I ordered the BeltAway, Jelt, and Infinity Belt to compare. Overall, the BeltAway is my favorite.

Pros: This belt really does lay flat. It is also adjustable, which is nice because my waist size varies a lot and I hate having a tight belt. The belt feels sturdy and well made.

Cons: The buckle is still slightly clunky and can poke when Im sitting down, similar to a regular belt buckle. The belt does ride up my belt loops a little so I wish it had silicone grips on the inside to prevent that.

The pics Ive posted show what the Belt Away looks like on, then a pic comparing a regular belt and the Belt Away under a shirt.
