SAMPLEDSoulsfeng's outdoor lineup keeps creeping toward "festival survival kit"
Three foldable solar panels, a heated crossbody, a waterproof phone pouch, and a 1.68 lb sleeping bag — what actually earns a spot in the bag.
If you've been on a festival lot at 2 a.m. trying to charge a dead phone off someone's sketchy power bank, this lineup will make sense fast. Soulsfeng has quietly turned into a brand that builds for the people who actually sleep in their car between sets, and the latest drops lean hard into solar, heat, and weatherproofing. Here's what's worth knowing.
The solar trio: GreenLattice FoldX 14W, 16W, and SwiftSolar 30W
All three use the same A-grade monocrystalline silicon cells at a 20.5% conversion rate and carry an IPX6 waterproof rating, which is real-world "fine in a downpour" rather than "fine submerged." The decision really comes down to how much current you actually need.

The FoldX 14W (opens in a new tab) ($59) is the lightest of the bunch at 294g and outputs 5V at up to 2.4A through dual USB. It folds down to roughly 243×85×30mm — about the footprint of a paperback. Realistically this is a "keep one phone alive on a hike" panel, not a basecamp charger.

Step up to the FoldX 16W (opens in a new tab) ($69, down from $78) and you get 3A of intelligent voltage regulation across dual USB in a leather-wrapped case that looks more like a slim wallet than a panel. Net weight is 442g. This is the sweet spot if you only own one panel.
SwiftSolar 30W — 5V/12V output, optional USB-C variant, the basecamp pick. Photo: Soulsfeng.
The SwiftSolar 30W (opens in a new tab) ($72) is the one that actually replaces a wall outlet. It runs 5V or 12V with dual USB plus DC, or you can grab the Navy Type-C variant which adds USB-C for laptops and newer cameras. Unfolded it's 550×385mm, folded down to about the size of a hardcover, and it uses 2nd-gen ETFE one-piece lamination — the same tech serious brands like Goal Zero have shifted to because it survives flexing better than glued laminates.
Verdict
Solo traveler running a phone and earbuds? The 14W is enough. One panel for everything? 16W. Camping or van life where the panel is the primary charger for a power station, camera batteries, and a laptop? Spend the $72 on the 30W with USB-C.
ProPack-X heated crossbody bag

The ProPack-X (opens in a new tab) ($89) is the sneaky-useful one. It's a waterproof polyester sling that ships with a 5000mAh USB/USB-C power bank in the front pocket and three heating levels: 104°F, 109.4°F, and 114.8°F. Highest setting runs about 3.5 hours on a full charge. Main compartment is 35cm long and 15-25cm wide — enough for a phone, wallet, passport, keys, and a small camera. Front pocket holds earphones and the battery.
Honest take: heated bags are a niche product, but if you're shooting outdoor events in winter or just hate having freezing hands on the train, the warmth is real. It's not a sauna — it's "your front pocket isn't a popsicle" warm.
Waterproof phone bag

This is the cheapest thing in the lineup and probably the most useful. The waterproof phone bag (opens in a new tab) ($18) is a PVC pouch with a lanyard that fits phones up to 8.9 inches and comes in five colors. Camera works through the clear film, touchscreen mostly does too. Bring it to the beach, the pool, a kayak, or any festival with surprise rain. Cheap insurance.
Soulsfeng × Naturehike TrailNest sleeping bag

The collab here matters. Naturehike is one of the most respected ultralight brands out of China, and the TrailNest (opens in a new tab) ($48) leans on that pedigree. You get 320D nylon, double-stitched seams, 80g/m² imitation silk cotton fill, and a packed weight of just 0.76 kg (1.68 lbs). Open dimensions are 80.7"×33.5" — long enough for most adults. It's rated as a 3-season bag, so think spring through fall camping, not deep winter.
At $48 with a 30-day return window, this is the bag you throw in the trunk and forget about until someone needs a place to crash.
What we'd actually buy first
If you can only grab one thing: the $18 waterproof phone pouch. It pays for itself the first time it rains. If you've got real outdoor plans on the calendar, pair the SwiftSolar 30W with the TrailNest and you're set for a long weekend off-grid for under $125. The heated sling is a winter-only purchase — wait for the cold.
Bonus: Soulsfeng will take the gear back when it dies
Worth knowing before you buy anything heated or electronic — Soulsfeng runs a Product Recycling Program (opens in a new tab) on its heated shoes and clothing. Use the gear for over a year and notice the heat dropping off? You can trade it in for a discount on a new pair, scaled to how much of the product can be reused. After two to three years, send it back and the team strips and tests the electronic components for reuse instead of letting them hit a landfill.
The process is simple: email davidfeng@soulsfeng.com, WhatsApp +1 (310) 557-6230, or DM @soulsfeng on Instagram. They walk you through shipping it back, assess it, and either issue a discount code or loyalty points on your next order. For a brand selling $200+ heated boots and $139 hoodies, having a real end-of-life plan is the kind of thing that should be standard and almost never is.
