Perfect shorts for my morning workouts

Perfect shorts for my morning workouts. I appreciate the pockets. I have purchased five pair over a few years and still have all of them, so they hold up well. Will no doubt be purchasing more, especially as they are very affordable. Most importantly, buying them helps to keep American workers working.

BEST SHORTS! Multi-use! Love the waistband and feel! I have to admit, I haven’t been a fan in working out in shorts until these! The waistband is so forgiving flattering for me! They stay put when doing squats and the legs don’t roll! They feel so late as if you’re not wearing anything and they are not see-through! I wanna get another pair! I can also see me wearing them while doing outdoor sports on the water. LOVE THE PATTERN! LOVE THESE SHORTS!

Freedom USA Performance Short

Cannot stop raving about this bra! I originally bought one for myself and loved it so much that I gifted one to a friend and now she can't stop raving about it! Highly recommend to anyone considering it.

Activloops™ 2-in-1 Sports Bra

JN

Most Comfortable Bra I've Ever Worn This is hands down the most comfortable sports bra I've ever worn. I wore it on a hike, and it was incredibly convenient to be able to tie up the sleeves when I needed to. The design is so seamless you can't even tell that feature is there when you're not using it. It's so comfortable I ended up buying another one for my friend. 10/10 for both comfort and design.

Activloops™ Sports Bra // Black Short Set

Patrick

The PERFECT Tank! This is the one! Amazing fit, superb comfort, very soft - great for a 20-mile run or hitting the weights. Highly recommend my new fav tank!

Men's SoftTECH™ Tank

Anna Pearce

Great swimsuit. Worth the price. Made in the US. I found out about WSISPORTS when I was about to spend almost $200 on a fancy swimsuit made in China. Thankfully, I did not make that mistake and decided that this high price should be better spent on US manufactured products. Quick google search gave me WSISPORTS as a result. I called them to make sure the company is legit and factory is indeed in the US. They turned out to be located in Minnesota - my state! The price was astonishingly low (compared to a Chinese-made one and even to other American made swimsuits). I got the blue one is size S (top) and M (bottom).

So far I am happy with the swimsuit. It is well made, seems durable and I like supporting the company who makes the efforts to manufacture in America (the worker on the phone told me that they allow employees to bring fabrics home sometimes and sew at their convenience - the flexibility that I also support).

I would recommend it if you are looking for a “sport” style swimwear and want to support a US company by voting with your dollar.
