Discover how the M's Alto Houdi uses natural materials to regulate temperature during active use, making it a top choice for hiking and everyday wear.
Quick answer
The M's Alto Houdi is a merino-wool blend hoodie designed to keep you comfortable during active use by naturally regulating heat and moisture.
Why temperature regulation matters for active use
When you're hiking or moving, a fleece that traps too much heat can leave you sweaty and cold. The M's Alto Houdi addresses this with a focus on breathability and moisture management, not just warmth.
The trade-off: natural fibers need care
Woolly Treemerino™ is a Swedish-made material that regulates temperature well, but it requires more careful washing than synthetic fleeces. If you prefer low-maintenance gear, a synthetic hoodie might be easier.
Diagnosis: Is the M's Alto Houdi right for you?
- Symptom: You overheat quickly in standard fleece hoodies, even when not pushing hard.
- Likely cause: Synthetic fleeces trap heat and moisture, especially during active use like hiking or running errands.
- Corrective action: Switch to the M's Alto Houdi, which uses Woolly Treemerino™ merino wool to wick moisture and regulate body temperature naturally. Check the fit: the precise cut is designed for layering, so size up if you want a looser feel.
- Stop or choose another option: If you prefer machine-washable, low-maintenance gear, consider a synthetic fleece instead. The Alto Houdi requires gentle care to preserve the natural fibers.
Product facts
