This ST shirt is made for the most severe environments and intense activities. The Polycolon® mesh provides 4 to 6 times the insulating value of solid knits while keeping moisture off the skin. The garment is used extensively by military and expedition forces where intense activity can cause sweat and moisture to put you at risk. The solid knit inlay on the shoulder provides a comfort layer under pack straps. This is also a great choice to be worn under a dry suit. Sizes: XXS – XXXXL.

The polypropylene yarn absorbs virtually no moisture while the mesh design allows perspiration to pass through the garment in vapor form. Nothing wet against the skin!\u003c\/p\u003e\n\u003cp\u003ePolypropylene also has a very high strength to weight ratio providing super light garments designed to withstand years of extreme use. Brynje Super Thermo base layers have been used extensively in expedition work and are worn by Special Forces troops across the globe. Brynje ST garments are not just ideal for high intensity, cold weather activities. Because of the thermostatic qualities of the mesh, these base layer garments are exceptional for warm weather use as well.\u003c\/p\u003e\n\u003cheader class=\"entry-header\"\u003e\n\u003ch3 class=\"entry-title\"\u003eThe Case for Synthetic Mesh Base Layer\u003c\/h3\u003e\n\u003cdiv class=\"entry-meta\"\u003e\u003cspan class=\"posted-on\"\u003ePosted by Brynje on\u003cspan\u003e \u003c\/span\u003e\u003ctime datetime=\"2018-10-21T22:44:49-07:00\" class=\"entry-date published\"\u003eOctober 21, 2018\u003c\/time\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/header\u003e\n\u003cdiv class=\"entry-content\"\u003e\n\u003cp\u003eWhen we started getting inquiries from Canadian and US military for Brynje mesh base layer it certainly made sense. Years ago, the Norwegian government had done studies which showed conclusively that mesh base layer garments performed significantly better than solid knits and thus they have been issuing their troops the Brynje mesh underwear for decades. Guess who trains the US and Canadian forces that travel to the extremes of the planet? Yup, the Norwegians.\u003c\/p\u003e\n\u003cp\u003eRecently Brynje introduced a Merino wool version of their now famous mesh (famous for the first ascent of Everest in 1953). Merino wool has become extremely popular as a material for base layers, including socks. This is because, as a fiber, Merino wool does not itch, it feels warm when wet and it tends not to harbor odors. So, what could be better than Merino wool mesh?\u003c\/p\u003e\n\u003cp\u003eBack in the 1950’s a new miracle yarn was developed that had dramatically improved qualities for wicking moisture away from the body during high exertion and perspiration. It was polypropylene. Companies like Lifa, Helly Hanson and Patagonia started producing underwear made of “polypro” in the seventies and eighties. It worked well but had an unfortunate deficiency, after numerous washings the polypropylene would start to harbored odors. Not a pleasant characteristic. However, the Schoeller company has now developed a new polypropylene yarn called Polycolon® with much improved odor attenuation properties. Additionally, a mesh undergarment allows the moisture to travel through the fabric in vapor form rather than being wicked as a liquid through capillary action. This means that there is much less bacteria being trapped on the fibers and much less material contact with the skin.\u003c\/p\u003e\n\u003cp\u003eThere are three primary considerations for effect base layer clothing: weight, moisture management and warmth. Here are some statistics for different fibers used in these garments\u003c\/p\u003e\n\u003cp\u003eDry Weight:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003ePolypropylene 09 gr\/cm3\u003c\/li\u003e\n\u003cli\u003eNylon                   14 gr\/cm3\u003c\/li\u003e\n\u003cli\u003eWool                   32 gr\/cm3\u003c\/li\u003e\n\u003cli\u003ePolyester 38 gr\/cm3\u003c\/li\u003e\n\u003cli\u003eCotton                   50 gr\/cm3\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eMoisture Absorption as a % of Dry Weight:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003ePolypropylene 5%\u003c\/li\u003e\n\u003cli\u003ePolyester 40%\u003c\/li\u003e\n\u003cli\u003eNylon                   450%\u003c\/li\u003e\n\u003cli\u003eCotton                   