## Overview

The Red Union Suit Onesie is a unisex, 100% cotton jersey knit pajama featuring a classic long john style with modern lightweight stretch fabric. It includes an EZ snap front closure and a humorous 'DANGER BLASTING AREA' printed drop seat flap for convenience. Perfect for year-round lounging, pajama parties, and gifting, this breathable, tagless, and machine-washable onesie blends vintage charm with playful practicality.

## Description

Red onesie union suit has funny butt flap with a DANGER - BLASTING AREA - KEEP CLEAR sign screen printed on the flap. These onesies can be worn as pajamas or loungewear. Men or women can also wear these as one piece long john underwear or thermal underwear. Lighter than the original wool union suits, these jersey cotton onesies are more like your favorite t-shirt, but (no pun) they still have the convenient drop seat, also referred to as butt-flap, bum-flap, access hatch, fireman's flap and trap door.

Review: True to size! - This is a great onesie. Not great if your man is usually cold throughout the day. I bought this for my man, so he can wear it for my birthday party. He’s usually a M, but with desertcart I usually order him a L. I should have ordered a M, because the L was a bit baggy. This is DEFIANTLY true to size!
Review: Very comfortable and well made. - I gave these as gifts to friends that live back east and they really liked them. They wanted to know where they could get more.

*by P***L on November 25, 2017*

Love how it's fits haven't washed yet to see how much it will shrink but compared to some other union suits this one fits n feels right. Hard to judge sizes. Wish the rear flap had classic buttons instead of Velcro. And wish there was options for other sayings on rear flap
