Buying Guide: Key Purchase Considerations

  • Water temperature and activity: Thicker wetsuits (3/2mm, 4/3mm, 5/4mm) are better for colder waters and longer sessions, while 2/2mm or 2mm shorties suit warmer water and casual use.
  • Fit and flexibility: Look for a snug but comfortable fit, with features like back zippers for easy entry and snug cuffs to minimize water infiltration. Flatlock stitching reduces chafing for all-day wear.
  • Durability: High-quality seams, reinforced shoulders/knees, and abrasion-resistant panels increase longevity for active kids and adults who engage in frequent water activities.
  • Protection: Consider sun protection (UPF ratings), UV shielding, and abrasion resistance when selecting wetsuits for beach days, snorkeling, and diving.
  • Ease of use: Back zip vs front zip; ease of putting on and taking off is important for kids and beginners. Front zip designs can offer more flexibility in movement.
  • Sizing consistency: Sizing varies by brand; check size charts and consider age, height, and torso length for kids. For adults, pay attention to chest, waist, and hip measurements.
  • Maintenance: Rinse with fresh water after use, dry away from direct heat, and store flat to maintain neoprene integrity and extend life.
