One Size- Booster
Bella Luna Boosters feature a hidden layer of Zorb just under the top layer of bamboo. Zorb is a great addition to the bamboo as it increases the speed of wetness absorption, absorbing 10x it's weight in half a second (that's 20x faster than any other insert material!!!), works to evenly distribute wetness throughout the booster, and dramatically decrease compression wicking.
In total the booster features 2 layers of heavy weight bamboo fleece and 1 layer of zorb.
Bella Luna Boosters arrive to you having been washed once. It is recommend that you wash a few times prior to use, keeping in mind that, as with all natural fiber inserts/boosters, they reach max absorption after 8-10 washes.
