I got the G Gradual womens joggers pants with zipper pockets tapered running sweatpants (polyester blend), in two sizes medium and large. I kept both sizes. This is a medium to heavy weight fabric. The pockets are plenty big for my iphone. The zippers are high quality. Not like the PULI brand joggers i just returned because the zippers were cheap junk. The G Gradual are very stretchy polyester spandex biker short/ swimsuit material used in leggings. This is for all you petite ladies. I am 5”1’ tall and 110 pounds. These are very high waisted on me. But the maybe just mid rise on people who have a longer torso. My hip measurement is 37.0” and my natural waist is 26 inches. Two inches above my belly button is 28 inches. My belly button circumference is 31 inches. When I am full of food or bloated my waist bloats to a 32-33 inches. Hence the size large is a must for comfort. I measured the elastic waistband of the G gradual pants in size large and medium and compared them to my collection lulu lemon, hey nuts, under armor, old navy and crz yoga shorts and joggers that I own. The take home message is the factory cut the waistbands one size small. I measured and compared them to ones I own. The G gradual fit true to size every where except the waistband. So if you can only afford one pair, size up one size from your normal size then the waist will fit you properly but you’ll have more room in the butt and thigh. The size medium’s waistband fits like a small. The size large’s waistband fits like a true medium. The size XL will fit like a large. These are made in China. I tested these here in Texas at 100 F degrees I went for a short 45 minute run. Nope. Too hot. I sweat so much that that the joggers were 70% drenched sweat. The next day, I tested these in my Air conditioned gym set at 70 F degrees. I walked on the treadmill for 90 minutes at 4mph. These did get wet again, they sop up sweat and stay wet and felt heavy. It took 2.5 hours for them to dry. The next day I tested them again in my gym Air conditioning set to 68 F degrees. For my warm up I ran 5 miles in these in my air conditioned gym set at 68 F degrees. I was pretty hot but comfortable enough and the fabric got wet again. I did not have any sweat marks. But that is probably because they were black. I did high knees, dead lifts and squats with my phone and keys and these pants ROCK! I would not run in them if it is over 80 F degrees. These should be fine for outdoor workouts 35 F degrees to 60 F degrees. If its colder layer thermal leggings under neath. FYI, I also tested another Amazon brand this week called HAIMONT zipper joggers made from nylon blend. Honestly, I love the HAIMONT for HOT weather workouts. I ran the same workout test in the HAIMONT and I was 90-95% DRY! The nylon repels the sweat and does not soak it up like these G Gradual joggers. So I bought three pair of the HAIMONT and I will use those for my summer workouts. And I will save the G Gradual for colder Fall or Winter weather workouts. I do recommend these. I wear them inside my air conditioned house set at 70 F degrees and I do not sweat and I am not too hot. But I will save the G gradual for colder workouts. I only purchased black in medium and large so far.
