This is the best thing I have ever gotten from Columbia and I have been a faithful customer for too too many years. Super cute, super nice, super versatile and super comfy! Please please keep the style and add more colors and prints. The black is incredibly versatile. Great alone or with a sweater. Came back to order another for backup but out of my size.

I thought the jumper was super cute on the hanger but was apprehensive about the fit and support. I purchased a M without trying it on in the store and was very pleased with the quality and comfort of the piece. No bra necessary and I am a mother of 4 still working on my health/weight/body so it ’s nice to have something flattering, sexy, super casual and comfy all at the same time. Love this go to fit and will purchase in another color soon!

5 ChelBelle
[ The first thing I noticed when trying on the Nike Zenvy Women's Dri- FIT Bodysuit was how soft the fabric felt. I thought it would be difficult to put on, but it was easy! It fit nicely too! Not too tight and very supportive. I am small chested, so I had plenty of coverage with the higher neckline. Having had my fourth child eight months ago, it boosted my postpartum body confidence. I like to look good even when working out! I wore the Zenvy Bodysuit multiple times on my stationary bike during indoor cycling classes. My legs are constantly peddling and I intermittently ‘ get out of the saddle ’ and peddle standing up. Not once did the bodysuit shift in place. The shoulder straps stayed up and the fabric did not ride up my bum. It ’s a simple thing, but I hate having to adjust my clothing during an intense workout. Bonus: It also stayed dry while I was working up a sweat! I also loved to wear the Zenvy Bodysuit during my yoga sessions. The fabric is very flexible and easily moved with my body in every position or pose I did. I really love the design coupled with the buttery soft fabric! It also has stayed in great condition after being washed at least a dozen times by now. I was confident I would like it because the other Nike workout items I own( leggings, tank tops, sports bras) are fantastic. The Zenvy Women's Dri- FIT Bodysuit is my new favorite thing to wear during my workouts!

5 Court
[ This bodysuit fit me like a glove, I found that it was very true to size. Although it is meant to fit tightly, the smooth fabric made it easy to get it on. It almost has a compression like feel to it while allowing a nice free range of movement. I love the little built- in bra liner as it added a sense of security. Overall this is the most perfect bodysuit for yoga in my opinion.

5 JennyMack
[ I absolutely love the way this bodysuit fits! It hugs my curves in all the right places. It is so breathable as well! I went for a nice long jog and it was super cold out and it was absolutely perfect for it!

5 Ruthie
[ This Nike Bodysuit is amazing! Whether it ’s to wear it to the gym or to simply just to do errands, it ’s my go to! It ’s not too tight or too loose and it ’s stretchy! I love the simplicity of the bodysuit and how well structured it is. The material is very breathable and comfortable, I ’ m able to move around in it pretty well. The fabric feels soft and smooth and is also very lightweight, which I must say is an added plus! A lot of other bodysuits I ’ ve worn felt heavy or too tight but because of this bodysuit ’s unique design it helps out during gym sessions and everyday activities. It doesn ’ t slide down around the chest area and it doesn ’ t lift up on my legs when doing exercises. It ’s also pretty thick and is non- transparent. The only small downside could be that the bra part might be a bit small so you would have to wear a bra underneath but, overall I ’ m very impressed by this bodysuit and love how well thought out it was. I would recommend this to everyone!

5 TammyM
[ This bodysuit is buttery soft, true to size, super comfy and supportive while not being too tight. I loved that it has a built in shelf bra that had great low impact support for ample breasts. The entire garment fit beautifully and stayed put and there was no chafing from seams. This is an incredible piece for a busy gal. The leggings went all the way to my ankles and seem to be both lightweight and covered me fully without being able to see through them. I tossed on an oversized button down shirt after a light workout and it was great for a quick run to the market. The only thing that I would love to see added is a pocket big enough for a cell phone.
