aden + anais Organic Cotton Light Sleep Sack review

aden + anais Organic Cotton Light Sleep Sack ranks eighth. The brand, best known for muslin swaddles, now sells through the same store as HALO, and this sack is its everyday organic cotton option. It carries a 1.0 TOG rating for rooms from 68°F to 75°F, which suits a typical nursery a little better than HALO's lighter 0.5 TOG cotton sack. A bottom-up zip opens for diaper changes, and the sack is cut extra long so you size up less often. Sizes are three age bands, 0 to 6 months, 6 to 18 months and 18 to 36 months, so a family may buy only three sacks from birth to age 3. The drawback is price: at $49.99 it costs $15 more than the HALO cotton sack, and sizing by age rather than weight leaves more room for a poor fit on small or large babies. It has no transition wings. We compared documented features and published prices.
