Protect yourself

The Comp Pressure Suit is Six Six One's entry-level one-piece upper armor, but that doesn't mean it forgoes anything in the area of user protection. In fact it features CE-certified protection.

An articulating ABS plastic back panel enables this certification, and it allows you to move freely on the bike while ensuring vital protection. EVA foam works with the ABS plastic to absorb and distribute impact forces, and it is perforated to let airflow reduce your core's temperature on hotter days. Adding to the Comp's cooling capacity is a lightly compressive mesh chassis.

This chassis securely and comfortably holds the Comp's shoulder and ABS elbow pads in place. Ensuring the pads don't migrate during an impact are hook-and-loop straps at the forearm, and one that connects the chest plate to shoulder pads for fine tuning. At the torso, an ultra-wide, elastic hook-and-loop strap firmly holds the Comp in place without pinching or discomfort.

The Six Six One Comp Pressure Suit comes in Black and in sizes Small through X-large. 

  • ABS Hard Shell panels with mesh chassis
  • Perforated EVA foam
  • Hook-and-loop straps

how much give in the waist section of the 661 comp pressure suit ? do i need a larger size having a bit of a gut ?


The give would be withing the waist size range. For example The XXL is sized at 42"-44" that would be the amount of give it would have. However, I would venture to say that i would give an extra half inch on either side of the sizing chart.

for the snow ...

    Bought for some extra protection on the slopes following shoulder surgery. Fits great [L, I'm 5'11, 185] snug but not restricting. Was worried backplate would feel cumbersome - it doesn't. I cut off the sleeves below the elbow as I don't need/want those pads.

    Not too bulky

      I was afraid I would look like a robot in this thing. It is actually slim enough to fit underneath my tshirt. It has lots of mesh material so it breathes well. At first I thought the fit was too tight, but after a few rides I realized that the tighter, the better. As long as it zips up, you're good. I haven't had to test out the actual protection ability of any of the armor, but that's a good thing .... I certainly feel more comfortable bombing down hills, knowing that if I take a spill I have a little extra protection. I'm not an insane rider, but I don't want to break a wrist or elbow ... This is the perfect piece to cover your upper body. Just get some knee pads and you're good to go!

      Saved me some skin loss

      • Familiarity: I've used it once or twice and have initial impressions

      So I'm new to downhill. I need protection. At my age it's better safe than sorry when trying a new sport.

      This saved my ass from a beating at Keystone recently. I actually got up, laughed brushed the dust off and carried on with my descent after a dive over the front of my bike. Although I'm only a newbie this did what it said on the description, if you're going harder you may need the next model up. The plastic on the shoulder got scratched from my bail but is obviously ready for more. I also noted that the rental store had these in as their standard protection so I'm happy to be using this. Now I just need a bomb proof layer to go over it as what I was wearing got shredded.

      Tools not jewels. Enjoy
