Final answer:
The excess straps on the LPU-38P are secured using hook and loop fasteners (Velcro).
Step-by-step explanation:
In the LPU-38P, the excess straps are typically secured through the use of a hook and loop fastener. These fasteners, commonly known as Velcro, consist of two components: the hook side and the loop side.
The excess straps are looped through the hook side and pressed against the loop side, creating a secure and adjustable attachment.
