"I am very disappointed with the communication, as the shipment process took two months. Despite sending multiple emails, I received no response. I was keen to order items for my new non-toxic wardrobe. Short looks good but has very little stretch around the waist and legs."
"Love that these are natural fiber and great for my lady parts to breathe unlike synthetic activewear. They feel great and soft on - not itchy but a different feel to synthetic activewear. I sized up and they are the perfect fit."
"Disappointed. Tights are too tight in wrong areas. Makes em uncomfortable to work out in. Top. Have to rearrange but good woth sweat. Really disappointed in the shorts. Doubt ill even wear them again. And at 150. That sucks."
"Obsessed with this shorts. Ben looking for some material fiber activewear and this is definitely one of the best brands I found!"
"These shorts are comfortable and soft, but a tiny bit itchy at times, the size is good (I wear a M size in other activewear). They are a bit see through, so definitely not squat proof (wear nude knickers or none) I have been wearing to the gym for weight lifting sessions. Worn a few times in a row and they don't smell. I noticed that they get damp from sweat but not the same as "normal" activewear, seems to dry faster too. Would buy again if they were more squat proof."
"I'm beyond happy with the set that I got! I've been slowly getting rid of all my synthetic clothing, and finding activewear is the hardest part, especially with a nice fit and feel. This set absolutely exceeded my expectations, the fit is cute as, the merino is soft but sturdy, the colour is amazing! Absolutely love what you guys are doing, I'm telling everyone!"
"Amazing 5inch black merino shorts and crossback bra - so perfect for training and teaching reformer & hot mat pilates! Love how breathable they are…"
"Non toxic fabric, no front seam, perfect length- happy customer"
"This shorts are so comfortable, the fabric is light and you can move a lot wearing theses. Please make more colorful colors."
"First time trying merino activewear and I’m SO IMPRESSED! These shorts are so flattering - I often find bike shorts to come up too high but these sit at the perfect point, they also don’t roll up at all, AND the material is so breathable. Cannot recommend enough!"
