My questions are:
1.How strength / firm is the suit without 3D liner, compared to other suits (D7,..) - I like to say it is bulletproof - but I crawl over the inlet rocks in my suit - NJ Inlets have very large and dangerous rocks that they use for an inlet barrier.
2.If you can, put it on weigh (or weigh with suit and without and do difference) please. I cant google the exact suit weight. - I have a medium and it weighs 6 lbs.
3.It is possible to put liner completly out and use suit without liner? - yes you can pull it out and hose it down or hand wash if needed - it uses velcro and zippers to keep the liner in and attached.
4.It is possible to zip/unzip yourself, when you use tool (line, carabbin.. etc) - Yes I have many times done solo in my suit - I use a wooden block and cave line but it works with a tool - at least for me.
