Sleeping Essentials | Sleeping bags, bivouac bags
Sleeping Bags
Down, synthetic fill, or even mixed fill sleeping bags all work. Down bags are lighter and less bulky. The downside is that they take a long time to dry if they become damp.
Summer (November- April)
A "3-season bag" is suitable for comfortable sleeping at temperatures to-5°C. A down bag in this range will contain from 500 to 600 loft of fill. If bivouacs are planned for early (before mid December) or late summer (after mid-February) a 4-season sleeping bag is also suitable.
A sleeping bag liner, especially "thermal liners" can boost sleeping temperatures, and will help keep your bag clean.
Sleeping bags with a breathable water-resistant shell are ideal for short term bivouac/snow shelter situations, when used with a quality sleeping pad. They can do away with the need for a bivvy bag, except in very damp environments.
Winter (July- October)
Use a "4-season" bag, for temperatures down to -12°C.
Sleeping Pads
Only used on a bivouac or when snow camping. The huts we use have mattresses.
If you are on a course and want in to sleep in a snow shelter, please bring your sleeping mat. Choose a medium/lightweight Thermarest type, or closed-cell foam matt, 3/4 or full length.
Bivouac (bivvy) Bag
Not usually required - unless a bivouac is planned, and/or your sleeping bag does not have a water repellent shell. If you enjoy sleeping in snow shelters or under the stars a bivouac bag is a good investment.
Some sort of emergency shelter should always be kept in your backpack - such as a plastic survival bag or a “bothy” bag.
Some models of bivvy bag have non-breathable portions of fabric (e.g. nylon). These are not recommended due to potential moisture build up.
