Rio II Nasal Pillows Interface by 3B Medical

Overview:

The Rio II Nasal Pillow Interface is light, flexible, and quiet.  Weighs only 2.3 oz making the Rio II one of the lightest CPAP mask on the market. Nasal Pillow size Small, Medium, and Large included.  Optional separate headgear availble to make mask complete by selecting add on above. 

Features:

The nasal pillow snaps into place for easy removal or change.  This feature also allows the use of different nasal pillow sizes if needed.  The mask frame has a unique vented rotating ball in socket swivel giving you a full range of motion and ideal for any sleeping position.  The minimal and ergonomic design of the Rio II Nasal Interface allows an open light of sight, ability to wear glasses while on, and only requires two adjustment points on the headgear.  Soft sleeves cover the cpap mask frame that touches the cheeks for added comfort.  Once you properly fit the headgear, it can easily be slipped on and off your head without having to further adjust making it one of the simplest CPAP mask to use.

Very good product
Size: Medium, Color: (001) Black / Black / Pitch Gray
I purchased these to wear inside lowcut slip on casual shoes, I don't particularly like to not wear socks in my shoes for hygienic reasons. Prior to purchasing these socks, all I could find were those made of very light beige hosiery type material , and my slip on shoes would slide around a bit. These are light weight and breathable athletic type material, with a very good gripper strip at the heel. One pair of my slip on casual shoes have a particularly lower cut in the toe area, but the shoe is black and I chose the black color and though I see a hint of the sock there, it matches and does not detract from the look of the casual solid black shoe

They stay out! No more sock wads!
Size: Medium, Color: (100) White / White / Mod Gray
Best no show socks ever made!!!!! I've been struggling for 2 years to find ones that actually stay on your foot, even other national brands, and I just became content wearing my sneakers without socks. They ALWAYS slid down into my show & I ended up walking on a wad of sock until I could fix it...or usually just took them off after a couple of tries. Enter Under Armor!!! They a mid weight, but not very thick & still breathable. They work too by actually staying on your foot! Not once have they slid down into my show!! Very comfortable but they could be a little more affordable.

Ive tried so many no show socks but I love these. This is the 3rd set I've bought. They never slip off and the material is thin and breathable. Perfect for working out.

True no-show socks that don’t slide down!
Size: Medium, Color: (100) White / White / Mod Gray, Size: Medium, Color: (100) White / White / Mod Gray
This is the first pair of no-show socks I’ve tried that actually don’t slide down into my shoes. Trust me… I have tried lots of different pairs and this is the one! They fit perfectly. They’re not too thick and they’re obviously durable because I wash them after each wear, so daily.
