Sleep systems

Toubkal Winter: System 1

The Alpine Ultra jacket has been called ‘the perfect Alpine downie’, ultralight and good for -10°C (14°F) on the mountain, while the down trousers can transform your comfort in camp or hut. Wear this down gear at night inside the Minimus bag and you'll boost the bag’s performance from +5°C (41°F) to -6°C.

Description:

The Minimus bag gives great warmth-to weight performance at 465g, a very small pack item to form the basis of this sleep system and warm enough for the heated huts with a +5°C rating. But wear the down clothing inside the bag at night and you'll boost its performance from +5°C to -6°C. If you expect your nights to be colder than this, look at System 2.

In the daytime the Alpine Ultra is a superb down jacket, ultralight to wear or carry, while the down trousers are likely to be welcome on chilly evenings.

K Series: The Minimus K Down Sleeping Bag is available in the K Series: performance is the same, but the exceptional loft of 1000 down reduces the weight of the bag to an amazing 380g (13.4oz).

Review relates to Minimus Down Sleeping Bag

"Over the past twenty five years have tried and tested many bags but as yet I can honestly say, have not found a more comfortable bag."
Jeremy Hastings, Islay Bushcraft.

Review relates to Alpine Ultra Down Jacket

"It's the perfect alpine downie - 330g and rated to -10 degrees - it blows the competition out of the water. Whilst the weight is awesome, you also get a tiny packed size out of it meaning that your down jacket won't eat up half your backpack space so you can go with a small backpack (20L) and keep a light and fast rhythm to your climbing."
Jon Griffith.

Review relates to Minimus Down Trousers

Backpacking Light - Highly recommended

"Overall Rating: Highly Recommended. These down pants are simple and light, just the way we want them. They have the most loft and highest loft:weight ratio of the three pants we tested; I couldn't ask for more. I found that I could extend the warmth of a 30°F (-1°C) sleeping bag to 15 °F (-9°C) by wearing these pants and a lightweight down jacket inside."
Will Rietveld, Backpacking Light. Read full review.

Review relates to Minimus Down Socks

"The Minimus trousers and socks are amazing. The combination of weight, compressed volume and insulation properties is outstanding. With down I was able to reduce my pack weight significantly."
