Material: 95% Cotton, 5% Spandex, with a slight ribbing effect; nice and weighty and sturdy, as with many Nasty Pig products. Every once in a while, it makes me itch a little or gives some general sensation of pull/dryness in areas where the fabric is consistently stretched, but it's generally soft and warm, so not too bad overall. The discomfort might simply be me - I've always had sensitive skin, and I get the same feeling when tall socks are stretched over my upper calves, so it should be little to no worry to most of you, especially since I've only noticed the "problem" over my calves or shoulders instead of over the whole suit, which supports the thought that it's not a problem with the material overall.
Aesthetic: Since it's one solid color, nothing sticks out much on first glance. However, the NP logo is nicely placed right where the logo on a regular polo shirt would be, giving a pseudo-professional look that you wouldn't expect for an under-layer. Next of course is the series of button snaps that goes all the way from the neck, down through the crotch, and around up to just above the butt. This looks much slicker than the traditional butt-flap on union suits from days past.
Coverage: As a union suit, it will completely cover your back, your arms, and your legs. With that much coverage, the occasional annoyance from the fabric is not-so-occasional, but as stated above, that might be just me. The full coverage grants some level of modesty, maybe enough to make you feel comfortable being seen in various situations with this showing. It also is great cold-weather wear, either under regular clothes or lounging about the house, as it completely covers your arms up to the wrists and legs down to the ankles, keeping those extremities a bit warmer than otherwise.
Access: Any full-body piece of "underwear" such as a union suit, a onesie, or a singlet isn't going to come off easily if you need to go to the bathroom (or want to do other things that need access). Union suits are generally the best of the full-body underwear as they're usually designed to have access of some sort, and the Nasty Pig union suit does not disappoint! The long-line-of-snaps design eliminates the bulkiness and hassle of the traditional flap design, making it incredibly easy to go #1 or #2 (or do other things that need access) - and, as a bonus, it's easy to show off your chest and/or abs whenever you want, too! Just undo whichever snaps are needed.
Overall: 3.5/5 - you should get one, but just one. Maybe two if you're gonna be "using" it with someone often, but they're expensive and always sell out really quickly each year. (Also, since they sell out, the colors they make each year seem to vary - the 2017/18 batch of Union Suits seems to not include blue, instead favoring a new grey option to compliment the black and red options.)
