Mesh Bags

A 30u201340 litre mesh bag handles a wetsuit and fins comfortably for a single-day trip to sites like Tioman or Redang. Bigger 60u201380 litre options suit liveaboard packing where you may have multiple wetsuits and mask sets needing separate ventilation from your dry clothes bag.

Mesh allows seawater and excess moisture to drain out during the boat ride back, and air circulation dries the gear faster. A sealed bag traps salt and warmth u2014 a combination that accelerates neoprene degradation and breeds mildew in Malaysia's humidity. Rinse the gear at the dive site if possible, bag it in mesh, and hang it to dry fully when you return to your accommodation.

Mesh bags are designed for soft goods u2014 wetsuits, fins, masks, SMBs, and accessories. They are not built for the weight or abrasion of cylinders, and the open weave means small items like mouthpieces or lens inserts can fall through. For mixed loads, use a mesh bag for soft gear and a hard case or separate pouch for loose accessories.

Mesh bags themselves have no rigid frame and compress into almost nothing when empty. Most divers check them with their other dive gear rather than carry them on. That said

Heavy-duty polyester mesh with welded or bar-tacked seam reinforcements lasts significantly longer than standard nylon. Aluminium zips and buckles resist corrosion better than steel. After every trip, rinse the bag thoroughly with fresh water u2014 salt crystals that dry inside the mesh weave will abrade both the fabric and whatever gear you store inside.

Choose bags with smooth edge binding around the perimeter and avoid bags with external elastic or loose cord loops that catch on anything. Barrel-style mesh bags with a drawstring or roll-top closure tend to have fewer snag points than zip-opening flat bags. If you're on a liveaboard out of Semporna, ask the crew which hooks or storage rails are available so you can judge clearance before loading your bag.
