So easy to wear, so hard to take off
A lot of fleece mid-layers look the part but fall apart under scrutiny: too baggy to layer easily, too hot on the ascent, too cold when the pace drops. The Power Up Houdi is built around Polartec Power Stretch Pro – a fabric Houdini has used and refined for over two decades, and the reason their customers report using it almost daily for more than ten years. Power Stretch Pro uses a triple-fibre construction: a smooth, durable polyamide-reinforced face that resists abrasion and layers cleanly under a shell, with a soft, moisture-wicking polyester fleece interior that moves sweat away from the body during high-output activity. Four-way stretch delivers unrestricted movement in every direction, while the Bluesign-certified production process ensures the chemistry is clean throughout. The versatile cut gives it enough room to layer over a base layer without restricting movement at the shoulders or arms. This is the kind of mid-layer that renders everything else redundant once it's in the wardrobe.

- Air clothes instead of washing if the clothes are not too dirty. You save water, energy and it makes the clothes last longer.
- Feel free to use a laundry bag. It protects your garments and prevents microfibers from leaking out. When cleaning the bag and filter in the machine, make sure to wipe clean and dispose of lint in the bin. Never rinse the laundry bag with water as the fibers can then end up in lakes and oceans.
- Wash at a maximum of 40 degrees.
- Wash with mild environmentally certified detergents and be sure to use the correct dosage.
- Avoid fabric softener. In addition to being bad for the environment, it impairs the garment's performance, especially moisture transport and drying time.
- Do not tumble dry, it wears out both the clothes and the environment unnecessarily. Most synthetic garments dry quickly anyway.
- Hang dry

Since 1993, Houdini has been asking a question the outdoor industry rarely considers: does this product deserve to exist? Founded in Stockholm and shaped by the mountains and waterways of Scandinavia, the brand is resolutely anti-trend. Instead, every design idea is interrogated with a series of asks: will this product last long enough? Is it versatile enough? Does it have a next-life solution?
Often, the answer shows up in the fabric. 100% of the materials Houdini uses for its current collection are recycled, recyclable, renewable, biodegradable, or Bluesign-certified. These are not workarounds – they are the baseline, developed through years of partnerships with the best technical fabric producers in Japan, Italy, Sweden, and beyond. Take Polartec Power Stretch Pro, the legendary fleece that Houdini has used for over a decade. Or Airweb Knit – a seamless, hi-tech insulation fabric from Japan that produces zero waste in manufacture. Or PrimaLoft Gold synthetic fill, which performs like down without using a single bird's feather.
Houdini calls this circular approach “progressive performance design”. It means products are designed to be repaired, reused, or repurposed – so nothing ends up as waste. And it means garments that are genuinely better to use than anything else out there, built to become lifelong companions rather than seasonal purchases. For anyone who takes both their adventure and their responsibility to the planet seriously, this is the brand.
