Love being able to change with the seasons!
Size: 20 x 20 inches, Style: 4 Pack
I’ve been using the Amazon Basics Square Hypoallergenic Pillow Inserts with my seasonal pillow covers, and I absolutely love them. I like to switch out my covers each month or holiday, and these inserts make it so easy to keep my living room looking fresh and festive year-round.
They hold their shape really well and give my pillows a full, plush look without feeling too stiff. I also appreciate that they’re hypoallergenic, which is a big plus for my home.
Overall, these inserts are a great staple to have if you enjoy decorating with interchangeable covers. They’re comfortable, reliable, and perfect for keeping up with seasonal décor changes. Highly recommend!

If you like your pillows plump, these won't do it.
Size: 20 x 20 inches, Style: 4 Pack
Disappointed in this item. they do not have enough filling in them and what is there flattens out very quickly. Will not purchase this brand again.

Hands down best hammock accessory
Color: Green, Size: Medium
Tried many, this pillow is perfect. Not too big, not too small. Soft yet supportive. It’s also well made and super comfy. Plus it packs up nicely. I’m a new Wise Owl convert, everything I’ve ordered so far has been excellent quality. Just wish they kept the colors consistent so it all matched (minor annoyance). You need this.

Comfy, soft, packable, and cool
Color: Green, Size: Small
I absolutely love this pillow. It's well constructed but not OVER constructed - it is soft, comfortable to my neck and head - very packable and stays pretty cool - like the 'other side' of the pillow. I also appreciate the stuff sack that Wise Owl sends with it. I was able to get this down into my right side of my Redwing 50 pocket. This thing fits everywhere and while some folks think its a luxury, when you get to be my age - comfort is something that you take for granted. I feel well rested after a night on this bad boy.
Shape always fluffs back out. I think it's a great value at the price point it is at compared to other pillows in this range. Very very durable, like all Wise Owl products I own. Easily fits snugly into the bag, and can mold around you depending on how you want to adjust it. I don't use a sleeping pad, just this for my neck support and it really is worth every penny.
Water resistance - I'm not sure as I've not had the opportunity to see it but I feel like with the material it is, water would probably bead off in light amounts.
