Buying Guide

Choose the right material

Flannel and plush offer warmth and softness while sherpa-lined options add extra insulation for colder nights

Check fit and sizing

Look for products labeled unisex or snug fit and consult size charts to avoid excess bulk or a too-tight fit

Consider costume details

Hood, tail, or applique features affect appearance and mobility—prioritize the details you’ll actually wear

Evaluate warmth vs breathability

Plush and sherpa are warmer but less breathable than woven flannel, so pick based on bedroom temperature and seasons

Look for easy care

Machine-washable fabrics and simple closures like zippers or snap fronts make maintenance easier
