Dry-Line® is much more than a waterproof membrane, it is a unique lining system developed by Boreal with superior performance and reliability. Dry-Line® is exclusive to Boreal.


Dry_Line_Grafico_EN_white_lores

Dry-Line® combines the waterproof laminate Sympatex 337 professional (a Sympatex® membrane with breathable micro-fibre lining) and a leather or synthetic outer layer. Between the membrane and lining is an air space created by a monofilament pile layer. Moisture vapor inside the boot enters this air space and is ‘pumped’ out of the boot during normal walking action. This vertical chimney like movement of water vapor is a key part of what makes Dry-Line® superior to other membrane systems.

Regular membrane systems can usually only attempt to breathe horizontally through the upper materials of the boot. In most boots this horizontal breathability is severely restricted by layers of leather, synthetic reinforcements, glue and rubber pieces which all combine to greatly impede the transmission of moisture vapor. 

Thanks to the unique structure of Dry-Line® Boreal boots are able to breathe both horizontally and vertically.


SYMPATEX MEMBRANE

The Sympatex® membrane used in Dry-Line® is a polyether/ester copolymer membrane. Unlike microporous membranes this membrane has no pores to clog, so its performance does not deteriorate with use. It is also much more elastic than other membranes making Dry-Line® far less prone to puncture damage, consequently Dry-line® lined boots have much better long-term reliability and durability than those with other lining systems. Sympatex® is halogen and solvent free and is fully recyclable making it the most eco-friendly membrane on the market.