800%\u003c\/li\u003e\n\u003cli\u003eWool                   1,600%\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eThermal Insulation Capacity (the lower the number the better the insulation):\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eAir                   0\u003c\/li\u003e\n\u003cli\u003ePolypropylene 0\u003c\/li\u003e\n\u003cli\u003ePolyester 0\u003c\/li\u003e\n\u003cli\u003eWool                   3\u003c\/li\u003e\n\u003cli\u003eCotton                   3\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eIt is clear from the statistics above that polypropylene is a lighter, drier and warmer fiber than nylon, polyester, cotton or wool. However, durability is another important factor. As an environmental issue, the longer a garment lasts the less impact its manufacture has on the environment (and better value to the user). Synthetic fibers can last four to five times longer than 100% Merino wool. This is why Merino wool is often blended with polyester fibers to increase durability.\u003c\/p\u003e\n\u003cp\u003eAnother environmental issue is renewable wool production vs. non-renewable petroleum-based production. While there are wool producers that are excellent stewards of the planet, the fact is sheep produce methane, require substantial quantities of water and can tend to over grazing in high production operations. Additionally, there is the processing of the wool to remove some of the lanolin to allow the yarn to be died. Synthetic yarns, by contrast, while not renewable, use far less petroleum by weight than driving your car. A Brynje short sleeve mesh top weighs only 110 gr. while a gallon of gasoline weighs 6.3 lbs. I think you could make the case that this is an excellent use of petroleum since it is used to fabricate a non-disposable item. The polypropylene fiber also accepts color with very little processing.\u003c\/p\u003e\n\u003cp\u003eSo, if the objectives for selecting your base layer are light weight, warmth and moisture management it’s clear that a mesh base layer garment made from polypropylene simply will outperform all other options. There is very strong science to document this claim. So if you haven’t tried it, you should put it to the test. You’ll be amazed.\u003c\/p\u003e\n\u003ch3\u003eBrynje Size Chart\u003c\/h3\u003e\n\u003cp\u003eUnisex Shirt Sizing Height Waist Chest\u003cbr\u003eXXS 4ft 9″ – 5ft 25″ – 27″ 32″ – 34″\u003cbr\u003eXS 5ft 1″ – 5ft 3″ 27″ – 29″ 34″ – 39″\u003cbr\u003eSM 5ft 4″ – 5ft 6″ 29″ – 31″ 37″ – 40″\u003cbr\u003eMD 5ft 7″ – 5ft 9″ 32″ – 34″ 40″ – 42″\u003cbr\u003eLG 5ft 10″ – 6ft 35″ – 38″ 42″ – 44″\u003cbr\u003eXL 6ft 1″ – 6ft 3″ 39″ – 42″ 45″ – 48″\u003cbr\u003eXXL 6ft 4″ – 6ft 6″ 43″ – 45″ 48″ – 50″\u003cbr\u003e3XL 6ft 7″ – 6ft 9″ 46″ – 50″ 51″ – 53″\u003cbr\u003eWomen’s Shirt Sizing Height Waist Chest\u003cbr\u003eXS 4ft 9″ – 5ft 25″ – 27″ 28″ – 32″\u003cbr\u003eSM 5ft 1″ – 5ft 3″ 27″ – 29″ 33″ – 36″\u003cbr\u003eMD 5ft 4″ – 5ft 6″ 29″ – 31″ 37″ – 39″\u003cbr\u003eLG 5ft 7″ – 5ft 9″ 32″ – 34″ 40″ – 42″\u003cbr\u003eXL 5ft 10″ – 6ft 35″ – 37″ 42″ – 44″\u003cbr\u003eXXL 6ft 1″ – 6ft 3″ 38″ – 40″ 45″ – 48″\u003cbr\u003eUnisex Pants Sizing Height Waist Inseam\u003cbr\u003eXXS 4ft 9″ – 5ft 25″ – 27″ 27″ – 28″\u003cbr\u003eXS 5ft 1″ – 5ft 3″ 27″ – 29″ 29″ – 30″\u003cbr\u003eSM 5ft 4″ – 5ft 6″ 29″ – 31″ 30″ – 31″\u003cbr\u003eMD 5ft 7″ – 5ft 9″ 32″ – 34″ 31″ – 33″\u003cbr\u003eLG 5ft 10″ – 6ft 35″ – 38″ 33″ – 35″\u003cbr\u003eXL 6ft 1″ – 6ft 3″ 39″ – 42″ 35″ – 36″\u003cbr\u003eXXL 6ft 4″ – 6ft 6″ 43″ – 45″ 36″ – 37″\u003cbr\u003e3XL 6ft 7″ – 6ft 9″ 46″ – 50″ 37″ – 38″\u003cbr\u003eWomen’s Pants Sizing Height Waist Inseam\u003cbr\u003eXS 4ft 9″ – 5ft 25″ – 27″ 27″ – 28″\u003cbr\u003eSM 5ft 1″ – 5ft 3″ 27″ – 29″ 29″ – 30″\u003cbr\u003eMD 5ft 4″ – 5ft 6″ 29″ – 31″ 30″ – 31″\u003cbr\u003eLG 5ft 7″ – 5ft 9″ 32″ – 34″ 31″ – 33″\u003cbr\u003eXL 5ft 10″ – 6ft 35″ – 37″ 33″ – 35″\u003cbr\u003eXXL 6ft 1″ – 6ft 3″ 38″ – 40″ 36″ – 37″\u003cbr\u003eHat Sizing Circumference Actual Hat Size\u003cbr\u003eSmall\/Medium 54-56 cm 6 3\/4 – 7 1\/8\u003cbr\u003eLarge\/Extra-Large 56-59 cm 7 1\/4 – 7 5\/8\u003cbr\u003eGlove\/Mitten Sizing Circumference of Palm\u003cbr\u003eSM 6.5″ – 7.5″\u003cbr\u003eMD 8″ – 8.5″\u003cbr\u003eLG 9″ – 10″\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eAll sizes are averages and approximate.
