IRON RAFT Self-Build Kits come in Small (S), Medium (M) and Large (L).
All Packrafts are approximately 38cm at the widest inside point and approximately 20cm at the narrowest inside point.
Approximate Internal lengths:
For optimum performance your packraft should have a snug fit. For comfort you may want a little extra space.
To gauge what size best suits your needs, sit up square against a wall with your legs out straight.
Measure from the wall to the bottom of your feet.
This measurement will give you a rough idea of what size you will want but will vary depending on the size of your buoyancy aid, shoes/boots, use of a seat/backrest etc.
