Review: Alpinestars Big Sur Gore-Tex Pro for Tech-Air gear

Reviews and tests 14 March, 2018

We analyze...

The Big Sur Gore-Tex for Tech-Air set by Alpinestars, made up of a jacket and pant, stands out for being very technical, and is designed for the more adventurous and those who travel really long in all kinds of conditions and seek a gear of maximum quality. The main advantage of this touring jacket is that it is prepared for the installation of the brand's Tech-Air Airbag system and, undoubtedly, together with the pant, they make a very complete tandem.

Materials and construction

Both the jacket and the pant are made with multiple fabrics with reinforcements in critical areas to offer high levels of durability and resistance to abrasion.

The jacket has Armacor reinforcements on the back and on the forearms offering excellent resistance to abrasion in key areas of impacts.

To improve the mobility and comfort of the rider, we have elastic accordion inserts on the elbows and on the back.

The pant, on the other hand, also incorporates elastic inserts in the waist, crotch and back of the knees.

In the knees we also find elastic accordion inserts, while a little further down, inside the twin, we see a leather panel to protect us from abrasion.


Inside the jacket and pant is the Gore-Tex Pro laminate membrane. As is known, Gore-Tex is the material that best protects when weather is not good and the fact that it is laminated reduces the weight of the whole and improves the comfort of the rider in his movements.

Inside of the jacket we find the long-sleeve removable thermal lining to improve the insulation when we roll with low temperatures. In the hottest days we can remove it to circulate with total comfort.

The pant also has a removable thermal lining and a mesh fabric on the inside to increase breathability. On the neck of the jacket and on the inside of the waist of the pant we find a soft quilted lining for greater comfort.


The Big Sur Gore-Tex jacket has a very advanced ventilation system. It has air inlets and outlets with zippers in the front and back, providing excellent air flow.

Being a gear designed to make long distances and roads of all kinds, Alpinestars have paid special attention to the security section. Therefore, the jacket incorporates removable protections on elbows and shoulders Bio-Air with CE certification.

In addition, on the shoulders we have GP LITE slides made of molded TPU with fabric covering.
