title: Forever Lazy Detachable Feet Adult Onesie - Lavender - M
text: Product Description Forever Lazy Adult Footed Onesies Have you ever been labeled a "ball of energy," or even worse, a "go-getter?" Well don't worry because these 100% polyester, super soft, anti-pill fleece onesies will put you, and those labels, to rest. Once you slide into the cocoon of coziness known as the Forever Lazy, nothing, and I mean nothing, will be accomplished as long as it is worn. Forever Lazy Size Chart Our onesies are different from other onesies on the market in that they are sized to be really big and baggy to maximize lazy lounging. So wherever you fall in the size chart you will get a very baggy and relaxed fit , we recommend sizing down if you want a more traditional fit. Our onesies are unisex, so for men our size chart generally runs true to size, however for women our onesies run about a full size bigger than traditional sizing so we recommend sizing down if between sizes. Forever Lazy Detachable Feet Onesies This Forever Lazy onesie comes with detachable, zip-off feet for maximum versatility. The zipper tract is covered by our super soft fleece fabric to prevent any contact between your ankle and the zipper itself. Our detachable feet onesie is great for lounging around the house and keeping warm from head to toe without needing to wear slippers or socks. However, if your feet get too warm simply unzip the footed portion to remove the footies. Forever Lazy Product Features All of our onesies feature a rear zipper concealable drop seat...so you never have to take it off. The zipper tract is concealed by a small flap of fabric. All of our onesies feature a double pull front zipper. This allows guys to be able to unzip from the bottom up so they don't get a chilly chest when nature calls. All of our onesies feature deep side pockets. The pockets have been engineered to hold three 12 oz beverages each.
