What Phil Thinks...
It's a chest zip wetsuit with more than you think. That "+" means 0.5mm extra neoprene where you need it, but here's the thing, you won't feel like you're in a thicker suit, but you'll be warmer.
The biggest change: Firewalls. The TB3Air Firewall is in the chest and back - the golfball looking dimple smoothskin. You've seen it in the Psycho Tech before, but what you haven't seen is the TB Firewall that's in the thighs and all the way down the legs - it's basically a Psycho Freak, but better. While they dropped the Psycho Freak name, the Psycho Tech is not like the old Psycho Tech at all, it's a hybrid of the Psycho Freak and Psycho Tech, but this version is a single Fluid Seam Weld and now, it's also stitchless - that means it would already be warmer, but then the added firewall and 0.5mm of neoprene makes it even warmer!
Then there's "Aqua Alpha" a more environmentally friendly lamination glue, but it's also lighter, a lot lighter - like 600grams per suit lighter! OK, so add 0.5MM of neoprene, add a LOT more firewall, and using a lighter and more environmentally friendly lamination glue, and a size L 4/3+ now weighs 3.5lbs - and yes, I did weigh it myself!
