Fans Rave: Clothes Don't Get More Effortless Than This

"Soft, cool, breathable"

This is a fantastic find - yesterday in Florida the temperature ranged from around 60 to 85 - and my Summer sweater was perfectly comfortable, inside, outside, sun and shade! I appreciate that it's light weight, soft, cool, and breathable.

"Blown away by versatility"

Blown away by its versatility - it could be 85 outside and 66 inside, and I was comfortable in both temp ranges... How is that possible?! In 30 days, I washed 3 times and had no issues with smells. No one even noticed that I was wearing the same sweater everyone day!!

Seamless 3D-knit is amazing for people with sensory issues

I wasn’t sure what size to order, and after consulting with customer service went with a L, which is my normal size, even though the size charts indicated a smaller size might work. While the L does fit, it’s roomier than I typically wear, and the hem and sleeves were a bit long. For people who are between sizes and like a roomier fit, I’d recommend sizing up. For those who like a more snug fit, size down. Otherwise, the cardigan was amazing! Goes with everything, a very versatile style and color that works just as well for lounging as it does for work or dressing up. Minor pilling after seven days, but apparently if I wash with jeans (zipped up) the pills will be removed! The seamless 3D-knit is amazing for people with sensory issues, and the SeaCell is both warm and breathable in a way synthetic fabrics just can’t match.

I like the feel of the sweater and it will be a good layeing basic for cooler seasons

I like the feel of the seacell sweater - like a soft cotton sweater but just a bit silkier. I think the name “summer cardigan” is a bit of a misnomer though. Its is a little heavier and warmer than I thought it would be. I do not think I could wear this cardigan in the summer. But I will wear it in fall, winter and spring. It will be a good layering basic for cooler seasons.

The material and color is gorgeous

I was surprised that the cardigan did not have buttons even though it clearly does not from the photos. I did get used to it pretty quickly. The color is absolutely gorgeous, as is the material. I can’t wait to travel with it, either. Like many, I did find the cost a little prohibitive, but my curiosity got the better of me. Overall, it’s worth supporting a small business trying to make a dent in the wall of fast fashion and ecologically problematic textile manufacturing.

I really want more of them

The 3D knitted no seams was probably the deal maker for me. I wear an apron every day at work and one more thing rubbing on my neck or underarms is just an issues. This sweater is great I love the smoothness of the build of the sweater. I also really like a company that is willing to sell a quality garment that they will stand behind. The pledge to repair the sweater was really another thing that drew me to trying the sweater. I was more than pleased with the feel. Of the knit material it is made from. I really want more of them.

I was wondering what a sweater made of seaweed would be like

I’ve enjoyed sharing my experience with buying and receiving my SeaCell sweater. I was wondering what a sweater made of seaweed would be like and I was very pleased with the garment I received. I would recommend this sweater to anyone looking for a quality sweater that is a nice layering piece.

I bought because of the lifetime backing

I was drawn by the no seams knitting of the brand. I hate seams! I bought because of the lifetime backing! The color is better than my monitor showed. I love the fit and feel so far!

Love, love, love it!

Love, love, love it! Getting softer with every wash. Nice neutral color - goes with everything! Jeans, dresses, shorts all look snazzier with this cardigan. Easy to dress up or dress down. AND it is SeaCell!

Slowing down fast fashion

I gave it 4 starts instead of 5 not because of a design or materials flaw, but because it is larger than I thought it would be. Otherwise, this sweater us great for someone else looking to simplify their closet and make a commitment to high-quality pieces that will last a long time. I like wearing close-fitting, lightweight tops and layering, bc I get hot easily at work as a kindergarten teacher. The sea cell cardigan is the perfect combination for this kind of lifestyle/wardrobe. I started the challenge eager and open-minded. I’d really wanted to start with a wool sweater, but it was still hot where I live when I ordered, and I was SO eager to see one of these cool garments, that I opted for the seaweed blend, bc it would be cooler and more flexible for my adventures.

It is SO soft, the color is pleasant, and I love that there are no bulky seams. It’s the perfect weight to wear to the coast over a tank top, or a cooler morning or evening walk. As a result of the sweater being larger than I’d expected, I will probably not wear it to work as often as I’d originally hoped. It will continue to be a comfortable layer for these early fall days, and again in spring and summer, as I begin to wear tank tops again. I really enjoyed telling people that the fiber is seaweed-based! Friends were eager to touch it! I was also excited to share that because of the unique manufacturing process, it’s practically zero-waste! I look forward to trying a wool sweater next and sizing down, and wearing the heck out of it all winter! The idea of slowing down fast fashion is very appealing to me.

Quality of the fabric is awesome

I love my summer cardigan! It keeps me warm but also isn’t too heavy that I can’t wear it during the summer. It goes with everything. The quality of the fabric is awesome. Feels really nice on the skin. I’m not proud to say, I live my busy life kinda chaotically at times - sometime leaving clothes on the floor / in the car / crumpled up in a gym bag, you get the idea. The Oliver Charles sweater has kept up with this busy lady! I’ve had the sweater over a month, have not washed it and have worn it frequently and it still looks and smells as good as the day I got it. I got a size large which ended up being a little roomy so maybe for my next OC sweater I’ll size down. But oversized sweater still looks cute.
