How it surfs
The 4/3+ notation refers to the thicker torso panel — 4 mm through the chest and back, 3 mm through the arms and legs, with a slight extra torso thickness for warmth without stretch compromise.
Owner feedback consistently praises the balance: warmer than a 3/2, more flexible than most 4/3 winter suits, and easier to get in and out of than a zip-free.
