FAQ's
-
Are the sleeping bags waterproof?
Our Wild Aspen sleeping bags are water-resistant. The durable micro-polyester shell is designed to repel light moisture and protect the insulation inside. For additional protection in wet conditions, you can use a waterproofing spray specifically designed for outdoor gear. However, it's important to ensure that your bag can still "breathe" to release water vapor while you sleep, preventing moisture buildup inside the bag. -
Which sleeping bag will best fit my height?
To determine which Wild Aspen sleeping bag is right for you, consider both your height and overall comfort preferences. The Wild Aspen 0 and 20 sleeping bags are designed with a spacious mummy shape and built-out foot box to accommodate a wide range of users. For taller campers, these sleeping bags are generously sized to ensure a comfortable fit. Check the specific dimensions on the product page to ensure the best fit for your needs. -
Do the sleeping bags have a pocket for my sleeping pad?
The Wild Aspen series does not feature a pocket for securing a sleeping pad. For added stability with your sleeping pad, consider using non-slip pads or straps to keep it in place while you sleep. -
Does Klymit use responsibly sourced down feathers?
Yes we do. At Klymit we care about our environmental impact and only use responsibly sourced feathers in our down sleeping bags.
