I own two of those cool looking guitar straps, mostly attracted by the worn looks. I wasn't familiar with the brand, but the strap turned out to be extremely comfortable with the soft padding. The cushion adheres to the clothes nicely and gives an impression of you and your gear being one thing. The strap doesn't produce any slippage nor movement even while playing dynamically, whether we wear t-shirt or jacket.
The only complaint is that the strap itself is quite stiff and doesn't fold as nicely as straps made from other materials. However, most of the time I managed to put it into the gig-bags or hard shells on top of the guitars without much problems.
The length adjustment should be enough for guitar players. 150 centimeters is the limit. However some bass players may look into dedicated bass strap from the same vendor due to the increased width of the strap by 3 centimeters. There are only 3 holes in the strap, separated by a considerable distance, so without a proper adjustment one may end up with the rest of the strap hanging annoyingly.
I played with the strap with and without strap-locking systems and I didn't have any issues with the strap unlocking. This may be due to the fact that the straps are relatively new, some other reviews may have impressions after years of usage when the strap attachments are considerably more worn.
The price makes this strap a clear winner, for this comfort level and cool looks it's not easy to find a viable alternative. Color spectrum may be limited, but the worn styling may be appealing for vintage guitar players. The fact that the strap doesn't just hung on you, but rather hugs you gives a slightly more immersive playing experience. However, guitar spins might be difficult with this strap if you are into those tricks.
