This soft case is the smaller, younger brother of the Boss CB EG10, and is surprisingly well made. All the right elements went into the design. The padding is firm and thick. The balance is great. The overall weight is excellent. The straps and handles are comfortable. Your Telecaster or Strat will fit snugly without too much extra room around.
As an internationally active musician of many decades, I have come to the conclusion that it is never good for a soft case to have too much wiggle room inside. It's always better to have a good fit combined with good padding. A loose fit allows for your instrument to move around, which actually makes it easier to damage it in the course of daily usage and movements and typical transportation activities. Furthermore, it wears down the case faster.
I would go as far as to say that this case can give the M*** brand cases which cost 3 to 6 times as much, a good run for their money.
Unlike the EG10, this model lacks a top pocket. But if you're looking for something small and discreet, but which still offers the best protection a soft case can offer, this is probably it.
