Why do women just like you just love Undersummers?

These are super comfortable. They're cool, and they do wick well so things don't get too humid, which is really nice. I also appreciate that the seams are not anywhere I sit, or that would rub; it's really clever, and it makes these great for when I'm out and about on my bike.


How do Shortlettes work?

Our fabric wicks away moisture & is lightweight to keep you dry and cool.

The seamless inner thigh reduces friction points & eliminates holes between the thighs producing a comfortable barrier of protection.

Our thoughful designs stay put while walking and don't roll down all without squeezing or uncomfortable silicone strips adding to their exceptional comfort.

What makes us different?

Thoughtfully designed with a woman's body in mind, our Shortlettes are more than a slipshort or boxer brief. They are your new favorite everyday undergarment.

More surprises than expected

The sizing guide only gave waist and hips, so receiving mostly tops was unexpected and consequently all were ill-fitting. Other items had defects in their sewing. I would not recommend this “mystery” to anyone.

My mystery box only had 1 item I could use - a nightgown The other 4 items included thong panties , a control brief, leggings in a horrifying color & I can’t recall the final item. I love the shortletts and have bought between 20 - 25 pair so I was just really disappointed when there was none in my box.

Learned my lesson.

Only one item in the box was appropriate for a 70 year old who is overweight. One of the items was about four sizes too big and how many 70 year olds wear a thong as panties? Never again.

How I bought a thong for $100

I suppose this is mostly my fault, because I genuinely didn't realize that Undersummers was not a one-trick pony. The only thing I have ever ordered from them or seen them advertise at all is the shortlettes, which are expensive but really useful and I haven't found any equivalent product, so when I ordered the mystery box, I expected five shortlettes for $95. That's a steal! I figured there would be some unpopular colors and maybe some wouldn't have pockets, but it would be worth it considering that I'm replacing my whole wardrobe after losing weight and my old ones don't fit. When I got my box I was amused and horrified by its contents: the ugliest neon snakeskin print leggings ever to exist on God's green earth, a sleep Cami that was incapable of holding my boobs, a weird, ill- fitting top, something else I can't remember because it got donated weeks ago, and a purple thong which was just meh and I would pay like $5 for it at Target. Since it was the only thing that fit, I kept the $100 thong, I still have no shortlettes that fit, and I have learned my lesson about the mystery box!
