Stratos v2 Techshell Drystar Review: Does It Keep You Dry?

I recently had the chance to test out the new Alpinestars Stratos V2 Techshell jacket. Over the course of a few weeks and hundreds of miles, I tested it in various weathers, from cold winter rides to warmer sunny days.

In this article, I’ll share my hands-on impressions after riding with the Stratos V2 Techshell and reveal how it performed in key areas like protection, comfort, and breathability.

But, the main question I will answer in this review will be: Is this the best waterproof motorcycle jacket for you? Let’s find out!

What Appealed To Me

Here’s a quick rundown of what initially appealed to me about the Stratos V2:

  • 2-in-1 design – With a removable fleece liner, I could potentially wear it year-round and adapt it for different weather conditions.
  • Understated look – I prefer gear that can transition seamlessly from bike to everyday wear. The Stratos V2 has a low-key technical jacket aesthetic.
  • Waterproof yet breathable – Having a waterproof and breathable Drystar membrane seemed ideal for staying dry without overheating.
  • CE-rated armor – The included shoulder and elbow protectors provide crucial impact protection.

Protection

Protection is one of the most important factors I consider when choosing motorcycle gear. The Alpinestars Stratos V2 comes equipped with CE-rated shoulder and elbow protectors right out of the box. This provides a basic level of impact protection that can be further enhanced with additional armor upgrades.

  • CE-rated Bio Armor shoulder and elbow protectors included
  • Shoulder armor features a softer composite for flexibility
  • Hard shell elbow armor for abrasion resistance
  • Armored compartments for optional Nucleon back protector and chest pads

I was pleased to find that the Stratos V2 includes built-in compartments to accommodate optional Alpinestars Nucleon back and chest protectors.

While these are sold separately, having the ability to upgrade the armor really improves the overall protection this jacket offers.

During testing, the included CE-rated shoulder and elbow pads inspired confidence that I had crucial impact zones covered.

Knowing I could add optional upgrades like back armor down the line definitely provides peace of mind.

Comfort

Comfort is right up there with protection when it comes to importance for me. An uncomfortable jacket can ruin your ride, while a comfortable one lets you focus on enjoying the miles.

The Alpinestars Stratos V2 Techshell has a number of features designed with comfort in mind:

  • 4-way stretch polyester shell for flexibility
  • Pre-curved sleeve construction
  • Fleece liner for added warmth
  • Adjustable wrist and waist straps for a custom fit
  • YKK zippers at cuffs, waist, and front placket

I immediately noticed the flexibility of the 4-way stretch polyester shell. It moved freely with my body through the full range of riding positions. The pre-curved sleeve construction also reduced binding when gripping the handlebars.

The inclusion of the removable fleece liner made this a very versatile jacket comfort-wise. When temperatures dropped, zipping in the liner added noticeable warmth and insulation. For warmer rides, I could remove the fleece liner and just wear the jacket’s polyester shell.

Being able to customize the wrist and waist fit via Velcro straps and adjustable snap buttons ensured I could dial in a secure fit that stayed put at speed. The YKK zippers at the cuffs, waist, and front opened and closed smoothly.

Overall, the mix of 4-way stretch fabric, fleece liner, and adjustable fit points made for a very comfortable next-to-skin feel. The Stratos V2 lived up to its billing as all-day comfort gear.

Breathability

When riding with a jacket that has waterproofing, breathability is always a concern. You want to stay dry without getting that sauna-like condensation underneath.

  • Waterproof and breathable Drystar membrane
  • Rear exhaust vents
  • Perforated collar liner

The Alpinestars Stratos V2 uses a waterproof and breathable Drystar membrane to help prevent liquid water from penetrating while allowing water vapor (sweat) to escape.

I definitely noticed airflow inside the jacket increasing when opening the rear exhaust vents. These side vents on the back of the jacket allowed built-up warmth to exit. Keeping them open helped reduce that sticky moisture build-up during high-exertion riding.

Even with the vents closed, the perforated collar liner and 4-way stretch fabric helped prevent an overly stifling feel.

Breathability seemed decent but not outstanding. In sweltering 95+ degree heat, this is still a jacket you’d want to
