Panniers are containers that hang from the pack saddle, one on each side, so the load is balanced across the animal: keep each under 35 cm wide so they do not catch on trees and rocks, and keep the pair within 2 kg of each other. Use rigid panniers of wood, basket or plastic for fragile items and produce, and soft panniers of canvas or sacking for loads that cannot break.

Side-loading containers for pack animals: the two families, the width limit and the balance rule that governs both.

Panniers Turn A Load Into Two Balanced Halves

A pannier pair divides the load into two matching halves, one on each side. That is why two equal containers beat one large one: equal weights hold the saddle square, and a narrow container clears the trail. The container type decides what it can carry; the balance and width rules are the same for both.

What You Need

  • A pack saddle with hanging points — the arms of a sawbuck or the pommel and cantle of a modified riding saddle; see Pack Saddle Design.
  • Two containers of matching size.
  • Hooks, loops or straps to hang them.
  • A scale or balance — to weigh each side. See Logistics & Load Planning for ways to weigh.

Method: Specify A Pannier Pair

Step 1: Fix the width limit. Under 35 cm per side. Wider panniers catch on trees and rocks.

Step 2: Choose rigid or soft. Rigid for fragile items; soft for loads that cannot break and for tight trails.

Step 3: Make the pair matching. Same size, same hanging height, so the saddle is level.

Step 4: Weigh each side. Maximum difference between the two: 2 kg.

Step 5: Check height and clearance. Hang so the bottoms clear the ground and the animal’s legs.

Worked Example

A large mule, comfortable load 60-70 kg per the source table, with a pannier pair.

  • Per side, comfortable: 60 / 2 = 30 kg to 70 / 2 = 35 kg.
  • With a maximum 2 kg difference, a 70 kg load splits at worst as 34 kg and 36 kg.
  • Check against the width limit: with two panniers each under 35 cm wide, the total width added to the animal is under 2 x 35 = 70 cm on top of the animal’s own body width.

The source gives no allowance for the weight of the saddle and panniers themselves; weigh them and count them in the load unless the animal’s allowance says otherwise.

Common Mistakes

  • Panniers wider than the trail allows — see Trail Hazards.
  • Unequal weights — the saddle rotates.
  • Loading the heavy item at the top — see Weight Distribution Rules.
  • Hard corners on the animal’s side — pad them.

Safety

A pannier is a moving obstacle

Panniers swing and catch on trees and rock; a snag can spin an animal or push it off a narrow path. Keep them under the width limit, check hanging loops before each day, and never hang a pannier so the animal cannot be freed from it quickly in water or after a fall.
