FAQs
Yes, absolutely! It may seem strange to imagine wearing wool in the heat, but merino is not like other wools. Its lightweight fibers are designed to manage moisture — naturally.
Yes, but it's usually unnecessary. If needed, use a low heat setting and a pressing cloth to avoid damaging the fibers.
Merino wool is generally not itchy because of its smaller and finer fibers that bend when they touch your skin, unlike traditional wool fibers that stay rigid and irritate the skin. EFRTLESS sources superfine merino fibers, carefully hand-picked by growers, ensuring softness and comfort. These luxurious fibers make merino wool suitable for next-to-skin layers, as they help provide less itchiness, resist odors, and move sweat away from your skin. To maintain the softness of your merino wool garments, follow the care guide for your garment. Experience the softness and comfort of merino for yourself.
Yes! Our Merino wool and lyocell knitted fabric has natural elasticity, allowing it to stretch and move with you. It also retains its shape after repeated wear, making it a durable and flexible choice.
Merino wool won't shrink after washing due to its internal spring-like coil that holds its shape. Our machine-washable garments containing merino wool maintain their softness and performance. Hang to dry and store folded for best results. With its natural stretchiness, merino wool retains its shape wear after wear. As always, follow the care guide for your garment.
Pilling can occur with any natural fiber over time, but Merino wool and Lyocell are highly resilient. Washing inside out and avoiding excessive friction from backpacks or rough surfaces helps minimize pilling.
Overall rating: 4.6 / 5 from 10 reviews.
This fits me really well and the cut is super flattering. I taught a fitness class in it this morning and it felt great. The seams down the sides are a little uneven, one comes forward of my hip and the other one a little behind. But not a huge deal and nothing noticeable to anyone else. I ordered the small and it's definitely a small but the tag does say medium. I'll be wearing this often!
Perfect to wear anywhere! I liked it so much that I'm going to hand-wash it!
I wish the neckline was a bit lower and there was a built-in bra, as wearing a plastic sports bra defeats the purpose of the plastic free tank. Otherwise, the tank is great.

Store owner replied: Hi Lena! Your feedback is super helpful. I’ll definitely lower the neckline in the next batch, and we’re releasing a new tank with a built-in bra next month! So glad you otherwise love it!
The wool tank is a closet staple piece that I have worn over and over again! It’s so well made and the quality of the fabric has kept the tank looking like new. It’s so comfortable and I stay cool in 100 degree Texas heat! I can’t wait for new pieces!
100% Plastic-free Yoga Tank Top
Store owner replied: Thank you so much! We’re thrilled that you love the tank. Our next drop is coming this October—stay tuned!
The material is wonderful. I will definitely use this shirt a lot and I’m grateful to not be wrapped in microplastics. To me, the only downside of buying this shirt was struggling to get a size that fit me. All my shirts are either XS or S, but the only size that fit me in the Effrtlss yoga shirt is a large. I don’t care about wearing a large. I just didn’t know that’s what I needed to order. When I first bought the shirt, I ordered a small. Then, I ordered a medium, which was still way too tight around the abdomen. I am fairly slim and my abdomen is almost completely flat. Maybe you should recommend that people order two sizes up from their typical size.

Store owner replied: Hi Moani, Thank you so much for sharing this with me! I’m really happy you love the material, but I’m sorry it took a few tries to find the right size. Your feedback is honestly super helpful. I’ll definitely be adjusting the fit and sizing for my next release. Thank you again for helping me make the shirt better! 🤍 Hanchen
Exact sizing guide. Quality material. Luxurious performance and feel. Bonus garmet bag included for laundering. Exceeded expectations. Ordered another.
5/5 Stars - Absolute summer essential! I am in love with this tank top. The material is fantastic and feels incredibly breathable, making it perfect for hot summer days. Highly recommend!
Love this shirt and this mission!! What a great company all around
I loved it, it's a bit too tight on me because i recently gained some weight, but now i'm losing weight and I think the size will fit perfectly. I just want it in a lighter color, as it's hard for me to wear black during the day sun, and I definitely want to wear it anywhere (not only for yoga).
Beautiful fabric and fitting. The only thing is the sizing. Normally, I wear size S but I had it size up to M just in case. Luckily, I did but it's still a tight fit.
