Petzl Kids

Frequently Asked Questions

• Which Petzl kids' harness is best for my child's age and activity: Ouistiti, Macchu, or Simba?

  Choose based on age, activity, and growth needs: the Ouistiti is a full‑body harness sized for infants/toddlers (waist 58–70 cm, legs 32–40 cm, up to ~30 kg) and prevents flipping for very young climbers, the Macchu is a highly adjustable sit harness (waist 54–65 cm, legs 34–46 cm) that grows with kids and pairs with a Body chest harness for a full‑body setup, and the Simba is designed for adventure parks with rear adjustments that limit tampering while still offering comfort for hanging and play.
• How much adjustability do the Ouistiti and Macchu offer for kids who are still growing?

  Both are engineered for growth: Ouistiti is one‑size with primary shoulder and secondary back adjustments and color‑coded interiors to simplify donning, while the Macchu offers a wide single‑size range (waist 54–65 cm, leg loops 34–46 cm) with DOUBLEBACK buckles on waist and legs to accommodate clothing layers and seasons, plus the option to add Petzl’s Body chest harness for smaller or younger children.
• How does the Macchu compare to the Simba for mixed climbing, park use, and longevity?

  The Macchu is a versatile, adult‑grade adjustable sit harness (FRAME/ENDRAME pressure‑distribution tech, padded waist/legs, rigid gear loops, storage pouch) built to serve a wide age range and multiple seasons; it’s ideal for both indoor/outdoor climbing and progressing skills. The Simba is tailored to adventure‑park use with back adjustments designed to prevent tampering and an anti‑flip front point, making it simpler and safer for supervised park environments but less focused on climbing‑specific gear capacity and long‑term technical climbing use.
