[As BRP except Burdens: Hard Leather L (not M); Ring M (not L)]
The burden of a full suit of armour is the highest of any constituent piece. Pieces give the burden of their base BRP armour type (boots/caps one less, gauntlets/full helms one more) . Multiple layers add burdens together; over Heavy is too cumbersome to move.

Burden  Light: no skill penalty, -1 Move, +10% Magic fumble. Moderate: Skills x1/2, -2 Move, +20% Magic fumble. Heavy: Skills x 1/10, -3 Move, +30% Magic fumble. Listen/Spot skills are greatly disadvantaged in Full/Great Helm; Lockpicking, Shooting Bows and Playing Instruments are impossible in Gauntlets.  Anyone not trained to the burden of armour is automatically Encumbered.
Encumbrance 
Capacity:  SIZ x (STR + 10) / 20  (x14 lbs).  Over half Encumbers: Movement, Initiative & Dex-based skills are x1/2.
Fatigue
  Exertion (e.g. combat) for a turn requires a CONx5 roll to avoid Fatigue (Movement, Initiative & all skills x1/2) or if already fatigued Exhaustion (x1/10). Recovery from fatigue requires rest for 1 hour; exhaustion 8 hours.

Movement Rate (MOV) is 10 for Humans (Elves 11, Dwarves 8, Halflings 6), being the number of 5ft squares moved in a full round. Each Move Action allows half that, rounded down: i.e. MOV 10 = 5 sq./move; MOV 9 or 8 = 4 sq/move; MOV 7 or 6 = 3 sq./move; etc. Running (x3/x5) is possible for short periods if not in combat. (MOV 10 = 25ft/action, 50ft/round, 300ft/min., ~2 mph, ~20 miles/day).
