Description

Brynje original Super Thermo (ST) mesh is made from 100% Schoeller® Polycolon® synthetic yarn, knitted into a 3/8″ open weave mesh that provides 4 to 6 times the insulating power of any solid knit by weight. 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!

Polypropylene 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. “Making the case for synthetic mesh base layers.”

    (Partly copied from my review of the wool version) Works very well. I’m a heavy sweater, regardless of layer arrangement. The mesh shirts allow me to stay warm longer when I stop moving, and my layers seem to dry out more quickly on my body. Seems durable and so far hasn’t hasn’t held onto odors. I do wish there were something other than the mesh to grab to pull the sleeves all the way onto my arms. They seem to want to bunch at the wrist. Maybe a little more room in the forearms would be helpful.

    Bought this top and wore it through 30 days of USMC training with temperatures regularly reaching double-digit negatives. Perfect base layer to wear stand-alone under a shell or under additional mid-layers if things got super cold. Kept me warm the entire time and was easy to clean. Highest recommendation for military or non-military use. 100% worth the money and a piece of gear I’ll use for hunting, skiing, and any other cold-weather activities in the future.

    I bought this for my dad. He uses it every morning when he walks the dog. They live in the desert, so mornings start off very cold but rapidly warm up. The base layer is perfect since it keeps him warm when it’s cold and breathes as the temperature rises. He loves it!

    Incredible! Used it for six weeks of the Marine Corps’ toughest cold weather mountain training in the high Sierras and could not be more pleased with its performance. Kept me consistently warm and dry as I transitioned from sweating it out on long movements under heavy load before settling into camp for nights where the temps dropped below zero—wicking abilities are truly incredible. Didn’t take off for a week at a time and it kept working with minimal smell. Customer service also unparalleled.

    I am a ski instructor in Colorado and this layer is by far the warmest and most comfortable one I have. To be most effective I find I need a solid layer directly on top of this mesh layer and when layered this way I am warm on even the coldest days.

    I recently returned from a seven day 1,180 mile journey around Ring Road in Iceland. The weather varied from a misty drizzly day of 45 F and a 13 Mph wind at Grimsey Island Artic Circle to a pleasant 70 F in Egilssadir. Yet, even at 70 F, there was still an occasional cool wind. While hiking to the Arctic Circle, I wore the Super Thermo mesh short sleeve shirt under the Buffalo Special 6 jacket. That was actually too warm. But, with a temperature of 55 F at Glacier Lagoon and a slight breeze, while walking about some trails, I wore the Long Sleeve Super Thermo shirt under a Buffalo wind shirt. I also wore the thermal under the foul weather gear provided for the Zodiac glacier boat tour. I was comfortable near the cooler climate of the glacier.
    While in Iceland, 90 percent of the time I wore only a thermal shirt and the wind shirt for comfort. In addition, throughout my trip, I also wore the Super Thermo Lined beanie. I was very happy with the comfort of these light easily packable products provided me during my exploration of Iceland.

    This shirt absolutely exceeded my expectations! What a fantastic piece of gear! It is very soft and comfortable against your skin and very warm. I wore it for about 7 nights as a sleep shirt as I sleep very cold and it kept me very warm. Wore it around camp as well and it was equally impressive! I’m probably going to buy one in navy with the inlay for wearing with a pack. Excellent product, you won’t be disappointed.

    I agree with Joseph. The neck logo doesn’t serve the shirt well. Other than that, great shirt.

  13. Rick (verified owner)

    Forgot! Great customer service from Jeff. Went way out of his way to get my back order to me. Much appreciated!

  14. Rick (verified owner)

    These work great! Much more comfortable on my winter bike rides. Quality construction and true to size.

    Great except for logo on neck

    I’m 5’3’ and 160 lbs female. I ordered a medium and it fit perfectly.
    I slept in these at 28* with a 10* down quilt and was snug as a bug.
    At 4.6oz for a medium I would highly recommend these for those wanting to cut oz and still be warm!

All sizes are averages and approximate. Your size may vary depending based on your body shape and the model.

Mesh base layers are generally quite stretchy in all directions and are cut long. As the girth increases the length will decrease

Generally the Women’s sizes will be one size smaller than Unisex. I.E. a Unisex SM is equivalent to a Women’s MD.

Laundry Instructions

Merino wool can be worn multiple time between washings which will prolong the garment life and protect the environment. The synthetic fibers like Schoeller® Polycolon can be machine washed and hung to dry.

Hand wash or machine wash on gentle cycle with cool water (not to exceed 85°F).

Line dry. Do not tumble dry.

Do not use bleach.

Do not use fabric softener.

Do not dry clean.
