I started with a 4" budget belt that I still use for squats. After some experience and research I got a 2.5" Best Belt powerlifting belt. It made a world of difference for my deadlift. I'm 5'11" and the 4" belt dug into my ribs which made it extremely difficult to breath between DL reps. The 2.5" allowed much more comfortable breathing. I plan on adding a 4" Best Belt athlete belt soon. Their belts are broke in when they arrive. The fit & finish is very professional. The belt edges are rounded and will not dig into you.

Okay thanks. I'll check them out! I'm not sure I under stand. How is the 10 mm with suede the same as the 6.5 without? I'm a novice at this.
It's the same in that they both have the same thickness of leather (6.5mm).
The 10mm one has suede either side of the leather (~1.5-2mm) that doesn't add support but does offer more comfort.
If you want more details on the various differences check out the general leather craft thread, I spent bloody ages reading through the whole thing and several other thread and then summarised the options in a post, which I think is now second from last page.
The 6.5 is a single layer of leather with no stitching (I own one...love it!). The 10mm adds suede and stitches them together to gain thickness.
I happened upon this post by Matt from GLC today so thought I may as well share as it's pertinent (he's replying to a comment under a video on his website):
You have the basics down there already! If you just think of TOTAL THICKNESS and then add the thickness of the other material (suede) then you will really start to get a feel for what we do.
[I]13mm double suede belt is two pieces of leather (4.5mm each for a total of 9mm) + two pieces of suede (2mm ea for a total of 4mm) = 13mm
13mm Non Suede belt is two pieces of leather at 6.5mm each
10mm belt is a single 6.5mm piece of leather + two (2) layers of suede at 2mm each = 10.5mm +/-
Deadlift Belts, Training Belts, and basic Power belts are all a single piece of leather measuring right around 6.5mm thick
Hope this is what you were after![/I]
