This bra is really perfect…

This bra is really perfect, first time after my race I'm not frozen when I get home, no humidity, I love it

Good, but...

I like it, it's very comfortable, but taking it off, especially after sweating, is not easy, and after all, it is a sports bra. For this reason, I unfortunately use it quite rarely. A very big plus for the composition.


bought in size S, it suits me, indeed the adjustment possibility could be wider to further tighten the height in the back. otherwise very pleasantly surprised, I just invested in merino wool t-shirts for my husband and I and I found it logical to have the bra in the same material. tested on a snowshoe hike today, it was very pleasant, we sweated but no smell... it's great. so some no longer want pink colors, personally I love pink and am disappointed not to have found the plum model which will go perfectly with the t-shirts purchased (in the same color)... rather than removing a color... perhaps we should instead think about adding some 😉. And if you ever have the plum left in stock somewhere, I'm interested!!! 🤩

Merino wool sports bra TREK 500

I bought this sports bra to avoid sweat odor, and it works really well! A must-have for multi-day hiking!

Say goodbye to stuffy heat and unpleasant smells, it’s worth buying!

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!

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.

Additional Product Information


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.
