JoeFrex - 53 mm Tamper CONVEX

All "CONVEX" bases have a slightly convex surface for pressing espresso.

Why convex?

Normally, the surface of the coffee powder pressed into the portafilter does not play a significant role; whether it is flat or concave, there is enough space between the coffee surface and the dispensing group so that the water dispensed from it can be distributed uniformly over the coffee powder and pass through it uniformly. However, if a flat filter is used in the arm, or if much more than 7g (for a single cup filter) or 14g (for a double cup filter) is used, the space between the coffee powder and the dispensing group may be too reduced for optimal water distribution. For this purpose, the Convex Tamper Base can be used, as it leaves a cavity in the middle of the pressed powder, for better water distribution.

Loose fitting neck, not snug.
Size: XX-Large, Color: Dark Blue
I am 6’4” weigh @ 230 lbs and ordered a 2XL. My dress shirt neck size is 17 inches. If you’re happy with a very loose fitting around your neck, then you’ll be ok with this mock turtleneck shirt. I ordered thinking it would be a snug fit around the neck size, not hanging down @ one inch or more in the front.

Great for warm weather
Size: Large, Color: Dark Grey
Love these!! I was having a tough time (living in phoenix) and wearing a blazer. It is so hot here that you dont want to wear thick button up shirts with collars etc. T shirts are a bit informal. These are a great mix. Lightweight and breathable, but still a little more dressy than a t shirt. Look good with out the jacket as well. Great for church or nice night out.
