer, OEKO-TEX Standard 100 certified. Can it go in the dryer, and does it need any special detergent? Machine washable waterproof blankets take ordinary detergent and a cool wash with a fast spin, then tumble dry on LOW heat only. The one hard rule is no fabric conditioner: it coats the membrane and the seal stops holding. Allow 60-90 minutes on low.

Dry as can be
Size: Large (80"x 80") Color: Purple
The absorbency of the blanket is phenomenal. Keeps all that liquid locked inside and doesn't let anything leak out.....whatsoever! Amazing.

Fantastic 10/10
Size: Large (80"x 80") Color: Black
Money well spent, it works exactly as needed and is easy to clean (you just need to do an extra spin cycle). It’s also very soft and never leaks through. It fits my bed perfectly and is very comfortable.

You would never guess its water proof!
Size: Large (80"x 80") Color: Dark Red
This was one of those random purchases but man am I so thankful I did. It has become my favorite blanket hands down for a number of different reasons. It is so soft, has a good weight to it (which I love on my period days), & the fact that it is water proof but doesn't feel like it makes it so versatile. I truly use it for EVERYTHING. Super happy with my purchase definitely one of the higher quality throw blankets I own now! ... show more

100% recommended
Size: Medium (80"x 50") Color: Black
Works as advertised! As a throw blanket it's soft and warm. No crinkly stuff inside, you'd never know it was anything other than a blanket. Care is easy, I've just been washing on a delicate cycle with no softener and put in the dryer on air dry for one cycle, then lay it flat. No signs of wear and it still works perfectly after several months. Nice and big so you can use it multiple times and feel free to move around. The waterproof qualities have yet to fail so the bed stays nice and dry. ... show more

Game changer for the bedroom
Size: Large (80"x 80") Color: Black
This thing is amazing!!! Feels great on the skin and kept the bed dry after a hitachi tsunami. We have tried so many things to try and keep the bed dry. Everything either didn’t keep out everything or was just a tarp and plastic was such a mood killer. Pro tip: Nothing that holds this much fluid is going to be as simple as a regular blanket to wash. It’s still very easy, wash on gentle, then hang to drain in the shower over night (it weighs a ton when fully saturated) then a quick floof in the dryer on low heat for no more than 20 minutes. There seems to be some kind of rubber like membrane between the two super soft sides and I imagine exposing it to repeated high heat drying might break it down. Still it’s totally worth it. Fun time gets more exciting when you don’t have to hold back. I want to get one for the sofa next. ... show more

Great buy!
Size: Large (80"x 80") Color: Black
Great purchase. It’s thick and warm. The black is luxurious and incredibly soft. We keep it on the bed full time. Great washability. I was impressed with how well it kept everything underneath dry once the fun began. We went with the larger size as it fit our needs better and helped ease her mind once the squirt became a geyser!! ... show more

Great guy!!!
Size: Medium (80"x 50") Color: Black
Great blanket, it is comfortable. It is waterproof, my wife love it for when mother nature visit her. It has some weight to it. Washing is easy, only negative is it takes a long time to dry.
