First buy. Perfect fit. Quality for 1 season? Don't think so.
Delivery was projected in 7 days; product arrived in 4 days in good condition! I matched my waist and hip size to the chart, and these jammers turned out to be snug but roomy enough to be comfortable. No bulk on the waistband or leg cuffs makes for a nice streamlined look. Compared to similar-fitting cycling shorts, I think these are easier to get used to as they have a double-layered front panel similar to underwear.
Like the color and design of these? Don't wear them to the pool for laps; save chlorine-resistant polyester jammers for that. Try wearing them as liners for surfing or beach volleyball! They will do the job of keeping sand and water from seeping into unwelcome places. Additionally, nylon is known to resist abrasion from these materials.
The fact that jammers end on the upper leg where muscle contraction is strong means that the leg cuffs can be tight or prone to sliding for some people. I've worn these over well-fitting leggings/tights and have noticed a mutual fit improvement. On one hand, the jammers no longer tightly grip my skin or slide up; on the other hand, my leggings/tights no longer sag or slide down. It looks like these jammers have enough lycra/spandex to move easily with other products of a similar blend. They might be perfect for a dance costume for those who are brave enough!
In short, you have a lot of potential with this surprisingly versatile budget-value product from Sporti. What will you do with that potential?
