Sleep systems

UK Camp – Winter: System 1

The Minimus jacket is a great all-day warmer, while the down trousers can transform your comfort in and around camp. At night just slip the Filler bag inside the Minimus bag and keep the clothing on when you climb in. You’ve just made yourself a snug base down to -10°C.

Description:

This system combines different components, using both clothing and the Filler bag to boost night time warmth. It also makes use of this diversity to cover several different uses. Warmth on the hill. Comfort around camp. And a good night down to -10°C. But it also gives you the option to pick and mix: for example in milder weather the clothing and the Filler offer two separate ways to boost the Minimus bag to -5°C.

K Series: The Minimus K 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 Filler Down Sleeping Bag

"It is a pleasure, when you know the temperature is dropping, just to slip into another bag and double the warmth factor."
Sam Cook.

Review relates to Minimus Down Jacket

TGO Magazine best buy

"This jacket is remarkable for its warmth, weight and comfort, especially given the add-on option of a hood: I had no choice but to make it Best Buy ... It felt significantly warmer than any other sub-400g jackets and with the optional stud-on, snug-fitting hood ... it'd be awesome. The weight is unbelievable, given that the test jacket features the heaviest, most water-resistant fabric option (Drishell) ... Minimus is amazing."
Judy Armstrong in TGO Magazine.

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."
