Single Gusset Covers
The Flip Cover, Lalabye Cover and Grovia Shell are all single gusset covers. The gussets are the stretch of elastics that cover the leg area. Some diapers have double gussets as an added layer of protection, but I’ve never had a leak out of a single gusset cover. Both gusset options work from what I’ve experienced.
The Flip and Lalabye covers both have front and back flaps to hold down inserts, flats, or prefolds. This is great because sometimes the absorbency option you chose can slide up through the front or back of the cover and cause wicking on to the little one’s clothing. The front flap on the Flip is the more structured, whereas the back flap on the Lalabye is the more structured of the front and back flaps. We prefer a more structured front flap for our tummy sleeper. Both options are great depending on your needs.
The Lalabye cover has universal snap options under both the front and back flaps. This is great because you aren’t tied down to one particular brand of snaps. If the snap you purchased has universal snaps (Kam size 20), it will work with the Lalabye system. I love this because what a family may need for their 6 month old may not be the same set of needs when their little one is 18 months old.
The Grovia has proprietary snaps at the top and bottom of the shell – meaning only their brand of inserts will snap into the shell. The Grovia doesn’t have flaps to hold non-Grovia inserts or prefolds down, but it’s inner material grips onto fabric and holds it in place. We used this with a Flip Overnight Cotton Insert (a prefold) and it didn’t slide up at all. I was very pleased with this shell as a cover for a prefold and a fitted.
I think my favorite style option between all three covers is the Velcro (aka aplix, hook & loop) option on the Grovia Shell. Sometimes we go through phases where we are in between snap settings. Velcro eliminates this phase by giving an exact fit every time.
The Flip cover is shorter and wider, but we still get a great fit at 28lbs. The wide crotch holds pretty much anything. I appreciate how I don’t have to tuck in some prefolds like I do with other covers that are cut more narrow in the crotch.
The Lalabye cover and Grovia Shell are extremely similar in physical size. Even with the sizing looking similar, we get a glove like fit with the Grovia and an okay fit with the Lalabye. This may be the material, the difference in number of rise columns, or the difference in elastic thickness. There are so many variables when it comes to sizing and fit. Every child it shaped different so what works for us may not work for you. Most people I’ve talked to love the fit of a Lalabye cover.
None of these covers/shell absorb, but they have products sold to work best with each cover.
Flip has a system with Organic Cotton daytime and nighttime inserts (called inserts, but they’re really prefolds). The nighttime option holds 14-16oz. We’ve washed our night inserts many, many times and they still looks brand new.
Grovia has 2 main options for their proprietary snap system: a no-prep microfiber insert and an organic cotton insert. These snap in insert hold 7oz and 10oz respectively. With the mesh inners ability to grip, your options are endless as far as absorbency options go.
Since the Lalabye has a universal snap at the front and back of the diaper, you really can use anything with a Kam size 20 snap; which is the snap size of most everything on the market. If you want to stay brand loyal, the bamboo inserts from their AI2 system will work with their cover and these hold between 10-12oz.
Both the Flip and Lalabye covers are made with waterproof and wipeable materials; PUL and TPU respectively. This means these covers can be used a handful of times before needing to be washed. Simply wipe and replace the absorbing layer for continued use.
The Grovia Shell uses TPU as their outer layer with a mesh inner. Since my son is in the toddler phase, this shell is a single use cover for us because the mesh can’t easily be wiped. However, if your little one isn’t a heavy wetter, you can use this cover a couple times if the absorbing layer(s) doesn’t wick the urine onto the mesh.
