Mixed results

3 of the 10 fell apart before I even wore them. I emailed Undersummers but didn’t hear back. (i haven’t worn them all. I tend to wash and reuse the same ones). The ones I have used are comfortable. I love the tie behind your head style. I don’t like the behind the ears straps.

Good masks

The masks fit well and I like that they have the metal wire for adjusting at the nose. They shipped quickly too! The straps are super long and my cat kept trying to play with them as I thumbled to tie them around my head, but I found I can tie them around just my ears and cut them. The mask stays in place better that way and I can't be tempted to pull it under my chin. Long straps could be good for fitting around various sizes and shapes of heads though. I was a little disappointed by how much moisture stuck to the masks - it's 90+ degrees here so it's hard not to sweat with a mask on your face. After a half hour walk, the mask was starting to climb to me from the moisture.

Comfy mask for short faces

The fabric is really comfortable, and I love that they tie behind the head - no pulling on the ears. The drawback is that they're only about 5 inches from nose to chin; this works for me, but not for any of the other adults in my family.

I love them. It was hard to find a mask that ties, vs going around your ears. Trust me when you have to wear one for several hours a day this is huge. Great quality & great price. Thank you for doing what you do. People on the front line, this means so much

Breathable and so comfortable

Have purchased several different kinds of masks over the last several months, and these are by far the most comfortable and breathable. I wish they had a pocket for a filter, but they are still well worth the purchase.

Like them

Very comfortable. Like them better than the regular fabric ones. Only drawback is no filter pocket. I’m a nurse and I wear this whenever I go somewhere in public.


Better than homemade!

These masks are WAY more comfortable and easier to breathe through than the homemade ones I whipped up using quilting cotton and desperation. The knit is really soft and conforms to my face well, and the flexible strip along the top holds it close around my nose. As of the time I'm writing this review (June 2020), there's not wide guidance about how thick the fabric on masks needs to be (or indeed whether wearing a mask really affects the spread), so these seem like a good compromise---they're easy to breathe through, but when I hold the fabric up to the light, I can't see through it, which is one standard I've seen. So, these masks keep me in compliance with my county's rules in reasonable comfort and may make the people around me safer... I'll take it!

Shortlettes are generously sized  to hug but not squeeze your curves.  They are not compression and do not feel like nylons/hosiery, shapewear, bike shorts, or compression pants.  Shortlettes are simply comfortable.  They are not made to be tight, feel constricting, shape, pinch, or bind.  The longer lengths allows for maximum chafe protection and comfort.

Correct Fit Guidelines:
✔️ Waist should not roll
✔️ Body should glide comfortably against the skin
✔️ Legs should not ride up while walking

Signs of Incorrect Fit:
✖️ Baggy crotch (too big)
✖️ Running at the seams/Wears to fast (too small)
✖️ Slides Down (too small)
✖️ Legs ride up (too small)

Which is the best fit?

CarrieRae's Recommendations:

Under 5'4" - High Thigh, Athletic, or Classic Styles

Plus Size - Fusion, Classic, or Original Lace

Apple Shaped - Fusion, Classic, or Original Lace

* Order the size in-between your waist and hip measurement.  I.e.  Waist 3X + Hip XL = Order 2X

Pear Shaped - Try them all!

Hourglass - Lace or High Thigh

Slender - High Thigh or Athletic

My Shortlettes fall down, why? Are Shortlettes shape wear? Are they compression shorts?
How are Shortlettes different than other slip shorts or bike shorts? How long do Undersummers products last? Can you let your Shortlettes Show?
