The liner inside holds your body heat in, so the same walk or workout runs hotter and ends soaked. Zips over a sports bra in seconds, and the shaper fit holds your core in from the first zip.

Women's zip sweat vest
DM
Saw the ad three times before I caved. First walk I unzipped it and just started laughing. It's drenched every single time.
PS
I thought it would be stiff like a wetsuit. It's soft, it zips over my sports bra in two seconds, and nobody can tell I have it on under my hoodie.
CR
Get the 3 pack. One is always in the wash because you will actually soak these. I rotate the colors and I am glad I did not buy just one.

Straight answers
Questions, answered.
How does Buy 2, Get 1 Free work?
Pick your size and choose the 3-Pack. You pay for two vests, the third is on us, no code needed. Works out to $18.66 a vest.
Do I have to change my workout?
No. Do the walk, class, or session you already do. The vest holds your heat in so the same effort runs hotter and sweats harder. The free 14-day program is there if you want a plan.
Will I actually see results?
Results come from moving, eating decent, and showing up. What the vest changes is how hard each session hits, and the shaper fit smooths and supports your core the second you zip it.
Is it stiff like a sauna suit?
No. It runs hot because that's the job, but the fabric is soft and thin enough to hide under a hoodie.
Why three instead of one?
Because you'll soak it, and a soaked vest goes in the wash. Three means there's always a dry one ready. It's also the only way to get all three colors, the lowest price per vest, and the free program.
What's the 20% back?
Every 3-Pack order earns 20% of what you paid back in store credit, added to your account shortly after your order. Spend it on anything at Kewlioo.
What do I wear under it?
A sports bra, tank, or thin tee. A lot of women keep it on under a sweatshirt after the workout to keep sweating through errands.
What size do I get?
It runs small, so most women size up. Sizes go S/M to 4XL/5XL, all three vests come in the same size, and exchanges are free for 30 days.
Can I machine wash it?
Yes. Cold wash, hang dry, that's it.
When does the program arrive?
In your inbox right after you place your 3-Pack order.
How much is shipping?
Standard shipping is $5.95. On the 3-Pack, add the $9.99 Waist Trainer Wrap and the whole order ships free, so the wrap works out to about four bucks.
The fix isn’t more time
The problem isn’t your effort.
It’s your heat.
A cotton tank throws your heat away the second your body makes it. This liner keeps it on you. Same 30 minutes, three times the sweat, and you can see exactly what you did when you peel it off.
Train hotter.
See it faster.
See it faster.
Last thing
You've watched her do it. Your turn.
Trap the heat. Follow the plan. Make the next 14 days the ones that finally show.
