Gamma Lw (aka SL) vs Gamma (aka LT) vs Gamma MX: I own all

Best Arc'teryx Jackets: Gamma Lightweight isn't that resistant to rain.

Gamma Lightweight in Phenom color. I'm 5'11" 165 lbs athletic build, size M. As you see it wets out immediately under direct rain for more than 15 mins.

I've got the Winter '24 versions of Gamma's all 3 models.

All three deliver that overall "high quality" outerwear feeling. All are incredibly "fun" to wear. Wind and abrasion resistant too.

But they offer mediocre water resistance.

You need a Gore-Tex shell if you're serious about water resistance.

This translates to Alpha and Beta lines for Arc'teryx.

I've got all Alphas and Betas too, so check out Arc'teryx Alpha vs Beta write up in that case.

Gamma MX is the most water resistant of the three.

Gamma MX in Lampyre, size M. Compared to Gamma Lightweight, it resists rain much better, although no softshell can beat a Gore-Tex hardshell in this regard. MX still soaks after a while.

Gamma Lightweight (aka SL): Fits trimmest. Very light and thin structure. The most comfortable to wear.
Gamma (formerly Gamma LT): Kind of like mesh. Weight and construction wise it's closer to Gamma MX than it is to Gamma Lightweight. Longer sleeves.
Gamma MX (soon to become Heavyweight): Interior is kind of like flannel. Offers most pockets with 2 additional external zippered chest pockets. The longest sleeves.

Here's how Arc'teryx compares the Gamma vs Gamma MX (note that the Gamma Lightweight isn't currently available):

Softshells can be tricky. Andy Kirkpatrick's article on them is a good read.

Their key upside is stretch.

Their light and soft fabric allows for mobility, which increases comfort. They're fun to wear.

This on the side makes them less noisy compared to stiff and crinkly face fabric of hardshells.

Face fabrics

Let's take a look at their face fabrics.

Fortius 2.0 and Wee Burly are alike. Fortius 1.0 is the most different one.

From left to right are Gamma Lightweight (aka SL), Gamma (aka LT) and Gamma MX (soon to become Heavyweight).

Gamma Lightweight's Fortius 1.0: 86% nylon, 14% elastane. 4.7oz/yd2, 160g/m2.
- Four-way stretch-woven nylon/elastane fabric offers air permeable, single layer performance for three-season conditions.
Gamma MX's Fortius 2.0: 49% polyester, 35% nylon, 16% elastane. 7.4oz/yd2, 251g/m2.
- A membrane-free, air permeable 4-way stretch-woven nylon/elastane fabric laminated to low profile, mid-weight 4-way stretch fleece.
Fortius 3.0: 65% polyester, 21% nylon, 14% elastane. 12.2oz/yd2, 414g/m2.
- A membrane-free, air permeable 4-way stretch-woven nylon/elastane fabric laminated to mid-loft, heavy weight 4-way stretch fleece.
Gamma's (aka LT) Wee Burly Double Weave: 56% nylon, 34% polyester, 10% elastane. 8oz/yd2, 275g/m2.
- A four-way-stretch woven fabric that combines the superior strength and durability of a nylon face with the comfort of a microfiber polyester backer.

Yes, Fortius 3.0 is out of context. But I still wanted to share because this information isn't widely available.

Performance data axis of synthetic jackets (table above) and shell jackets (this table) are different. Don't compare them.

From the abrasion resistance and durability point of view, Gamma MX and Gamma (aka LT) are noticeably better than Gamma Lightweight (aka SL). They're thicker and more stiff.

In terms of water resistance though, all are pretty much below average.

Gamma MX still does have the slight edge in this regard because of the higher amount of polyester in its Fortius 2.0, which increases hydrophobic properties of garments.

All are DWR coated.

What is DWR by the way?

DWR is a coating.

It's basically sprayed on to the surface of these jackets as a finish.

It stands for Durable Water Repellent - which means that water will be repelled under wet conditions instead of soaking into the fabric.

DWR also decreases dry time.

It's a good thing these jackets are coated in DWR.

But pay attention to the fact that DWR is a coating - meaning that it will wear off over time.

Which is why you might want to invest in a DWR spray such as this one at arcteryx.com for after treatment.

As you see, there's a strong correlation between FP x FW and temperature ratings, but not more than, say, 80%. I explained why this happens here in this post of mine.
