Tie waist hardware fell off right away!

Put them on, went to tie the waist and very disappointingly, the metal end of the tie came right off as well as the metal ring around the tie hole. They don’t reattach. Not a huge issue regarding the wearability, but not the quality I expected. The material is nice and thick, but this was not great!

Super comfy!

These joggers are super comfy, have washed well, And I really like the fit. I expect them to go over gym shorts well for winter walks into the gym. For reference I’m 5’6”, about 155lbs, and got a large.

Soft comfy and flattering

Soft, comfy and flattering. I love these joggers. I did need the size L and I seem to be size L across the range. (I wear dress size12). These joggers have washed really well, as has the matching hoodie. I wear them for casualwear, yoga and winter walks/runs. I wish they were available in more colours. Defo a more winter weight fabric.

Soft Material and made for tall woman! Love them

Soft material, a little tight in the calves area - I have big calves also lol - I would recommend an extra size up - I am 5'10 and I usually have issues with the bottom of the joggers, these were a great fit. Highly recommend.

I absolutely love these

I absolutely love these. The material is far thicker than I thought it would be which was indeed an very pleasant surprise. The inside of these are extremely soft and feel amazing on my legs. The fit is really good as well, I usually have a hard time getting things to fit properly since I am rather tall. But the length on these are perfect as is the comfort level of the leg width. They aren't super baggy but they aren't skin tight either. So glad I got these and will be using them often. Love them!

They are not "slim" fit, but VERY comfy

They are not "slim" fit, but most definitely regular fit. I have had slim fit from Just Strong before, which they don't do anymore.
They are VERY comfy, i have yet to wear them to the gym as I have been wearing them around the house.
If there were different colours available, I would buy more.

I love the pants

I love the pants, however, there is not much give or stretch in them. They could be more comfortable with slightly different fabric.

The quality good but overall too big

The quality of the material is good and the joggers are soft. However, the width of the legs is bigger than I had expected. I typically wear a size M but these are way too big on me. I would like to return them for a smaller size and see if it’s a better fit, but the cost of having to return them potentially multiple times is a deterrent.

Jogger love!

Super comfortable! Great for wearing to the gym on cold days or just hanging around the house. They ran big on me, but the drawstring makes them wearable regardless.

Mixed Feelings

They are quite large. The material is nice and thick and feels durable. I wore them and washed them only once. One of metal covers that caps the tie around the waist came off.

The pants are super soft and thick but thats about all they have going for them

The pants are super soft and thick but thats about all they have going for them. The drawstrings are to short i bought a 2xl and they are baggy in the waist with a too short drawstring, tight through the hip but not in a good way, the front is tight and hard to move in but the back fits nicely. They are also more of a 7/8 length. I am 5'9 and they sit about 2 inches above my ankle. I really wanted to love them and if im not doing anything active and just hanging out on the couch they are good but there is no way I can workout in them or really feel comfortable wearing them out and about.

joggers is nice

The material of the joggers is really nice, but the amount of fabric between the waistband and the crotch is huge. They fit tighter in the upper section and don't sit just right with all of the extra material
