Solar Charging
Pair it with EcoFlow solar panels for up to 500W of free, silent energy - a full charge in around 2.5 hours of good sun. Made for off-grid weekends at the bach or campsite.

Alternator Charging
On the road, add an EcoFlow 500W Alternator Charger[4] to top up from your vehicle as you drive - 0-100% in about 2.5 hours. Power that keeps up with the journey.

The perfect bra!
Size: 46DD, Color: Beige
This is the perfect bra! It’s comfortable, supportive, and the straps do not slide off your shoulders. The material is so soft yet lifts and shapes the sides just like they say it does while also smoothing the under arm and back area. This bra stays put all day and feels like you’re wearing nothing. It’s very well-made with the perfect stretch that covers even under a thin T-shirt. I hate to say how much money and time I’ve wasted on ill fitting overhyped bras but this one is perfection. I will definitely be buying more! My only suggestion is the band size runs a little large so I went down one band size. Cup size is right on.

So comfortable!!
Size: 38G, Color: White
This is the most comfortable underwire bra I’ve ever worn. I am a 38G cup and it lifts, shapes and supports me all day, minimizes, the back stays in place and is super smoothing. It keeps its shape through a few wears. It has great stretch. It’s so soft. Nice bright white. Perfect for an every day / work bra. And it’s super inexpensive. I’ve bought $80 bras that were horrible in comparison. The only one con it has is that because it’s so soft and stretchy, you can’t wear it more than 3 times without needing to wash it. Otherwise it stops supporting as well because it’s stretched out a bit. But I mean, we should probably be washing our bras more than we do anyway, am I right?! 😆

THE BEST. Seriously.
Size: 36E, Color: White
The world is upside down. How can a twenty dollar bra outperform my hundred dollar bras??? I don't know but here we are. I am 49, a 34F/36e, 5'1". Finding a great bra is challenging to say the least. This bra is it, y'all. I bought it in a different color a couple of weeks ago. I wore it three times in a row to make sure it wouldn't bag out, lose its support. I washed it, not in a lingerie bag, on warm, dried it on high, to make sure it would hold up to that. It passed both tests with flying colors. It is so comfortable. It feels wireless! It is very flattering, has great under-arm-flub-smoothing and support. The back is substantial and smoothing but without being bulky or restrictive. The straps are wide, but not too wide, and totally stay put all day. I bought the other three colors and the sizing is seamless across colors. This is a winner, folks!!!

Surprisingly Comfortable
Size: 36D, Color: Beige
I'm very surprised by the comfort of this bra. I've worn wireless padded/lined bras for as long as I can remember so this is quite a change from my norm. I am only 5' tall so having larger breasts tend to make me look top heavy. The minimizing effect makes my outfits look so much better and slims me down a bit. I am unsure of the sizing though. I purchased my normal size in a 36D but the top of the cups have some wrinkling as if I'm not quite filling the cup. It does smooth out a bit after I've been wearing it for a while. The lift is nice but not extreme. It more puts the girls where they were about 20 years ago but it doesn't do much for shaping. Overall it's a nice bra and I'd likely purchase again if I could just get the sizing right.
