    Comfortable women’s top, excellent for nursing!
    Color: Black, Size: Large
    I needed a new breastfeeding friendly tank top as I am postpartum and gained some weight. This is so comfortable and easily accessible for feeds. I wear it around the house and to sleep in. At a fraction of the cost of the more expensive brands nursing tops, this is a great practical, comfortable buy. The material is thick but breathable and not restrictive and non see through. Sizing is spot on. I am 5’4 and 160 lbs and I bought a Large. Overall this is a durable piece that is a staple in my postpartum wardrobe.

    Great top for summer!
    Color: Navy Blue, Size: Large
    I bought one of these. The v-neck and fit of the tank top is amazing! Flattering! I loved it so much I ordered two more. Great summer tank! Washes and dries fabulously as well. I am 5’4” 150lbs, wear a medium or size 8-10. I purchased a large and love the look. It fits well, not too tight but hugs the body. Not oversized.

    True to size & color, modest cut, fitted style
    Color: Purple, Size: Small
    The cut on these tops are perfect. It's a nice v-neck without being revealing. Thick straps and solid back so your bra doesn't show. Sizing is accurate in my case. 5'6" 130lbs chest 34" waist 26" hips 39" and I ordered the small which is fitted on me. I ordered the lavender purple and a black one and both colors are correct in shade. Soft and stretchy material. I air dry them mostly and only gentle low on the dryer if needed and have not had any shrinking.

    A Diabetic Traveler's Best Friend at the Hot Springs!
    Size: 13-14 Women/12-13 Men, Color: Black-w001
    I'll be honest — I bought these almost last minute before heading out on vacation to the Hot Springs in Carson City, Nevada. As someone with diabetes, I have to be really careful about my feet, especially on rough or hot concrete surfaces. Pool decks and spa areas can be brutal, and I've had too many close calls just walking around barefoot. I grabbed these water shoes almost as an afterthought, and they ended up being one of the best decisions of the whole trip. From the moment I slipped them on, I could tell they were going to do the job. They fit true to size — no awkward sizing guesswork — and they hugged my feet snugly without feeling restrictive or causing any pressure points (a big deal for me). The sole gave me just enough protection from the concrete and wet surfaces around the springs, and I never once felt like I was going to slip. That peace of mind alone was worth every penny. They're lightweight enough that I barely noticed I had them on, and they dried quickly after getting splashed or submerged. No heavy, waterlogged feeling dragging me down. I wore them in and out of the water all day and my feet felt totally fine — no soreness, no irritation, nothing. For someone managing diabetes, that's honestly huge. I genuinely have zero complaints. These delivered exactly what they promised and then some. Whether you're headed to a hot spring, a beach, a pool, or just doing some light water yoga, these are a solid buy. Hope this helps!
