*ALL WHS SALES FINAL MODEL: 0.5 mm MAKE: GEOPRENE RANGE: 21 - 24C / 69 - 74+F We call it the Geo Shorts because it's Matuse's first pair of shorts -- and they're obviously made from Geoprene (and HydraSilk). Straight forward. Easy to remember. Ichiban infused. — How to Connect Your Geo-Shorts to the Neptune Pro Using the LTS System: Step 1: Remove the Laces Start by removing the waist laces from your Neptune Pro Boardshort. Step 2: Reverse the Geo-Shorts Flip your Matuse Geo-Shorts inside out. (Yes, they’re reversible — intentionally.) This puts the integrated lace system in position to connect. Step 3: Thread and Connect Slide your Geo-Short inside the Neptune Pro. Thread the laces through the LTS eyelets—right lace through the right eyelet, left lace through the left. Then feed them back through the rubberized eyelets on the Neptune trunks to lock everything in place. Cinch to secure. And that’s it — you’re dialed. What you get: a unified short + liner system engineered for ultimate comfort with added warmth, anti-chafing for longer sessions, and total mobility — in or out of the water. One short. Two layers. Zero distractions. This is the future of boardshort design. Only from Matuse. What is Geoprene Technology? Learn More
