Why We Like The 3900 Ultra Protective Heavyweight Vest

While we're big fans of riding like we're invincible, the mountain has a knack for throwing up a root where we least expect it to keep us reminded of who is boss. Getting tossed into the woods can be a day ender — or worse — a season ender, but with a little extra support from the Troy Lee Designs 3900 Ultra Protective Vest you've got a better chance of getting up and walking away from your crash. This vest is lightweight and breathable, strategically paneling dense bio-foam protection down your spine, chest, and other key areas to keep you safer while you conquer the mountain. It slides on with a wide neck opening to maximize comfort, and sits snug against your skin to layer comfortably underneath your jersey on days when you're going to get a little rowdy on the trail — but who are we kidding, that's every day.


  • A lightweight vest to keep you protected
  • Dense bio-foam panels the spine and key areas

Instant comfort and Effectiveness!

I skied for a living when I was young. I had some huge health issues that involved multiple open heart surgeries. The wrong fall and any impact on my torso results in pain and problems... The second run with this protection on Proved The product works perfectly as crashed on Very Hard snow right on my chest.... No pain, just up and away I went! and It's very comfortable, Zero movement restriction and wearing it doesn't make me look like the Stay puffed marshmallow man
