At first sight, we were intrigued by the Under Armour Pure Stretch Hipster. Its nearly seamless design and ridiculously thin and soft material set it apart from the competition, and we weren't sure how it was going to perform. After weeks of testing, we found it to be comfortable and quick-drying. However, our testers couldn't agree on the fit. We like its style, however, and as one of the lightest pairs of undies we tested, we had no qualms awarding it for the value it provides. It may not have excelled in any single category, but its solid performance across all our test metrics at a bargain price has us giving it two thumbs up.Editor's Note: As of January 6, 2022, you may not find the pink color that we tested online any longer, but this pair of undies is still available in several color options. Though we snagged an individual pair for our initial test period, the Pure Stretch Hipster is now only offered in a 3-pack, which reduces the price per pair.

Our Analysis and Test Results
The Pure Stretch Hipster is nearly half the price of many of our favorite products. And with exceptionally lightweight and quick-drying construction, we found it to be a pretty great buy. Its soft material had us reaching for it morning after morning, and at such a great price, we're sure to be stocking up.
Here at OutdoorGearLab, we sometimes let ourselves get carried away with performance. We count ounces, do rigorous testing, and meticulously weigh the pros and cons of everything we test. We pride ourselves on this commitment, but when it came to underwear, we were forced to relent. If your underwear isn't comfortable, the other metrics don't matter.
Fortunately for us (and you), the Under Armour Pure Stretch Hipster is mind-blowingly comfortable. Constructed with a nylon/elastane blend and a cotton gusset, our initial impressions of this product stayed true no matter how long we wore these undies. For next-to-skin softness, this is a great pick.
The material of the Pure Stretch is incredibly thin, and the lack of seams along the leg openings or waistband made for a smooth (and panty line-free!) fit. We loved wearing these undies under leggings or yoga pants for this reason. We also found the thin material to aid in breathability, and although there were others we might pick for super hot weather, we found the airflow to be adequate.
The Pure Stretch was the only pair of undies we tried with a cotton gusset. This is the only part of the product that isn't synthetic, and while not great for odor control, this could be a winning feature for buyers whose bodies require some cotton.
To adequately detail all the different ways these undies felt on our bodies, we separated "fit" from "comfort".
For this metric, we looked at sizing, waistband, stretchiness, and, of course, the dreaded wedgie. Overall, we found the fit of the Pure Stretch to be above-average but still not our favorite.
The coverage is decent but not exactly modest on this product. The leg openings are relatively high, giving us the occasional wedgie despite the attractive cut. To maintain this "seamless" look, the only seam is located along the butt crack, which was not one of our favorite design features, though it wasn't too noticeable while in use.
The Pure Stretch is, just like the name might imply, super stretchy, making this an excellent choice for activities that require our full range of motion. Whether running or practicing yoga, these undies were anything but constricting. While the Patagonia Barely Hipster has too-tight legs and the Smartwool Merino 150 a too-tight waistband, the Pure Stretch is essentially an elastic band, guaranteed to keep up with all your crazy movements.
Nothing puts our clothing to the test like traveling across the world and hiking into the Andes, but sometimes we need a good old-fashioned experiment to level the playing field.
For our drying time test, we took every pair of undies in this review, soaked them in water, and hung them side-by-side to dry in the warm California sun. The lowest-scoring models took more than an hour and a half to dry, while the fastest we could put back on in less than forty-five minutes.
The Pure Stretch was one of those winners. Completely dry in just 42 minutes, this metric boosted this product's overall score. We're more confident than ever that we could easily rinse these undies out in the sink of our hostel or in an alpine lake and put them back on the next day. Another model that dried in similar time was the Smartwool Merino 150 Bikini. If you're willing to pay a steeper price, we'd enthusiastically recommend that model.
When measuring tents or sleeping bags, we're often discussing pounds of difference, a metric that really changes our enjoyment while traveling.
We wanted to discuss weight differences in undies, too, but we do want to issue a reminder that the difference between our heaviest and lightest undies was just over half an ounce! So while ounce-counting may be one of your favorite hobbies, we recommend using this metric as a secondary test to the first three properties we discussed.
All that aside, at .7 oz, the Pure Stretch Hipster is lightweight, giving us the ability to pack two pairs of these undies for the same weight as one of the heavier models. The thin, stretchy material stuffs easily into a backpack or suitcase space.
The Pure Stretchis a third of the price of some of the other products in this review. This product is comfortable, stretchy, and soft. It fills the basic requirements of women's travel underwear, without overwhelming in amazement or price. Because it works just fine and costs much less, its value is high.
While the Under Armour Pure Stretch Hipster didn't take home the very highest overall score, we were impressed with the value offered. It was more comfortable and faster to dry than many of the higher-priced contenders. We'd happily recommend these to anyone intrigued with synthetic underwear but who isn't willing to shell out a dinner's worth of cash. That being said, if the fit is paramount, we would look to our other award winners.
