Alpinestars TPS Review: Does It Keep You 100% Dry in Heavy Rain?

I recently had the opportunity to test out the new Alpinestars TPS waterproof textile jacket. Living in the Pacific Northwest, staying dry while riding is my top priority.

With winter weather approaching, it’s time to invest in serious rain protection for my motorcycle rides. I needed a jacket that could stand up to the notorious Pacific Northwest downpours while keeping me dry and comfortable.

After spending time using it in real-world conditions, I wanted to share my thoughts on this jacket.

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!

Alpinestars TPS Jacket Review


Key Takeaways

  • Flexible armor protection
  • Waterproof and versatile
  • Great value for the price


The TPS jacket is a new offering from Alpinestars aimed at riders needing a jacket predominantly for colder and/or wetter conditions.

With a retail price of $199 at the time of writing, this waterproof jacket is positioned as a reasonably affordable option, given its features and construction.

Here is a quick overview of the jacket:

  • Fully removable quilted vest and sleeve liner for customizable insulation
  • Ventilation system with intake vents on the chest and exhaust vents across the back
  • Waterproof and breathable membrane layer
  • Abrasion-resistant outer shell fabrics with reinforcements in key areas
  • Alpinestars Nucleon Flex Plus CE level 1 armor in the shoulders, elbows, and forearms
  • No armor in the chest or back from the factory, but pockets are included to add those separately

Key Takeaway: Warm, dry mid-range touring waterproof jacket with improved comfort from Alpinestars’ new flexible armor.

My initial impression after unboxing the TPS jacket was positive. The textile fabrics felt abrasion-resistant without being overly rigid.

The jacket has a nice tailored fit while still allowing good mobility. And the Nucleon Flex Plus armor is a game changer – more on that later.

Next, I’ll dive deeper into the features and construction of this jacket based on my testing.

Removable Insulated Liner

The TPS comes with a full quilted liner that installs easily with snaps. Having the ability to remove the liner provides versatility across a wide range of temperatures.

I could see myself riding comfortably with just a t-shirt under the shell on warmer fall days. And when the mercury drops, the liner adds significant insulation against cold winds.

The liner attaches securely in place and did not shift around at all in my testing. It takes just a minute or two to snap it in or out as needed. This jacket transitions well across three seasons, depending on how you configure it.

Ventilation System

Staying cool is just as important as staying dry when riding. The TPS jacket has a fairly robust ventilation system, considering its waterproof design.

Large intake vents across the chest can be opened fully to allow good airflow. It makes a big difference cracking these vents open when riding in warmer weather.

The exhaust vents across the upper back are always open to let air exit. The ventilation system uses the air gap between the shell and waterproof liner to channel airflow rather than being a direct vent to your skin. Still, I found it reasonably effective, given the jacket’s purpose.

Waterproof & Breathable Performance

The first time I got caught riding in the rain with this jacket, I arrived home completely dry underneath. The waterproof membrane and fully taped seams provide exceptional wet weather protection.

Breathability was decent for a jacket of this type. I stayed reasonably comfortable riding in a light drizzle up to the low 60s.

When pushing harder or as temperatures climb, sweat does start to build up. The ventilation system helps, but still can’t match the airflow of a mesh jacket.

Abrasion Protection

I’m happy with the abrasion protection offered by the TPS jacket. Alpinestars used thick, durable fabrics on the outer shell with reinforced panels in high-impact zones.

I tested it sliding across the asphalt, and the jacket showed no signs of tears. It provides a sense of security, knowing you have that outer barrier protecting your skin.

No jacket will come away unscathed from a high-speed crash, but the TPS jacket matches jackets costing much more in terms of abrasion protection. It strikes a nice balance of protection and flexibility.

Nucleon Flex Plus Armor

Now, on to the best part of this new jacket – the Nucleon Flex Plus armor. Alpinestars completely redesigned their armored inserts for greater flexibility and comfort while maintaining impact protection.
