Of the various 1 and 2 piece suits I've worn, I find getting in and out of the Down130 the easiest.
The arms and legs have zippers and inner seals, the multi-panel construction seems to lend more
flexibility than many suits without going to a "hyper-stretch" material, the quality is top notch,
and as a full suit I find it as warm with just and UnderArmor Cold Gear top underneath as my LDS
2 piece 7's.
My wife also dives one, and its really the first wetsuit she gets into easily and she finds it far
more flexible (and thus less "claustrophobic") than wearing the farmer john/jacket style. She
also finds the fit keeps her warmer than the 2 piece setup, and she chills easily.
Contact Mike at Down130 and talk to him directly. He may even be willing to let you try it
out and return it if it doesn't work for you - can't promise anything but I found him very easy
to work with.
Cheers.
