Care guide

Wash sweaty Performance Boost™ garment as soon as possible after use to prevent sweat buildup.
Machine wash at 30–40°C (86–104°F) with similar colours. Use a liquid detergent, preferably one formulated for sportswear.
Avoid fabric softener, as it can reduce breathability and stretch. For a natural alternative, use laundry vinegar to freshen your gear.
Air-dry your sportswear. Avoid tumble drying, as high heat can damage elastane fibres.
If ironing is necessary, use a low-temperature setting and avoid ironing over prints.

Ei minulle sopiva.

Tosi mukavan tuntuista materiaalia, mutta mitoitus semmoinen, että ei sovi isompi rintaiselle. Ihana väri olisi, mutta meni palautukseen.

Nätit ja mukavat

Aivan sairaan nätit, mutta isommille rinnoille vähän liian lyhyet ongelmat, suosittelen pienirintaisemmille! Mutta ei mitenkään mahdottoman lyhyet olkaimet.

Surprisingly good. The bra is medium support but I’d say it’s closer to high support

Violet Vibe / XL

Violet vibe performance boost sports bra

Violet vibe, aivan upea väri! Imarteleva selkäosa, istuu hienosti myös xl kokoiselle ja riittävä tuki ainakin salitreeniin. Kokotaulukko piti paikkaansa, rinnanympärys mulla 106cm, rinnan alta 90cm ja xl koko oli sopiva. Antaisin 5 tähteä, mutta 1 tähti lähtee pois siitä hyvästä että nännit näkyvät läpi kilometrien päähän! Toivoisin todella jotain toppausta rintojen kohdalle..

Just A Really Good Bra

Snug yet comfy fit, flattering back. Material feels high quality. Overall very happy with them, it seems great effort was put into the design process. Let's see how they wear.

Performance Boost Sports Bra

Tilasin M-koon koska edelliset liivit oli samaa kokoa (ostettu varmaan vuonna 2021). Näissä uudemmissa selkeästi vähemmän materiaalia tuossa liivien etuosassa kun vertasin näitä päällekäin. Liivit oli siis mielestäni enemmänkin S-kokoa eikä M-kokoa ja tosi tiukan tuntoiset. Jätin kuitenkin palauttamatta siinä toivossa, että jos nuo olkaimet vähän venyisi käytössä. Jää nähtäväksi olisiko kuitenkin kannattanut palauttaa ja ottaa L-koko. Hurjalta olisi tuntunut kun käytän normaalisti S/M kokoisia vaatteita.

brick / S

Hyvä tuote

Materiaali ihana ja tuote napakka. Miinusta siitä, että vähän hankala vain saada pois päältä ja edestä muodot hieman kuultavat läpi. Jään koon puolesta jonnekin katvealueeseen, sillä S on vähän kiristävä olkapäistä ja M taas liian rento. Mutta jos oikea koko löytyy niin varmasti hittituote.

Parhaimmat urheiluliivit 💛

Nämä ovat yksinkertaisesti parhaat urheiluliivit ikinä! Mukavat ja sopivan tukevat, olkaimet menevät kauniisti ristiin selän puolella.

Violet Vibe / L

Parhaat urheilurintsikat

Klassikkoliivit. Tukevat ja joustavat, mutta eivät purista mistään. Ihana pirteä uusi väri!

brick / M

Comfy and stays in place in low intensity training. Doesn’t give much support for bigger breasts and feels like I would need more coverage for it to fit like it is meant to. I’m 170/70kg and took size m which I normally use. I think bigger size would be too loose.

Napakat liivit, juoksen näillä!

Napakat liivit

Tukevat ja napakka istuvuus. Pienehköä kokoa. Muutoin yläosista M-kokoinen ja otin tästä L.

Miellyttävät liivit

Miellyttävät liivit ja kauniin väriset. Itse ehkä tykkäisin että olkaimet olisi kauempana toisistaan, mutta eivät kuitenkaan paina niskaa, se on hyvä!

moonlight blue / M

Lightweight yet supportive; the best part is that they don't have removable pads. The cup size is quite small.

Sopii lyhyelle hyvin

Harva toppi sopii näin hyvin lyhyelle. Riittävän tukeva perus sporttiin.

Super comfy and nice

Between sizes

Bought size M following measurement but maybe S would have been better. M is not that supportive but works well in yoga and weight lifting. Although this seem to be a bit more supportive than the other bra. My measured size is justbetween S and M.
