Product Customer Reviews

I bought this sports bra to avoid sweat odor, and it works really well! A must-have for multi-day hiking!
This is my first time buying a wool sports bra. Although the unit price is slightly higher, I really appreciate its comfort and breathability! Especially after intense exercise, even if you are sweating, your underwear will not smell like sweat. It is really amazing! Worth recommending and must repurchase!
My wife said it would be comfortable to wear
Good to wear and repurchase
Hyper.comfort I also use it for sport
Very comfortable and practical for hiking
Very satisfied
A very comfortable, soft bra that does not retain perspiration odors. I highly recommend !
Used during a one-week roaming stay in Morocco, comfortable to wear and quick cleaning/drying.
Good support
The bra fits very well, it is pleasant. Great merino material. I can't fully assess the lifespan yet, I've been using it for half a year. I definitely recommend it.
Super nice
Pleasant for hiking, dries quickly. But I had to take a size larger than recommended by the calculator on the website. The setting options are limited - it won't suit everyone.
RAS
Also great to carry with a backpack.

Additional Product Information
Composition
Main fabric: 51.0% Wool, 5.0% Elastane, 34.0% Viscose, 10.0% Polyamide ; Yoke: 66.0% Wool, 24.0% Polyamide, 10.0% Elastane ; Elastic band: 84.0% Polyamide, 16.0% Elastane
How is the bra’s support guaranteed? (level 3 on a scale from 1 to 5)
This sports bra has been rated a 3 for its level of support on a scale from 1 to 5. It is suitable for all moderate impact sports.The Merino wool Trek 500 bra reduces chest movement by 29.8%. All our products are validated in our laboratories by our chest support test (measures the reduction in chest movement). They are evaluated and classified from 1 (low support) to 5 (strong support).
How to choose your bra size
This Merino wool bra is available in the following sizes: 2XS, XS, S, M, and L.It measures on the smaller side, so if you are deciding between 2 sizes, we recommend you go for the next size up. For support with your size choice, click on “Size guide” (top right of the page).
What type of support does your merino wool bra offer?
We wear our hiking bra and our sports bra several hours a day. Therefore, it’s important that this model offers overall coverage support rather than compression support. This gives good chest protection while offering freedom of movement.During the design, we placed importance on the good level of chest support, without necessarily putting the neck muscles (trapezoids) under tension.
A small responsible action?
We succeeded in using an innovative process in the design of the removable pads that outline the chest. The pads are designed half with scraps from the bra manufacture, and half from polyester fiber.
How to wash your merino wool bra
We recommend that you machine wash your Merino wool Trek 500 bra at 86°F on a normal cycle, preferably with liquid detergent.Dry flat. NEVER tumble dry.For more information: Visit our website
Tip before use
For a softer feel and for hygiene, wash your bra before first use.
Product testing
The Merino wool Trek 500 has been validated in the field in July 2020 by a group of 6 testers in the Alps. Its support level and its “No Odor” properties were particularly appreciated.
