IR gear is awesome. there is no other choice in my book, most durable longest lasting product backed up by great people with a great warranty/service. also, no one is pushing as hard in the R&D dept. to make warm, light, quick drying gear or the dryest outer 4 layer tops and suits.
And for the record: It only takes 1 person to zip up the back entry dry suit. With no problems or issues. if you have a buddy handy, bam you are in quick, but if you take your time and do not jerk it, it is a breeze after a try or 2. there is a video on the website that demonstrate how.
the back entry keeps any chance of water from entering like the cross chest zippers and the range of motion is not even restricted like on the cross zip type.
best stuff you can buy.
