Depending on how loose your scrubs are , haha. Some of the most discrete options i have used are: LG's ADS, it is a very piece that just touches over the tip and is concealed within a sleeve. lghangerllc.com/product/ads-wvelcro-leg-strap/
next would be autoextenders ADS - autoextender.com/usorder.html
this piece fits around the head. I sometimes felt this eas more comfortable. But I also alternated.
NOTE: I did not like the cumbersome nature of this product and sucking air out. Some did not mind, I did. So, I swapped out the glans cover with the cheap glans covers from ali axpress - also found through Total Man for more money. totalmanshop.com/collections/full-kits
these have a medium sized suction device that you can keep in your pocket if it fits.
- again, you basing the device you use each day based on what you wear.
Last, the sili stretcher from MOS is pretty good, i use it a lot. BUT, its listed last here because it is thick than the rest. But, for me, the convenience of having the twist top makes up for it, but i do wear looser pants ( Sweats mostlty ) when using this one. shop.mattersofsize.com/products/silistre...er-and-weight-hanger
