Top Of the Shoulder (TOS) Counterlungs for Inspiration/Evolution CCR

Clutter-free chest with TOS counterlungs.

Best of both words: clean chest like BMCLs, with manual Add valves and ADV in easily reachable postion on your shoulders.
T-pieces included - fit Ispo/Evo hoses
You need add HH MAVs and ADV (will not fit AP MAV and ADV)

  • excellent work of breathing, T-pieces virtually in the same place as OTS CLs
  • Counterlungs are in front of the wing, as close to lung centroid as possible
  • ports for high quality manual add valves with tactile differentiation between Oxygen and Diluent valves for low vis operation
  •  port for plunger style ADV
  • attached with Fastex releases for easy removal. Adjustable in the front and back for precise positioning
  • two sets of Velcro loops on underside for precise routing over the shoulders
  • built-in weight pocket
  • dump valve at the bottom of exhale lung for flood recovery
  • rock solid construction
    • Cover: Outer abrasion resistant shell made from Cordura 2000
    • Bladder : inner bladder made from RF welded CORDURA 560 with PU coating. It resists hydrolysis, low temperatures, and hydrocarbons.
  • NO  OPV

This is an advanced experimental counterlung system. Do not use if you are not comfortable diving without OPV
