The Guardian Fall Protection 37100 Series 3 Full Body Harness is the X-Small/Small size in the Series 3 lineup, built for smaller-frame workers who need a properly snug, safe fit that a one-size universal harness can't deliver. A harness that's too large rides up, loads the wrong points, and undermines fall arrest — sizing down to the 37100 is the point of this SKU.
Where It Earns Its Slot
Where it earns its slot: Editorial assessment by Steven Eaton, WC Safety editor, based on published Guardian Fall Protection specifications and category fit. We did not laboratory-test this product.. The sections below test that positioning against the documented configuration, not against wishful thinking.
Honest Limits
Honest limits: fall protection is system math. This component's rating assumes compatible companions, an anchorage that meets requirements, and enough clearance below the worker for the arrest to complete — run the fall-clearance calculation before trusting any height. Damage or deployment evidence ends its service on the spot.

Why trust WC Safety
WC Safety is an independent, affiliate-supported review site. It is not a retailer: it holds no inventory, takes no orders, and earns only from qualifying purchases through clearly marked links — which never changes what a product is rated to do. Standards language is taken from the regulation text directly, and ratings are reported as the manufacturer publishes them. We run no laboratory and perform no testing of our own. Where published sources disagree, we say so and plan on the conservative figure rather than the flattering one.
Our methodology
Figures come from the regulation and the published specification, in that order. Derated numbers are calculated, not estimated. Nothing here is presented as a measured result, because we measure nothing.
