The draw: Warmth

Specifically made for swimming in cold water (Blueseventy says down to 48 degrees), the inner liner is made of a mid-weight material for increased warmth. More tailored to athletes with a slim build, pulling this suit on we found some initial tightness in the shoulders and elbows, but after a few sessions that loosens up. Balance was even, and we found our legs were able to relax or kick hard without fighting the neoprene. The elbows felt free and loose during the catch, but tightened up on the recovery. The thermal socks were a bit hard to get used to, and the drag was noticeable. As expected, this suit was the warmest one we tested, keeping us toasty in water temps down to the low 50s.
