Dinan High Flow Drop-in Replacement Filters are a direct upgrade to your factory intake system and will instantly provide better flow to assist your engine in achieving maximum performance and efficiency! While factory paper filters function admirably, they can be restrictive to performance goals given the material used. They also require being replaced numerous times during the lifespan of the vehicle, which can add up to a substantial amount in maintenance costs. Limited performance and increased maintenance costs are never ideal but can be resolved effectively and economically in the case of filters. Dinan High Flow Drop-in Replacement Filters are constructed of 4 layers of cotton gauze that allow better flow and less pressure drop than the stock media. This equates to the engine not needing to work as hard to make the same, or more power. Additionally, the use of oiled cotton media means that the Dinan filters are washable/re-usable while still retaining excellent filtration and ensuring your engine runs clean for the duration. When upgrading to a complete Dinan intake system for best performance, is not available, possible, or within the budget, Dinan High Flow Drop-in Replacement Filters have you covered!

Finally!
Size: X-Large, Color: All Black D (5-pack)
Finally, comfortable underwear that don’t end up giving me a wedgie. I have a round booty and most cuts of underwear end up shifting as I walk and sit. The hem of the underwear comes right under my cheeks and the lightweight material ensures there’s no panty line and no shifting to where I don’t want them! I’m definitely purchasing more.

Ehh
Size: Medium, Color: Multicoloured E-(5-pack)
Very thin, still comfy but very thin material. Super soft though. I've worn and washed and they have held up but I won't be repurchasing bc these are so thin

They’re fantastic!!!!
Size: X-Large, Color: Multicoloured E-(5-pack)
My clothing size is 16/18 and XL. Even though Amazon suggested a size XXL, I ordered my normal XL and they fit perfectly.
The fabric for this style is 92% bamboo viscose and is amazingly soft and almost silky feeling. I had ordered a different boy short in this brand but they were 80% bamboo viscose and the fabric was significantly heavier. I returned those and ordered these.

Flattering fit
Color: White, Size: Large
Flattering fit and comfortable. Material is a bit see through but that doesn't bother me. Great value for a nice looking shirt.

Super Soft and Comfortable, Just Not the Most Forgiving Fit
Color: Purple, Size: X-Large
This top is incredibly soft and comfortable, which was the first thing I noticed. It has a really nice, lightweight feel that is easy to wear and not too thick or heavy, making it great for everyday use. Fit is true to size, but I would not call it very forgiving through the midsection. It is not cropped, but it also does not have much added length, so it hits in a way that can highlight the stomach area more than expected. Just something to be aware of depending on how you like your tops to fit. I know the material blend can pricey but still not sure I would say it's value is worth it. I like it, but I odn't love it. The purple color is better in person than the picture though! Overall, it is a great basic if you are looking for something soft and comfortable, just know it leans a bit more fitted than flowy.
