I just bought 8 packs of Abena M2's on Craigslist for $80.00. That's 192 diapers, for $0.42 per diaper, that has a reported absorbency level around 3100ml. Excellent for more discreet wear but still very useable and comfortable. Being an Abena, it's not the most durable thing and may have issues clumping and breaking down a bit, but they are still very viable and worlds better than anything else at that price point. These lighter weight, more flexible and discreet diapers will supplement my SBU Simples very well. I have a few days during the week that have 3 hour classes back to back with a lab right afterwords and the Simples are a god send for that time. There are other days that I only have one class for a couple of hours and the Simples are overkill in that setting.
