So cozy and now my every day wear!
I have never tried wool undergarments before. Trying to do some minimalist backpacking and heard good things about this brand. I was not disappointed! I have 2 busty bras on the way!
I no longer wear any other panties except Branwyn. They are the most comfortable and the crotch gusset is the right width for my body. I also use these as swim bottoms, which us especially great for a quick dip in a lake after hiking. My oldest pairs are 2.5 years old and still look great even after nearly weekly use.
I recently read an article that rated athletic underwear for outdoor sports & BRANWYN was rated as one of the best brands. Living an active lifestyle in the mountains of Boulder Colorado, I had to give BRANWYN a try. OMG!!!! I can't recommend this company more highly! They are environmentally friendly and make high quality merino wool underwear/bras that are not itchy in the slightest (not even on my super sensitive skin!). And you know when trying to buy undergarments for the first time from a company online, it's often a guessing game to know if you will like the product or know what size to purchase. But BRANWYN understands this and offers AMAZING policies like first time satisfaction guaranteed or "instant exchange" which allows the customer to try more than 1 size at the same time (especially helpful to me as I'm often in between 2 sizes). If that isn't enough, they have the BEST customer assistance I've ever encountered; so informative about their products, easy to reach, kind, and they truly want you to love their stuff (customer service person Pearl is a rock star - thanks Pearl!). Lastly, if you want to know what I've tried, it's the Essential Bikini which comes fun colors, flatters my back side, fits even better after washing, and dries fast on a clothes line. Can't wait to try more products. Thanks BRANWYN for keepin' it user-friendly!!
First off: I live in Florida. For those of you who think I’m nuts for wearing wool bras and undies, I have news for you. THEY ROCK! The anti microbial properties of wool keeps me fresh and odor free even after a summer day in the humidity and heat. I have 2 bralettes, 1 busty, 1 racerback, 2 swag sweatshirts and 2 undies. I just purchased the undies - I’ll be buying more!
