Quick answer

PUL covers are waterproof, easy to clean, and budget-friendly. Wool covers are breathable and naturally antibacterial but require lanolizing. Fleece covers offer a middle ground with good breathability and no need for lanolin, but they are less waterproof. Your choice depends on your priorities for absorbency, breathability, and maintenance.

PUL Diaper Covers: Waterproof and Low Maintenance

PUL (polyurethane laminate) covers are the most common choice for cloth diapering. They are completely waterproof, easy to wipe clean, and dry quickly. Brands like Thirsties offer hook-and-loop or snap options, with sizes that adjust via rise snaps. The Thirsties Duo Wrap, for example, comes in two sizes and is known for a trim fit, though some users find the sizing runs a bit small. PUL covers are ideal for daytime use and outings because they contain leaks reliably.

Wool Diaper Covers: Breathable and Natural

Wool covers are prized for their breathability and natural antibacterial properties. They can hold several wettings before needing a wash, and they regulate temperature well. However, wool requires lanolizing to maintain its waterproof qualities and must be hand-washed. Ruskovilla offers a silk balaclava that, while not a diaper cover, shows the brand's commitment to natural fibers. For wool covers, expect a higher upfront cost and more maintenance.

Fleece Diaper Covers: Soft and Breathable

Fleece covers are a synthetic alternative that offers good breathability without the need for lanolin. They are soft against the skin and dry quickly. However, fleece is not as waterproof as PUL and may leak with heavy wetters. Fleece covers are a solid choice for daytime or as a backup, but they may not hold up overnight. They are also machine-washable and durable.

Tradeoffs at a Glance

  • Waterproofing: PUL is fully waterproof; wool is water-resistant when lanolized; fleece is breathable but not waterproof. Choose PUL for leak-proof overnight or outings.
  • Breathability: Wool is the most breathable, followed by fleece, then PUL. Wool is best for hot climates or babies with sensitive skin.
  • Maintenance: PUL: wipe or machine wash. Wool: hand-wash and lanolize. Fleece: machine wash, no lanolin. PUL and fleece are easier for busy parents.

Product Facts

  • Thirsties Duo Wrap - Hook and Loop: Size One 6-18 pounds (runs smaller, 4-15 pounds or so). Size Two 18-40 pounds (runs smaller, 15-30 pounds). Hook-and-loop closure. Rise snaps. This means you may need to size up earlier than the label suggests. The hook-and-loop closure makes it easy to adjust fit, especially for wiggly babies.

If you prefer a minimalist cover that is gentle on sensitive skin and fits a wide weight range, this is a straightforward, economical option.
