WOW. I am obsessed with this sweater!! It’s so cozy, so unique, and the fit is amazing! I am a women’s size 6 and I bought the M/L for a little oversized fit! This feels and looks like such a quality garment and I will definitely be ordering from Back Beat again.

Cute as heck

Sturdy warm summer sweater. Recommend if you are heavy chested and aren't looking for a super cropped sweater. 5'2" size 4/6 and the M fit perfect! Love it so much!

Soft slouchy perfect sweater

I'd wear this every day if I could get away with it. It's the perfect slouchy sweater. Only thing to watch out for is, the sleeves are so balloony that they get dirty easily from whatever's on the counter/table/etc. But besides that it's perfect and I love it!

Love this sweater

Just an amazing sweater - so cozy and cute. For context I'm usually a M and sometimes need to size up to a L so was unsure about sizing but the XS-M is totally fine, still oversized on me. Also love that the sweater comes with a card informing you on how to take care of knits which is so helpful.

The only sweater you need...

I absolutely adore this wave sweatshirt! You really can wear it up or down and both ways you’re bound to look cute! I’ve worn it with some high waisted black jeans and then I’ve worn it on my lazy days with some sweats. PS - I’m moving to WA soon, so I’m happy to have a sweater that’ll remind me of my CA beach waves ✨

Wore it 4 days in a row when it arrived

This is the softest & most comfortable sweater I’ve ever owned. It’s going to be a great transitional piece into spring & even for summer nights at the beach post-surf. Love Back Beat!!

Wave Sweater, Amazing fit!

I ordered the wave sweater in a M/L size. I ordered it even though I’m 7 months pregnant because I wanted to make sure I got one before they ran out. I didn’t think it would look cute on now but it totally does and it will fit even better after baby! I’m on the shorter side and the length is great.

Coziest Sweater Ever

I. Love. This. Sweater. I’d been waiting to purchase for months and the color I wanted was always sold out. Enter the newest release of colors! I purchase mine right away and I love it. I went with the xs/sm and it fits perfectly. I’m rather ***** but have a more petite bottom half and it fits great. Worth every penny.

Honestly, someone in another review mentioned that all of their sweaters need to live up to the Back Beat Co. quality... and I couldn't agree more. This sweater is so beautiful, soft, and cozy. The color and design are so gorgeous! I might pick up another color palette down the road as I can't get enough of this gem. I hope Back Beat Co. makes more sweaters with this silhouette / knit. I definitely recommend it!

Comfy and well made

Great! Arrived somewhat quickly. I wore it a lot when I first got because it is comfy and goes with everything. The XXL is not that big, but was the only size left. I’m usually a Medium and the XXL for like slightly baggy.

Love love love

I’m a beach lover in a landlocked state so as soon as I saw this sweater on Instagram I had to have it! It’s a bit pricey but for the quality and unique design I really do love it so much!! I’m 5’9 and the S fits a little longer than a crop, But it’s also loose so I like the size. If I order another color I may go up to the M/L and see if I have a clear favorite on the size. It’s so cozy, I can’t wait to take this on my travels once that picks up in the future. If this caught your eye you won’t be disappointed upon arrival.
