The Billabong Launch 4/3 back zip is Billabong's entry-level winter wetsuit: a fullsuit with back zip, designed for those starting out in surf, SUP or wing who need reliable warmth without breaking the bank.

Technology. Superflex neoprene with low-absorption Superflex 250 Jersey lining, GBS seams (Glued and Blind Stitched) with triple sealing and reinforcement at stress points. Back zip impact welded with internal heat tape to reduce water entry, and contour collar to prevent chafing. Superlight Foam with good stretch for the range.

In the water. 4/3 mm is the standard winter thickness for Mallorca (14-18°C water). Keeps you warm on long sessions, easy on and off thanks to the back zip, and flexibility is solid for beginners and intermediates. It's not a premium super-elastic suit, but it does the job: insulate and last.

For whom — how we see it at El Niño Mallorca. A solid first 4/3 for Mallorca winter, or a second suit to keep your best one fresh. If you're unsure about sizing or want to compare with the front zip version, contact us on WhatsApp or stop by the shop in Pollença.
