and pepper spray, and custom pouches include PALS-compatible pistol holders, hydration pouches and utility pouches. These pouches are normally secured through the use of straps, alice clips or speedclips. MOLLE and PALS The term MOLLE is technically only used to describe the specific system manufactured by Specialty Defense Systems, but is also casually used interchangeably to describe generically all load bearing systems and subsystems that utilize the woven PALS (Pouch Attachment Ladder System) webbing for modular pouch attachment (though PALS is proprietary to Natick Labs, most use MOLLE and PALS interchangeably). Derivatives based on the MOLLE attachment method (such as the Tactical Tailor MALICE clip system) have also been developed. Any system that utilizes modular attachment methods and is usable with U.S. general issue MOLLE components is often considered "MOLLE-compatible" or is called a "MOLLE" system. Increasingly, non-military manufacturers are incorporating PALS onto outdoor equipment. There are three general modes of attachment in the MOLLE arena; the "Natick Snap", which uses a polyethylene reinforced webbing strap with the 'pushthedot' snap fastener for security; the polymer "Malice" clip, developed by Tactical Tailor as an alternative to the Natick Snap concept, which interweaves like the Natick Snap but terminates in a semi-permanent closure that requires a screwdriver or other flat-tipped object to disengage; and a variety of attachments that fall into the "Weave & Tuck" category, in which the end of an interwoven strap is tucked into an item's backing after attachment to a vest or pack (Paraclete's SofStrap and Spec Ops Brand's hybrid attachment). The PALS grid consists of horizontal rows of webbing, spaced 25 mm apart, and attached to the backing at intervals. Although the specification is for the stitchings to be spaced apart, stitching in the range is considered acceptable in practice. Evolution and criticism The MOLLE system was introduced in 1997. However, it did not see widespread issue until after the September 11 attacks in 2001, and was used by U.S. troops serving in Afghanistan and Iraq. Early criticisms of the MOLLE system emerged, particularly from the Army. Many of these criticisms have centered on the sustainment-load pack and frame, due to the external plastic frame being too fragile and subject to breaking in the field (since mitigated), that the zippers have a tendency to burst when stuffed full and that the pack's straps lack sufficient length to be used with bulky body armor.
