Sherpa Adventure Gear Sonam Quarter-Zip
INITIAL REPORT - April 30, 2010
TESTER INFORMATION
I have been backpacking for over 30 years, all over California, plus many western states and Minnesota. I hike year-round in all weather, and average 500+ miles (800+ km) per year. I make a point of using lightweight gear, and smaller volume packs. Doubting I can ever be truly UL, I try to be as near to it as I can yet still be comfortable. I start early and hike hard so as to enjoy the afternoons exploring/chilling. I usually take a freestanding tent and enjoy hot meals at night. If not hiking solo I am usually with brother-in-law Dave. The Product
Manufacturer: Sherpa Adventure Gear Product Description
The Sherpa Adventure Gear Sonam Quarter-Zip (hereafter referred to as the Sonam or the shirt) is a men's long sleeved baselayer shirt made for the summer months. The shirt has a 2 in (5 cm) high stand-up collar. It does not like to lie down, even when unzipped. Maybe as I wash it a few times and wear it a bunch this will change. Just under the collar in the back of the shirt is a reflective Sherpa Adventure Gear logo, a Tibetan design. On the chest of the Sonam a small pocket has been welded on. This pocket is accessed by way of a 4 in (10 cm) vertical zipper. The Sherpa name is displayed on the pocket. The size info has been screen-printed on, something I really like to see. Inside the shirt a care tag is found telling me to: Machine wash cold with like colors Use no bleach Tumble dry Low Use a cool iron if pressing is needed Do not dry clean The cut is said to be athletic and it fits pretty close to my body and arms. I look forward to getting it out on the trail. As this concludes my Initial Report, please come back in a couple months to see how the Sonam is working out. Quick & Dirty, Nitty Gritty While I had my doubts about what looked like a mid weight base layer in warm weather hiking I have to say that the Sonam works well when it is warm and better when it is cool. I have taken it on every hiking and camping trip where it has been a welcome addition to my kit. It even repels mosquitoes! Read on for the details. Field Data
The first use of the Sherpa Sonam was on an 18 mi (29 km) section of the PCT near Warner Springs, California (CA). Very cold, with winds to 50 mph (81 km/h). It was 34 F (1 C) when we started. Then we made a day hike of a 24 mi (39 km) section of the PCT south of Tehachapi, CA. Winds blowing at 50 mph (81 km/h) and gusting to 70 mph (113 km/h).blew me off the trail many times. It was 38 F (3 C) at the beginning of the hike. Next was a trip to the Sespe Wilderness for an overnighter to visit the Willet Hot Springs. The temps ran from lows near freezing to 70 F (21 C). Then I took it on an overnighter in Minnesota at Itasca State Park. This trip saw a lot of rain, with temps from 70 to 38 F (21 to 3 C). The picture above was taken in between storms. I used it on an overnighter at a primitive campground called Sawmill and another called Upper Shake, both in the Angeles National Forest. Both trips saw lows to 36 F (2 C). I took it on an overnighter to Fisherman's Camp in Cleveland National Forest. The mosquitoes were bad and the temps were to 85 F (29 C). Next was with the kids for a camping trip to Maplewood State park where we stayed at Lida Lake. Next was an overnighter in the upper Kern River area where the low only made it to 50 F (10 C). Last I went back to the Kern area for three days trying to get down to the Durwood Creek/Kern River cable crossing, and to find and take pictures of waterfalls. Temps ran from a low of 48 to over 90 F (9 to 32 C). I went between 22 and 24 miles. No idea of gain. Here is a picture of it at a camp near a mine shaft near the Rincon trail. Observations
I have really been able to get a lot of use with the Sonam shirt, and I have to say that I really like it. I was concerned going into this test because I knew that I would be in hot weather. I always do carry a long sleeved shirt even in summer, but try for the lightest weight possible. While the company's claim that it would "keep you cool in the heat of the day" is a bit of a stretch the Sonam did not make me overly warm when wearing it as long as I was not in direct sun. In that case the color works against it. The Sonam works well in cool or cold weather too, but only if it is under an outer layer. The material does almost nothing to block wind, so a couple times I needed to put my rain shell over it on early starts in windy conditions. The Sonam is holding up quite well. I wash it after every trip. Sometimes I let it hang dry, which it does very quickly. Other times I will toss it in a medium dryer with other hiking clothes and pull it out after 10 minutes where I will find it almost completely dried already. The zipper is still tracking fine; there are no snags, holes or unraveling seams. It still looks like new. But what will two more months of use do to the Sonam? Well, come back in two months and find out when I post the Long Term Report. Field Data
I have been out a lot since the last report. Here are some of the places I took the Sonam Observations
As can be seen the Sonam has been with me on a lot of trips. As I became unemployed during the Long Term Test phase I had a lot of time to hike and have made the most of it. (And now have a LOT of writing to do. Watch for plenty of reviews right here at this Bat Channel…) While I really like wool for odor control I have to say that the silver ion scheme used in the Sonam works as well as any silver shirts I have owned, and better than most. Even after using it for six days in Yosemite (granted I was not hiking in it during the heat of the day) it had no hiker funk going on. I am looking forward to using it more once the weather cools off and I can wear a long sleeve base layer all day long. It still looks great too. The color is still vibrant, the shape still fine. Well as good as it can be since it has to conform to my shape… ;-) The zippers work (although I still have never used the chest pocket), the seams are sound, the edges are not fraying, the logo is not falling off. It is holding up very well. I look forward to using the Sonam more this winter, and thank Sherpa Adventure Gear and BackpackGearTest.org for letting me test it.
