Arcteryx Alpha SL jacket for men is super light, hence SL in the name, and yet completely waterproof and breathable rain jacket suitable for the hardest outdoor activities like rock and ice climbing, mountaineering, and alpinism.
This is a Gore-Tex jacket with 40 denier ripstop fabric and PackLite membrane, and with only 305 g (10.8 oz) average weight. There exist versions for both men and women, with essentially the same features.
What makes Arcteryx Alpha SL jacket so good
The word Alpha denotes the series focused on climbing and alpinism. This implies that it is designed to be compatible with a harness, and the features include:
- the appropriate length,
- the position of the pocket such that it can be used when you have a harness or hip belt on,
- helmet-compatible hood,
- drop hem,
- hemlock inserts which help prevent the jacket from riding up under a harness,
- high durability-to-weight ratio,
- lightweight materials,
- minimalist design,
- extreme packability in the included stuff sack.
In the specifications below you will see N40r, which means 40 denier nylon ripstop. So this is not a hard shell material, and this is the reason I include this jacket in the list of rain jackets for men. More about various types of breathable materials you can read in my another text.
SL series should not be mixed with Arcteryx Alpha FL jackets which are the top class regarding the durability and other features (like Gore-Tex PRO membrane). You can see more in this text. So SL series is a minimalist jacket mostly aimed at emergency use when needed against elements, and not for everyday wear and tear.
This is a 2 layer jacket with PackLite membrane. The jacket has one single chest pocket. I am sure this is justified in view of the purpose and design of this jacket, but this is far from what I love to have in a jacket. One drawcord with a toggle is on the hem. On the cuffs, you have velcro tabs, no elastic.
The hood is very functional, helmet-compatible, fully adjustable, with three adjustment points. One toggle and drawcord is on each side of the face, and one on the back. The brim is simply perfect.
Zippers are waterproof and without external storm flaps.

Conclusion & rating
To conclude this text about Arcteryx Alpha SL jacket for men and women, this is a kit designed for a very specific purpose, and as such it is really great. This is a very reliable tool that will keep you safe from elements. But if you decide to buy it, bear in mind its true purpose and the lack of many features which you might love to have in a jacket which you would use in daily life. Note that this jacket is included in my Arcteryx jackets list, so please have a look.

You might want to check also this new Marmot Magus jacket for men, which is a bit lighter than the Alpha SL jacket and with similar features. Check also this Marmot Spire with a 3-layer Gore-Tex fabric, or the Outdoor Research Optimizer which is a hard shell Gore-Tex.
As already pointed out in the title, there exists Arcteryx Alpha SL jacket for women as well, with the same features.
Thank you for reading, I shall be happy to have some comment from you, there is a comment box below. Have a nice day.
This seems like a pretty cool jacket…except for the fact that it only has on pocket. Would probably be a deal breaker for me lol.
I have been considering going mountain climbing this summer (for the first time) and I have been looking for supplies that I might need. Do you have any suggestions?
Hi Jeff, you are right, I also love to have many pockets. Though this is technical kit and pockets are not essential in principle.
