This is Propper’s third new AR 670-1 boot in 2017, coming on the heels of the Series 100 Waterproof in January and a new US Army contract in April.
Built in Propper’s Puerto Rico factory, the Series 300 features a Vibram dual density rubber outsole with oil- and slip-resistant self-cleaning lugs made from V40 rubber compound permanently fused to a dedicated fast-rope slot.
The inside of the Series 300 is lined with a comfortable memory foam insert wrapped in an antimicrobial fabric cover to help reduce odor buildup.
The upper is constructed from USA-sourced flesh-out cattle hide, mesh, and Dri-Lex moisture management lining bound by quadruple stitching in stress areas, all tied together with a US MIL-SPEC speed lace system.
