The TECH PLUS is the feature rich, high spec 10mm padded, ripstop protected bag with new upgrades; the zip is now a YKK molded zip - a heavy duty zip usually reserved for travel coffins. And one side of the external lining is replaced with a high resistance woven silver reflective material to keep the bag cool and added durability. The expandable tail area, buckle free removeable shoulder strap with 3 attachment points and wetsuit pocket are kept as standard.
