AGE: 71
WAIST: 34 in (86 cm)

HOME: Bay Area, California USA

     I enjoy California's central Sierras, camping every month with a goal to match my age in nights out each year. For comfort I lug tent, mattress, chair and such. Typical summer trips run 5-8 days; 40 lb (18 kg), about half food and water related; about 5 miles (8 km) per hiking day in the bright and sunny granite in and around Yosemite. I winter base camp most often at 6,000 to 7,000 ft (1,800 to 2,000 m); 2 to 3 nights; 50 lb (23 kg); a mile or so (1.6 km) on snowshoes.bisonboxers

My Description:
    Gossamer, stretchy and airy seem the most apt description for these boxers. The material features a network of pin holes about 3/32 in (3 mm) apart throughout the entire garment except for the waistband. The waistband feels like the most substantial part of the garment and also provides real estate for repetitious emblazonment of the company logo. The waistband is black outside with red logo lettering; and red inside with black lettering. The rest of the garment is all one color.
    The boxers are put together with flat seams.
    A piddle port of 4 in (10 cm) has an inside overlap of about 4 1/4 in (11 cm).
    Care instructions and maker information are printed on the back center, just below the waistband, occupying about 1 3/4 x 1 1/4 in (4.5 x 3 cm).
    Wow, these feel light and airy! It could be easy to forget they are on. About the only thing I feel is the waistband. The size fits me perfectly--with the amount of stretch built into the boxers. No tags suits me perfectly as well. The material is so thin I am particularly interested in discovering how well the fabric wicks off moisture without getting 'full'. I'm also rather nitpicky about pilling, so that will be a subject of testing as well.

    Stitching looks perfect--no loose threads or missed stitches. The garment appears to be very well constructed.

    Evidently the garment requires no special care in laundering, which is good because it won't get any. I wash when the hamper's full; it all goes in the washer together and then the dryer. If I think of it I do remove lighter synthetics before they fry among the towels.
Field Conditions:
    1. May 10-14, 2019: Kibbie Creek, Stanislaus National Forest, California. 4 nights backpacking, 15 mi (24 km); leave weight 45 lb (20 kg); 3 camps; 40-70 F (4-21 C), sunny, no wind; 5,100-6,400 ft (1,550-1,950 m). 48 hours wearing; 4 mi (6 km) hiking.
2. May 29-Jun 2, 2019: Kibbie Ridge, Stanislaus National Forest, California. 4 nights, 2 mi (3 k) hiking and 11 mi (18 km) backpacking; leave weight 40 lb (18 kg); 3 camps; 45-75 F (7-24 C), half sunny, half cloudy with a few spits of rain and two heavy showers; 5,100-6,700 ft (1,550-2,000 m). 62 hours wearing.
3. Jun 21-22, 2019. Lake Shasta, California. 2 days driving/1 night car camping. 92-55 F (33-13 C), sunny, 1,100 ft (325 m)
    4. Various walkabouts.

    1,2. Kibbie: I left the car hot and heavy and arrived at first campsite tired and sweaty just as the sun was sinking beneath the trees. I thought the boxers might dry enough as I pitched the tent and managed other camp chores, but I started getting cold. They were under a pair of synthetic hiking shorts which also were not drying out in the waist band, so I'm not allocating all of the result to the boxers. However, much as I enjoyed wearing the boxers for the 10 hours before the hike, I felt a little pinched in them on the traipse in. Could be I was just grumpy, or could be that's why I was. At any rate, I dispensed with hiking in the boxers for the balance of the trip.

    However, I did log a total of 48 hours of wearing the boxers during the trip (in addition to 10 hours a couple days before starting the trip). I slept in them three nights and wore them during much of the non-hiking day hours. Occasion to rinse them did not present itself. They were comfortable enough I barely knew I had them on. They did not stink. My hiking shorts have suspension built in, which proved I should have been more careful in clothing selection at home. My camp pants don't. For the hours of wearing the camp pants and not the shorts, the Bison Boxers kept things remarkably comfortable in the cool of evening as well as the heat of day.

    On shaving day I tested the boxers as a solo garment. It could be easy to get used to that level of comfort. I don't know how many hours involved this aspect of the test or whether I did much if any scampering about in brush, but the boxers were briefly, at least, exposed to the elements and show no signs of pilling.

    3. Shasta: I logged about 36 hours in the boxers on this very hot trip. As uncomfortable as I was in the heat, the boxers helped to make things better by being incredibly light and breathable. They wick moisture well and stay dry.

    4. Having concluded that I don't particularly find the boxers well-suited to backpacking, I've been logging hours in the urban jungle. I find them supremely comfortable for such endeavor.

Field Conditions:
Accumulation of 121 hours wearing for driving, urban walks and around the house.

    I find the boxers supremely comfortable for everyday wear. They don't bind or chafe or ride up or down. They've not felt sticky or sloppy even when sweated up a bit. They are almost not noticeable, except for keeping things in place. I lost track of how many times I've washed them. They show no signs of wear or weakening; and they've accumulated no odor.

While I can maintain a graceful demeanor while putting the boxers on, they seem to find a way to cling to my feet when I try to step out of them. I'm not used to that, and I've yet to bring myself to remember, which leads to a lot of stumbling around. I don't know if I've stressed me or the boxers most, but so far nothing has permanently stretched out of place.

Total wearing: 292 hours

SUMMATION:  Light, airy and stretchy.

Thank you Mountain Khakis and for the opportunity to test this product. The test is complete.
