Perfect tank top
This is easily my all-time favorite active tank top. I wear it for running, hiking, backpacking, weightlifting, and just relaxing. It’s lightweight, breathable, fast drying, and offers plenty of coverage. I love that the straps are wide enough to wear with a pack. The fabric is super soft and smooth; I’ve had no chafing or irritation, even on 10+ mile trail runs. I’m super sensitive to fabric textures, so this is huge for me. And the color is beautiful! I also love that it has a locker loop so you can hang it from a hook to dry. This is a small but thoughtful detail many clothing manufacturers overlook, but it really helps with fabric care. The fit is loose by design, as are the other tops in the Sahara line, but that helps it to stay cool and breathable in the heat.I sized down because I personally prefer a slimmer fit, but I know people who size up for the heat. It just depends on your preference! For reference I am 5’6” and usually wear a size medium or women’s 8-10, but I sized down to a small for this one. It fits me very well with plenty of breathing room, which I love. I plan to buy a couple more!
Great full coverage tank
This is a great versatile tank when you need full coverage. Almost too full coverage. I found the arm holes to be slightly smaller than I’d like for gym workouts, but works well under a backpack. The fabric is light, breathable, and dries quickly. It does show sweat. It has held up well with multiple washings and shows no signs of wear. The size small fit well and ran true to the size chart.
So soft and comfy.
I liked this better than I expected to! Nice easy fit with good coverage under arms and a great length. Pulls a little across the chest with certain movements though. Super soft fabric, gorgeous color, and I’ll use for hot weather workouts but also for layering with casual outfits.
My new summer top
Love the material of this top. Great color and breathable soft comfortable material on my skin. Size M was perfect fit for me - not tight but not loose - for reference I am 5’7” 150#. Great for hiking, exercise, keeping you cool in summer heat with some UV protection.
Soft, good fit
Love this tank top - lightweight, soft, comfy for hikes, workouts. The fabric feels nicely stretchy and breathable. I like the fit and the shoulder coverage. Overall, it’s a solid casual/trail tank with a relaxed fit.
Comfy tank in the heat
Stellar workout tank! This has been my go-to for running in the warm desert spring -- and I've definitely appreciated its moisture wicking properties accordingly. The fabric is light and the cut is roomy and comfortable. Plus, the broader shoulders make it easier to apply sunscreen solo compared with narrower racerback tanks. It's a win for me!
Good, but stop changing the material!
I love these and they're my go-to shirt for qorking out and physical activity, but i wish they would stop changing the material and fit every 6 months. It's beyond annoying to find a product you love and for it to constantly change.
Silky Dark Teal day hike or date night top
Size L fits great. The shape is very flattering. I like the wide shoulder straps so I don’t have to worry about what bra I wear underneath. The color is a bit lighter online and more of a deep jewel tone in person. I am 5’10” pear shaped, small bust, wide hips. 180 pounds
Love the color and fit. Runs a bit large
Love the color. Fits well around shoulders and underarms but gives plenty of room to move. The shirt is flattering even though it has a boxy cut. I usually wear a small but xs fit better
very strange cut
Color, fabric were nice. Sometimes it’s nice to have an exercise tank with a little more coverage. But this was just cut strangely wide through the torso and hip area.
