Product description

The Boss B331-BK is a modern task chair upholstered in black CaressoftPlus vinyl, a soft yet hard-wearing surface that wipes clean and holds up to daily commercial use. Its lines are clean and contemporary, finished with chrome arms that double as comfortable, supportive rests during long stretches at the desk.

Underneath, a high crown 27-inch chrome base provides a stable footprint, riding on 2-inch dual-wheel nylon casters for smooth movement across the floor. The pneumatic gas lift adjusts seat height so you can find a sitting position that matches your workstation, while the spring tilt mechanism lets the chair rock and recline.

An upright locking position holds the back in place for steady support when you need to stay focused, and the tilt tension control knob located under the seat lets you customize how much resistance you feel as you lean back. The chair supports users up to 275 lb and is MAS Green certified and compliant with California TB117-2013.

Works when working outside and heavy activities
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
I use it as an Amazon delivery driver, and it works in the heat and sweat is no issue it does last for 2 hours. Reapplying it is extremely easy, no burns or sun damage to my skin. I can tell you it works cause I’m recovering from skin cancer and it works no problems or anything.

Just ok - too thick to apply evenly
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
Just ok - very thick, so difficult to apply evenly. I use this for outdoor cycling and it works, but it's so thick that it tends to clump instead of smoothly covering the skin.

Great product
I really like this sunscreen! It feels lightweight, absorbs quickly, and doesn’t leave my skin feeling greasy. The SPF 55 gives great protection, and it works well for everyday use. Great value for the price!

Delivers what it promises
I’m a fair skinned person who burns and freckles easily and in my 40’s. I also love being outside. I have worn spf on my face (and usually my hands) basically every day since I was 13 and because of that people always say I don’t look my age. Back then, only a 4 or 8 was available in face moisturizers, but I have always worn the highest that is recommended and usually face moisturizers are behind in meeting the recommendations so I have usually worn a full on sunscreen under my makeup. As the recommendations get higher it has been harder to find something that doesn’t look pasty, smell bad or interfere with makeup. I was using Eucerin spf 30 and Cera Ve spf 30 but I have wanted to increase spf to 50 because that is what is recommended now. I tried the Cera Ve spf 50 and was disappointed by how tacky it is and pasty it looks. I don’t even like wearing it alone to the beach because it’s so chalky white and sticky. Neutrogena healthy defense is alright but it has a scent and some chemicals that are not so good. It also is a pretty small bottle (1.7 oz) when you use it everyday on face and hands. But THIS product has blown me away with its affordability and quality. It IS sheer. Easily blends in and disappears quickly into skin. It’s completely odorless. It’s not tacky or greasy—you feel moisturized but not sticky. It performs under foundation even better than the Cera Ve 30. Now, this doesn’t have the extra ceramides and vitamins that does so I’ll still be using that when I feel extra dry like in winter, or I might mix the two moisturizers, but this Solimo reef safe sunscreen will definitely be my daily face and hand sunscreen in the spring, summer and early fall. These are the days I go straight from work to the garden or the beach. I can quickly reapply over my makeup before I leave the house again feel fully protected while I’m out.
