What are the differences between Watercell ST and Watercell X?

Both the Watercell ST and Watercell X are made from EU food-grade, BPA and PVC-free materials.

Both have RF (radio frequency) welded seams and an internal baffle that keeps their rectangular shape even when full – making them perfect for stacking!

Both models also include a welded fill handle and multiple lash points for carrying and securing.

Key Differences

Materials & Durability

• • Watercell ST: Made from TPU film  rugged enough for backpacking. Semi-translucent with printed fill lines on the exterior.
  • Watercell X: TPU film laminated with 400D nylon that's stronger, but heavier.

Attachment Points

• • Watercell ST: Die-cut grab handles on the sides.
  • Watercell X: TPU straps running around three sides for added versatility.

Cap & Functionality

• • Watercell ST: Simple 63mm screw-on cap.
  • Watercell X: 63mm screw-on cap with removable internal spigot. Includes an optional mini showerhead attachment.

Which one should I choose?

If you are backpacking, the lighter Watercell ST may well be your choice. If you are paddling, car camping or overlanding (especially if you want to convert your water storage into a shower), the Watercell X is probably the better option.
