| Short | Available in selected styles for shorter sleepers. Check the product's maximum user height. |
| Regular | The standard length option. Check the individual model's recommended maximum user height. |
| Long | Many Marmot men's and unisex Long sleeping bags accommodate sleepers up to 198 cm (6 ft 6 in). |
| Long X-Wide | Offers additional width where available. Check the individual bag's shoulder, hip and footbox measurements. |
| Women's Plus | A roomier fit option in selected women's sleeping bags. Check the model-specific dimensions. |
Important: Maximum user height and internal dimensions can vary between sleeping bag models. Always refer to the specifications for the exact sleeping bag you are purchasing.
Understanding Sleeping Bag Shapes
Mummy: A tapered design that reduces excess space and helps retain warmth. Popular for hiking, backpacking and colder conditions.
Slim Mummy: A more closely fitted mummy shape designed to minimise unnecessary space and weight.
Semi-Rectangular: Offers additional room through the body and legs, making it a comfortable option for sleepers who prefer more freedom of movement.
How to Choose Your Sleeping Bag
- Check your height: Compare your height with the maximum user height listed for the sleeping bag.
- Consider your sleeping position: If you move frequently or sleep on your side, you may prefer a roomier shape.
- Check the width: Look at the shoulder, hip and footbox measurements if you prefer additional space.
- Choose the appropriate warmth rating: Consider the lowest temperatures you expect to encounter and the bag's published temperature ratings.
- Consider packability: Weight and packed size are important when carrying your sleeping bag on multi-day adventures.
Getting the Best Fit
A well-fitting sleeping bag should allow comfortable movement without leaving excessive unused space that needs to be warmed by your body.
If you are near the maximum recommended height for a particular size, compare the next length up before purchasing.
Fit tip: Sleeping bag size is separate from temperature rating. Always check both the fit specifications and the manufacturer's published temperature information before choosing your bag.
