Conquer the storm.

Built for days when you just don’t feel like riding, the Mavic Stratos H2O jacket is waterproof, not water-resistant. The difference between the two is the difference between being caught, miserable, in a light shower or a calculated decision to ride on a rainy day. When you know it’s gong to be wet, reach for the Stratos.

The secret to the Stratos is its Cocona Xcelerator main body fabric. This 20,000mm-rated waterproof fabric is also one of the most breathable in Mavic’s lineup, which means you’ll stay dry from the rain and your own sweat. The Stratos also comes with a detachable hood, fully bonded seams, and ergonomically designed cuffs that easily integrate with gloves. There’s even an asymmetrical front zipper, zippered underarm vents, and a sscuff guard for added durability.

  • Waterproof breathable Cocona Xcelerator fabric
  • Detachable hood
  • Bonded seams
  • Ergonomically designed cuffs
  • Asymmetrical front zipper
  • Zippered underarm vents

Great for mountain biking

  • Familiarity:I've used it several times
  • Fit:True to size
  • Height: 5'10"
    Weight: 180 lbs
    Size Purchased: Medium

I’ve used this jacket a few times and can attest that it is the real deal. What’s best about it though is that it’s bike specific. The cut allows you to be leaned forward in the ‘attack position’ comfortably. The sleeves aren’t too long or short, at least for my build.

The waterproof aspect is why I bought it and I can attest that it does indeed work. I’m a ‘hot’ rider and no gear has ever kept up with me with regard to wicking so I didn’t expect too much from this jacket. But, the vents make up for that in a tolerable way. On one ride I wore it only because it was cold out but kept it on when normally I remove a jacket and tough it out. I got the the top, turned it inside out to dry and kept on trucking.

Possibly the best feature though it the double zip that allows you to unzip the jacket while a mesh vent keeps it zipped for ventilation. Genius.

My one quibble is the ‘velcro’. They come open really easily not inspiring confidence. Although they haven’t come open on the trail so maybe it’s not a real issue?

Killer jacket.

I'm 5'11, 160 pounds. Would I be better off with a small or a medium?

I'm 6'1 and 160. I got the medium and it fits pretty slim. I'm sure the medium would be OK for you.

How is the sizing on this jacket? I'm curious if I should get a L or XL. I'm about 6'3", 200 lbs, fairly athletic, long build. Long arms. Thanks for any advice!

Best Answer

I am your height but with an additional 20 lbs (!). I have the Mavic HC H2O jacket in XL, and it is definitely too big around the chest and waist. I would go with the L, as I found the arms to be very long (i.e. almost too long in XL). Hope that helps.

Thanks! I ended up getting the large and it fits like a "glove" :) The length of the arms is perfect.


...and the kitchen sink!

  • Familiarity:I've put it through the wringer
  • Fit:True to size

You know how some equipment has all those little touches that sound good in theory, but don't really work as they should?

This is not one of those.

The pit zips and XL vent team up to provide great through-flow ventilation. The pack-back fits well over small to medium hydro packs, allowing better mobility and ventilation.

OK, the watch window does fog up a little, especially if the cuffs are closed, and the hood won't actually fit over a bike helmet (though it does zip off), but I am impressed. The off centre front zip sits a little strangely at first. Much better once the fabric softens up.

The sleeves are a great length. Not too long, but certainly provide full coverage, even when moving about off-road. The fabric breathes and sheds water with the best I have tried.

I can't comment on the long term durability just yet. Hey, I was disappointed with my ShowersPass jacket that this replaced, until I realised it has had 7 hard years of commuting, mountain biking and touring (oh, and the odd fast hike)!

One star off for the small issues, which make it not quite perfect, but pretty damn close!

Does this jacket have the "pakback" feature...

Does this jacket have the "pakback" feature which allows you to wear your jacket over your pack?

Best Answer

Hey Spencer,

This jacket does have that pack feature. If you zoom in closely on the detailed picks you can kinda see the zipper toggles to let out the back panel.
