These are much higher quality than inserts I’ve used before! Great for my sports bras.I love these and put them in all my bras, swimsuits, and dresses that have the openings for pads like these. As a “A” cup, these give me just the right amount of lift to help me feel more confident and filled out.The material is high qualityExactly what needed. I bought some bras that came with inserts but they were so cheap that they tore. Bought these and so far have endured multiple washes without any wear and tear.These are quite durable as well as giving a little (much needed) boost. Being a person will furiously sensitive skin, I can’t wear things twice without a wash. I ruin every sports bra insert with washing(never machine drying), but these have stayed wonderfully intact and don’t fall apart which would make my chest look lumpy.So happy I found these! I've decided to make a switch to Merino wool products and I started with icebreaker bras. They're unlined but they have an opening to slide in inserts and it worked out perfectly. I'd say it's a medium thickness. I've had some that were super dense pads and I've had things that were like paper thin barely there. This is a nice middle of the spectrum.This product is exactly what I wanted . I changed all my old pads on bikini tops to new ones .Perfect for replacing the removable pads that get worn out or if you want a slightly more supportive one.I tried these with my wireless bras, wired bras and all my swimwear. They sit nicely in regular bras but not in any of my swimwear. The push-up is so minimal there's no point in using these – I am a 32C. There are various sizes for swimwear and these inserts are too big to fit into half of mine. Definitely no good for triangle bikini tops. It's too bad 'cause they are comfortable.Found it quite small, however it is as advertised. No issues with shipping etc. Held up through a wash cycle. I don't think I would buy again.I was so impressed with the quality of these inserts. I am so happy with this purchase.Nice but wish they were bigger. I would still buy them again if needed. Much better than the ones that come in bralettes/sport brasSince it's too small, the item is returned back. After a week , the refund is still not proccessed yet even though puralator dropped it a few days ago.
