The O'Neill Hammer 3/2 Wetsuit is an affordable suit that is made to fit perfectly and let you move without restrictions while surfing. The Hammer is a basic entry level suit but with a few features that make a big difference in comfort. The Glide Skin Neck is a priceless upgrade with its soft rolled over neckline that reduces the nasty chaffing you get with blunt edged neoprene. Add in the super stretchy UltraFlex Neoprene and Smooth Skin Chest and Back Panels for flexibility and warmth and the O'Neill Hammer is a great budget choice for fun in cool to warm water.

Product Features

  • Double Superseal Glide Skin Neck Closure: A toasty warm two-layer design featuring a 360 smooth skin interior lining, wide adjustability and a secure lock down./li>
  • Smooth Skin Chest and Back Panels: Wind resistant panels that keep the chill out and trap the heat in.
  • Seamless Paddle Zones Underarm: An ergonomic, seamless undersleeve panel that allows for unrestricted motion and eliminates rashing.
  • Krypto Knee Padz: Abrasion resistant, high stretch neoprene panel with ergonomic shaping designed to extend the life of the wetsuit and protect the knee while punching through waves.
  • Flatloc Stitch Construction: A breathable, overlapping flatstitched seam. Non-chaffing and super durable.
  • LSD (Lumbar Seamless Design): We all know that even the best surfers spend significant amounts of time sitting on their boards. By using a single panel in the rear area of the wetsuit, water entry is minimized and stretch is maximized.
  • #10 YKK Zipper: Heavy duty easy glide zipper that reduces water entry.


O'Neill Hammer 3/2 Full Wetsuit Exactly as advertisedReview by Cavemanbob Cavemanbob
Little glitch on the $10 coupon but the guys made up for it by sending me some sex wax and starburst. The 3/2 is just the right thickness for this time of year. Would recommend full gloves and booties too.
