The Union is the undisputed favorite around the Radar Headquarters due to its easy to ride ability without sacrificing any performance. Extra width allows you to ride the ski at slower speeds and improve at a rapid pace. This ski performs amazingly well between 24-32 MPH and will have you making endless turns on the lake all day long.

Find my slalom ski size

A slalom ski is sized on two things: your weight, and the speed you ski at. Faster boat speeds support a shorter ski; slower speeds need more surface area, so you size up.

Rider weight 30–32 mph 32–34 mph 34–36 mph
Under 45 kg (100 lb)63"63"61"
45 – 61 kg (100 – 135 lb)65"63"63"
59 – 73 kg (130 – 160 lb)66"65"65"
68 – 82 kg (150 – 180 lb)67"66"65"
77 – 91 kg (170 – 200 lb)68"67"66"

Most recreational skiers on Kawartha lakes run 30–32 mph, so read the first column unless you course ski. Between two sizes? Take the longer ski — it is more forgiving and easier to get out of the water.

Still not sure? Call the shop on 705-652-6852 — we will size you in two minutes — or try it in person at our Lakefield store.
