Patagonia R5 Wetsuit Booties

Patagonia boots are made of high-end Japanese superstretch neoprene for an amazing flexibility in the water. The exterior is made of smoothskin to deflect wind, and the interior is merino wool lined for superior warmth, and moisture wicking. Seams are sealed to keep cold water out. Fine grip sole provides traction without sacrificing dexterity.

7mm boots are generally appropriate for 35-40 degrees and up

Patagonia does wetsuits differently. They stand behind every product with a lifetime warranty (does not cover wear and tear, of course.)
