There are a lot of options for shell jackets out there these days that, frankly, it can be a little overwhelming. And to make it even more complicated, choosing the right jacket is no longer just about features like pockets, vents, helmet-compatible hoods, and powder skirts. The materials matter, too.
You may have heard of the move away from PFAS (short for perfluoroalkyls and polyfluoroalkyls) in the outdoor industry in response to statewide bans and increasing regulations on their use. The long and short of it is that, historically, PFAS have been used as a waterproofing material in textiles. However, an emerging understanding of the negative environmental and health impacts of PFAS, as well as their ability to persist in human and environmental systems for long amounts of time, is leading to an industry-wide shift away from using PFAS. These substances have often been called “forever chemicals,” thanks to their uncanny ability to enter our water supply and never leave. You can learn more about new PFAS regulations and bans in this explainer.
New rules around PFAS use are really rocking the outdoor industry as brands scramble to change their materials in order to meet regulatory deadlines. And the real question is how brands are going to continue to deliver high-quality gear for snowy, wet conditions without using PFAS.
As a high school junior in 2023, Sam Digiambattista started reading about the problem with Gore-Tex which has, historically, used PFAS in the surface coating of its products to repel water. Motivated to do better, Digiambattista started working toward a PFAS-free option that still offered robust performance characteristics. This led to the founding of Indersity.
Indersity relies on a proprietary product called InderShield™ which is a three-layer shell material developed to achieve 40,000 mm waterproofness (compared to a 28,000 mm waterproofness for traditional Gore-Tex® and a range of 10,000-20,000 mm waterproofness for Pertex® Shield products) and 30,000 g/m2 moisture vapor transmission (MVT) breathability. The layered design of the Indersity shell is relatively common across the outdoor industry, with many brands relying on layers to achieve adequate waterproofness and MVT ratings while creating durable products. So, what really sets Indersity’s shell jacket apart is that it was PFAS-free in its inception. This is Indersity’s first season on the market and so I was curious to see how the Indersity shell jacket lived up to the brand's lofty claims of PFAS-free hype.
The Indersity shell jacket is a unisex product offered in sizes XS, S, M, L, and XL. As someone who is 5’4” and 110 lbs, I’m on the smaller side, so I tested the jacket in a size XS. I find that unisex products can be a bit of a gamble in terms of fit, so I was pleasantly surprised to find that I really liked the fit of this piece.
Overall the fit trends toward the bigger end of the spectrum, making it more of a freestyle or resort-oriented fit. However, I found it to also be comfortable for skinning uphill in the backcountry. And the jacket is a hardshell, but it doesn’t feel stiff and allows for good mobility and function while skiing.The sleeves of the jacket are the right length to fit over the cuffs of my gloves and not too tight (which I hate). The bagginess of the jacket is a nice style without being excessively cumbersome and the hem of the jacket falls comfortably below my waist without restricting motion.
Winter has been slow to get underway in the Wasatch, so I’ve been wearing this Indersity jacket for lots of long backcountry tours as I hunt for the best snow in the Wasatch. I’ve been really impressed with how it has performed so far.
The Indersity shell jacket offers big chest pockets, a helmet compatible hood, inside zipper chest pocket, a powder skirt, a large sleeve pocket, and underarm vents. These are pretty standard features for jackets, but their placement and performance can vary widely. Overall, I thought the features of the Indersity jacket were well thought out.
I really liked the jacket’s big chest pockets. I’m not someone who tends to put skins in my pockets but I will say that the pocket layout of this jacket is pretty sweet. The large chest pockets are the perfect size for stashing skins if you’re lapping a run and don’t want to take your pack off. I also found myself putting some snacks in these pockets for easy access on the skintrack. They were placed well so that my backpack chest strap clipped above them, meaning that I could actually put things in them without it interfering with how my pack sat on my body.
The vents are well-placed and large enough to allow for solid temperature regulation, which is especially important for skiers who spend a lot of time in the backcountry transitioning between skinning uphill and skiing down.
In the shift away from PFAS, there are questions around whether PFAS-free jackets will be able to be as high-performing in wet conditions, so obviously I was curious whether the Indersity jacket would feel noticeably different than other hardshell jackets I’ve had.
Shocker, it really didn’t. The jacket repelled water well, blocked wind and helped keep my body heat in. It didn’t perform noticeably better or worse than other hardshell jackets I’ve had and I think that’s a great thing! It means that high quality hardshell jackets are possible without PFAS and without changing our expectations for the performance of products.
Over the years, I’ve been inclined to choose hardshell jackets for skiing (backcountry and resort). I like to feel protected and comfortable in windy, wet conditions. The Indersity shell jacket is a really solid option for all types of skiing and its materials innovation is an added bonus. I’m certainly stoked to have this jacket in my rotation for this season and I appreciate that Indersity is committed to performance while also being conscious of their environmental impact.
