Brand profile
German maker of avalanche safety gear and merino wool mountain apparel, founded in 1980 around the first dual-frequency avalanche transceiver.
4 brands like Ortovox like Mammut, Black Diamond, Icebreaker →

Ortovox develops avalanche safety equipment and wool-based mountain apparel from its base south of Munich. Gerald Kampel and Jürgen Wegner founded it in 1980 around the first avalanche transceiver able to transmit and receive on both radio frequencies then in use, a design that became an industry standard. Wool apparel followed in 1988 and now anchors the range, using Tasmanian merino and Swiss wool in base layers, fleeces, insulation and shells alongside technical fabrics. Transceivers, probes, shovels, airbag systems, ski-touring packs and avalanche training round out the business.
Overall fit
slightly small
Ortovox generally fits on the slim, athletic side of European mountain sizing, so many shoppers find it a half to full size snugger than comparable American outdoor labels.
Tip: If you are between sizes or want room for layering, size up one — especially US shoppers used to roomier outdoor brands.

By category
| Category | Runs | Shape | Size advice |
|---|---|---|---|
| Hoodies & sweatshirts | slightly small | trim, slightly tapered fleece/merino hoodie meant as a mid-layer | Take your normal size for layering under a shell, or size up if you want it to sit loosely over other pieces. |
| Jackets | slightly small | trim technical shell and insulation fit with pre-shaped arms | Size up if you plan to wear thick mid-layers underneath or prefer a looser shell. |
| Shirts & overshirts | slightly small | slim to regular alpine shirt cut, closer through the waist | Consider one size up if you have a broader chest or want a relaxed drape. |
| T-shirts & graphic tees | runs small | close-fitting merino tee/base layer that follows the torso | Size up if you prefer a relaxed everyday tee rather than a next-to-skin base layer. |
| Trousers & pants | true to size | articulated, slightly tapered touring and mountaineering cut | Stick with your usual waist size; check inseam as legs tend to run long. |
