Fourth Element J2 Baselayer Men's Leggings is crafted from 90% recycled polyester and 10% elastane, the new OceanPositive J2 redefines what it means to be eco-friendly in the world of activewear.
This simple, close fitting garment, with super flat seams and soft waistband creates a dry zone next to the skin, offering better thermal protection for extended use under a drysuit. The classic Fourth Element J2 Leggings now comes in black. Pair it with the Fourth Element J2 Baselayer Long Sleeve Top or Fourth Element J2 Baselayer Short Sleeve Top.
The fabric boasts excellent anti-microbial properties, powered by advanced silver ion technology, keeping you fresh and comfortable during and after dives. Additionally, the unique fabric design offers outstanding wicking capabilities, rapidly moving moisture to the outer surface to keep you dry and comfortable.
Divers, in particular, benefit significantly from the J2 when used in combination with a mid-layer, like the Fourth Element Arctic Undersuits. The J2 adds a huge amount of additional warmth and comfort because a bulkier mid-layer won’t always stay in close contact with the skin as the diver moves.
When you examine the inside of the J2 closely, you'll notice a waffle-like texture. This design creates numerous air spaces and contact points for moisture to wick up to the outside of the garment, enhancing its efficiency in keeping you dry.
FEATURES:
- Developed for J2 caving expedition
- Tested for 19 days, 24 hours a day
- Anti-microbial silver ion technology
- Lightweight and compact
- Fast wicking extreme performance
- Perfect for extended drysuit diving
