I recently purchased the Forever Lazy Heavyweight Adult Onesie and I have been absolutely loving it! This one-piece pajama jumpsuit is the ultimate comfort wear for both men and women, and I can't get enough of it. The onesie is made of a heavyweight, high-quality material that is incredibly soft and cozy, making it perfect for lounging around the house on lazy days or for a comfortable night's sleep. The design is unisex, so it's suitable for anyone looking for that extra level of comfort and warmth. I particularly love the practical features of the Forever Lazy Onesie, such as the zip-up front and spacious pockets that are perfect for carrying essentials like my phone or remote. The hood adds an extra touch of warmth and coziness, making it ideal for chilly evenings. The sizing options are great, and I found that the onesie fits true to size, providing a comfortable and relaxed fit without being too baggy or too tight. The quality of the material and construction is evident, and I can tell that this onesie will last me a long time. Overall, I highly recommend the Forever Lazy Heavyweight Adult Onesie to anyone looking for the ultimate in comfort and coziness. It's a versatile and practical piece of loungewear that has quickly become a staple in my wardrobe. I can't imagine my lazy days without it!

I freakin' LOVE these pajamas!!! LOVE. They are heavy, soft, comfy, roomy and amazing! And the pocket in the back - perfect! For those of you that live in a house that is always freezing, or go camping a lot - you've got to get these. Mainly for the fact that the back pocket makes life soooo much easier and warmer when you have to go to the bathroom. I am mostly talking to the women out there - you do not have to pull the whole outfit down and freeze to go pee! You just unzip that back pocket and wallah - you are in business! It's huge so you won't have any accidents! Bathroom Pocket + Warmth when going to the bathroom in cold environments = THANK YOU FOREVER LAZY!!! Get this if you love comfy, warm jammies! I will say that you won't want to sleep in this - unless maybe if you're camping, but at home, you will get hot. You can wear jammies under it or something like t-shirt and undies (unless you just like sleeping naked!), so you can strip the onesie off before bed. Also, it will shrink a bit in the dryer - mostly length wise, so when you first put it on, it will be long and drag on floor, but that first wash should bring it up quite a bit. I am 5'4" and I have the xs. I can also fit in the xxs but the xxs is a little snugger than I like. I also like the way the S fits on me, so it just depends on how roomy you want it.

I like my pajamas very much but! They run a lot larger than I’m accustom to. So when you purchase these heavyweight pajamas, unless you like extremely loose pajamas. Go back one size. They are footless pajamas that are long enough, and loose enough. I weight 189 and 5’5” and I got a size medium. Seeing how lost I was inside of these pajamas, I would have got a size small. I’m going to keep this medium anyway and was them in hot water and dry them and hope they shrink a little. But next time I order these pajamas in a different color, I’ll know what size I need. Just one last thing, the warning tag on the pajamas got my attention immediately. It says: At any time while wearing this product you start experiencing feelings of energy and/or ambition please seek medical attention a.s.a.p. So I hope I don’t experience none of this while I’m sleeping.

I Highly Recommend The Heavyweight Forever Lazy! I own other fleece Forever Lazy PJ's and this is my first time trying the heavyweight; I am a FAN! I love my fleece (lighter weight) Forever Lazy and the Heavyweight Forever Lazy is beyond my expectation. The material is an extremely comfortable and soft sweatshirt material that is much warmer than the fleece version. I can not state enough positives about this item! It is certainly worth the money. The zippers open at each end and glide with ease! The pockets are very large; yet, not bulky or noticeable by others. I am almost 5'4" & 125 lbs. I normally buy a Small/Medium in the fleece version and chose Small this time for the heavyweight. I could probably easily fit the XS, but enjoy the extra space (intended purpose in wearing an adult onesie - lol)! The arm-length in the small is perfect and I easily rolled the bottom of the legs to make a cute cuff. If you aren't sure if the Heavyweight Forever Lazy is worth the money or much different than the fleece version, I highly recommend it! Please do not misunderstand me, I still love the fleece version...but will save them for warmer months...the Heavyweight really Packs-A-Serious-Punch in more ways than one (all good ways, too)! I am so glad I bought this one for my self and bought another in a different color to give as a gift! Forever Lazy's fleece and heavyweight onesies are amazing! I will certainly be a repeat buyer of the heavyweight version now that I have tried it. I sew and embroider so I can state from experience that the Heavyweight Forever Lazy is great quality and a great deal! I hope my review was helpful! Please take good care! :>) P.S. Only issue to warn about is...once worn, you may never want to wear any thing else!

I ordered it too big. I’m used to sizing up since I’m 5’9 and I’m over 200 pounds. BUT It’s really comfortable, pockets are deep and I love butt flap. The legs are really long so I’m gonna have to wear some heeled boots.

I got a one piece pajamas, or a jumper because I am so tired of my pajamas riding up on me when I sleep and this was causing me to be cold at night. I had one of my best sleeps in a long time last night with this. Even though the legs were not tight around my ankles, the legs did stay down and did not ride up on me. Warm!! Love the hoodie! Zippers in back perfect for night time bathroom visits. Sized large but I like that also!
