Our in-depth review of the Klymit Sojourn Stretch 20 sleeping bag: stretchy comfort, warmth for 3-season use, and how it compares to other Klymit bags.
When it comes to a good night’s sleep in the backcountry, your sleeping bag is just as important as your pad. The Klymit Sojourn Stretch 20 Sleeping Bag promises to deliver comfort and warmth for three-season adventures, and we’ve put it to the test. In this review, we’ll dive into its features, performance, and how it fits into your camping gear lineup.
Whether you’re a weekend car camper or a thru-hiker looking for a versatile bag, the Sojourn Stretch 20 aims to be a go-to choice. With its unique stretch fabric and thoughtful design, it’s worth a closer look.
First Impressions: Design and Materials
The Sojourn Stretch 20 immediately stands out with its stretch-woven shell. This isn’t your typical nylon ripstop; the fabric has a four-way stretch that moves with your body, reducing the feeling of being constricted. This is a game-changer for side sleepers and toss-and-turners who often feel trapped in mummy bags.
The bag is filled with synthetic insulation, which is a smart choice for damp climates because it retains warmth even when wet. The 20°F rating makes it suitable for most spring, summer, and fall camping trips, as long as you pair it with a good sleeping pad and appropriate layers.
- Stretch-woven shell for unrestricted movement
- Synthetic insulation for wet-weather performance
- 20°F comfort rating for 3-season use
Comfort and Fit: The Stretch Advantage
The standout feature of the Sojourn Stretch 20 is its stretchy fabric. Unlike traditional mummy bags that can feel restrictive, this bag allows you to bend your knees, roll over, and shift positions without fighting the fabric. The internal dimensions are generous, and the footbox is ergonomically shaped to give your feet room to move.
The hood is adjustable and works well to trap heat, but it’s not overly bulky. The draft collar is a nice touch, sealing in warmth around your shoulders. Overall, the fit is true to size, and the stretch makes it forgiving for different body types.
- Four-way stretch fabric eliminates the 'swaddled' feeling
- Generous footbox and shoulder area
- Adjustable hood and draft collar for warmth
Warmth and Temperature Performance
We tested the Sojourn Stretch 20 in conditions ranging from 40°F to 60°F, and it performed admirably. The synthetic insulation provides consistent warmth, and the draft collar does a great job of keeping cold air out. However, as with any bag, your sleeping pad plays a crucial role in overall warmth. Pairing this bag with a high-quality insulated pad like the Static V Summit Sleeping Pads will ensure you stay warm even on colder nights.
The bag’s temperature rating is honest for a 20°F bag, but we recommend using it down to about 30°F for most sleepers. In warmer weather, you can unzip the bag fully and use it as a blanket for ventilation.
- Tested comfortable in 40°F to 60°F conditions
- Pair with an insulated pad for optimal warmth
- Can be unzipped for warmer nights
Packability and Weight
Synthetic bags are typically bulkier than down, and the Sojourn Stretch 20 is no exception. It compresses into a stuff sack that’s about the size of a large loaf of bread, which is acceptable for car camping but might be a bit large for ultralight backpacking. The weight is around 3.5 pounds, making it a better choice for those who prioritize comfort over minimal weight.
If you’re looking to save space, you might consider a down alternative, but the Sojourn’s durability and wet-weather performance are worth the extra bulk for many campers.
- Compression stuff sack included
- Weight: ~3.5 lbs – best for car camping or short backpacking trips
- Synthetic insulation is more packable than some, but not as compact as down
Durability and Care
The stretch fabric is surprisingly durable, showing no signs of wear after several nights of use. The zippers are smooth and didn’t snag, which is a common issue with cheaper bags. To keep your bag in top condition, we recommend storing it loose in a large cotton sack rather than compressed.
For cleaning, spot treat stains and use a front-loading washer on a gentle cycle with a mild detergent. Be sure to dry it on low heat with a couple of clean tennis balls to restore loft. And if you ever get a tear, a simple Patch Kit can extend the life of your bag.
- Stretch fabric resists tears and abrasion
- Smooth zippers and quality construction
- Store loose; wash on gentle cycle and dry with tennis balls
Who Is the Sojourn Stretch 20 For?
This bag is ideal for campers who value comfort and ease of movement. If you’re a side sleeper, a restless sleeper, or someone who has always felt claustrophobic in mummy bags, the Sojourn Stretch 20 will be a revelation. It’s also a great choice for those who camp in damp environments where synthetic insulation is a must.
However, if you’re an ultralight backpacker counting every ounce, this might not be the best fit. Consider your priorities: comfort and versatility vs. weight and pack size. For most three-season campers, the Sojourn Stretch 20 hits the sweet spot.
- Great for side sleepers and restless sleepers
- Perfect for damp climates
- Not for ultralight backpackers
The Klymit Sojourn Stretch 20 Sleeping Bag is a standout choice for three-season camping, offering unmatched comfort thanks to its stretchy fabric and reliable warmth.
