It doesn't slip but when I sit down the strap presses into the buckle causing the buckle to fall out every time which is really uncomfortable. The belt fell apart completely after 3 weeks of use. Complete garbage.
Pros
NO HOLE REQUIRED: This strap's ratcheting mechanism eliminates the need for traditional strap holes for a more precise and secure fit.
Cons
May not be suitable for those with large waist sizes due to limited length options.
