The DelSur dresses up nicely and does the job outdoors. Shrugged off the gentle steady rain on a bike field trip with kids that had me running beside beginners for 4 miles. Ventilation and warmth are nicely balanced. I would appreciate slightly more shoulder width in this size small that otherwise fits well. It stretches adequately so it’s only the tip of a star short of perfection.

This jacket is great, especially at the sale price! I wore it on the AT on Easter Monday for 9.2 miles at 38 degrees and I was fine with just a long underwear top! Then I wore it in a snow squall on Tuesday in NE PA and it shed the snow very well....It's warm and vented in all the right places...I recommend all the Sierra Madre products that I've purchased or been give as a birthday or Christmas gift...

I LOVE This Jacket ( LTJ) our weather here in East Tennessee is crazy right now ! This jacket is so versatile with lows in the upper 30's and highs in the upper 60s with sprinkles and snow this weekend and don't get me started about the winds... It is the perfect jacket! Even for a city girl

My backpacking buddy now calls me the official "Sierra Madre Advocate" as I sported my new DelSur on a bushwacking hike in the north Georgia mountains en route to the Chatooga River. It is the perfect combination of core insulation and breathability. As the temperature dropped into the 20's that night, I climbed into my SM NINOX flat lay hammock, complete with SM NINOX fly and SM underquilt while still sporting my DelSur. The breathability of the DelSur made for a comfortable nights sleep - perhaps added by the fact that it was too cold for coyotes and bear!
