Patagonia Sun Stretch shirt review

DSC01351As I mentioned last week, there are some, stifling hot, occasions when even the lightest knit baselayers aren’t up to the task.  The latest light (100 grams/meter or less) poly baselayers dry fast, but there’s something about the wicking process upon which modern poly shirts depend that just doesn’t get the job done in serious heat.  Too much moisture is left against the skin, while at the same time the fabric minimizes any benefit you might get from evaporative cooling.  I’ve used poly/cotton dress shirts for quite some time, with a fair degree of success, but after a few days they get nasty and chafe.  More seriously, they are one trick critters.  In anything other than darn hot weather they’ll be in your pack, which during an extended summer rain interlude can mead you’re hauling around a damp ball of slime until the solar gets cranking again.

Patagonia’s Sun Stretch shirt is a, and perhaps for the moment the, solution to this problem.  Made from a 52%/48% nylon/poly woven, the Sun Stretch takes the traditional trekking/fishing/safari shirt and builds it from truly light fabric, namely 76 grams/meter.  This light a fabric just can’t absorb much water, which has been a big knock against 100% nylon wovens. The poly percentage also helps with breathability and a pleasant and fairly non-synthetic against the skin feel, the other reason why until now woven shirts have never graced my baselayer closet.  Because it’s a woven and not a knit, the fabric doesn’t actively seek to suck moisture off your skin, which paradoxically helps in very hot weather by letting evaporative cooling do its thing. The Sun Stretch is not the ideal tool for cold weather, but when moisture transport and overall mitigation is a major concern, it isn’t too much of a liability, either.

Limitations are few. First, it comes in Patagonia’s “relaxed” fit, which means that to get good sleeve length you’ll need to put up with a overly voluminous torso. I’m fortunate in that I can fit into a small, with only the littlest hint of shoulder tightness, and could thus find one on sale. I can tolerate the slightly short sleeves. My vote would be for more conventional sizing. The second limitation is that the stink factor, while far from terrible, is not what we’ve come to expect in the age of Polygiene. With blazing fast dry times it’d still be a good travel shirt, but it would need frequent sink washings to maintain a good margin of social acceptability, especially in the first world.

Detailing and construction quality is typical Patagonia, which is to say quite good. The chest pockets are capacious, the zippers both smooth running and small enough in coil to be unobtrusive. The buttons are sewn on, but plenty thick and feel well attached. Little details, like shoulder articulation and buttons to hold up the sleeves, are all present.  I wouldn’t mind a stiffer collar that would stand up for sun protection, but that’s a small issue.

Fit and nitpicks aside I could happily have this and the Sitka Core hoody as my only next to skin layers, year round.  The Sun Stretch is particularly nice in that it can work backpacking or mountain biking, and transfer to a rural burger joint without too thoroughly screaming; I’m a “technical” yuppie goon.  Taken together the Sun Stretch and Core hoody over 200 dollars worth of shirt, but if you’re going for quality and longevity over quantity, they’d be my suggestion.

  1. Yeah it’s a nice shirt. I’m taking one – along with 1 short sleeve poly – on a thru hike of the rockies this summer. I like how it feels classy too.

  2. I’m going to give the MH air tech stripe shirt a try next week for similar application. In hand it felt like it’d be a decent bit more breathable than the paty and is even lighter.

    Where I have a feeling the sun stretch might have the edge is next to skin feel after 10 hours of hiking, which can be pretty bad with this particular shirt genre.

  3. I was surprised to find that Patagonia does not make a casual, hot weather shirt that also has polygiene treatment. It seems like a no-brainer for the non-dirtbag thru hiking set, which there seem to be a lot of these days. And with significant crossover into the hostels-and-trains obackpacking demographic. For sun protection, stink resistance and burger joint appeal, I’ve been looking at the Columbia Silver Ridge Lite. Unfortunately they don’t publish much detail on their fabric, but it does look interesting: http://www.columbia.com/mens-silver-ridge-lite-plaid-long-sleeve-shirt-1711581.html

    1. I have an ex-officio shirt with the built in Permethrin treatment that I got from Sierra Trading Post for a deal…it worked really well last summer in the Upper Peninsula of Michigan…black flies would land, but not stay on me.

      However, Philip Werner (Section Hiker) has an article on soaking your clothes in Permethrin…I’d get the shirt you want and then just soak it yourself.
