What can be stowed accommodate
27 litres total volume, 8 kg recommended load capacity, all accessible whilst running. From day hikes to multi-day fastpacking, the Trailist bridges the gap between a running vest and a rucksack.
Fits like a Running vest
Western-style shoulder straps wrap round the upper body and ensure a secure fit, even at high speeds. Made from Gridstop UHMWPE, the same material used in aramid fibre vests.
Gridstop UHMWPE is one of the most robust UL materials on the market. A high-strength polyester fabric is reinforced with a UHMWPE mesh, the same fibre used in bulletproof vests. This makes the Trailist abrasion- and tear-resistant enough to withstand sharp rock edges and bushy terrain, whilst keeping the weight to a minimum.
Made for Fast pace
The Trailist stays put where other rucksacks would have started to wobble long ago. Three scenarios in which it really comes into its own.

Frequent Questions
The short answer: Trailist when you’re running, Agilist when you’re hiking.
- Trailist: 289 g, 27 L, max. 8 kg payload. West style seat, wobble-free when running. For trail runs, fast packing, fast hut tours.
- Agilist 2026: approx. 570 g, 54 L, max. 13 kg payload. Classic hiking rucksack-seat with padded hip belt. For Alpine crossings, thru-hikes, self-sufficient multi-day tours.
For the borderline (long hut tours with moderate luggage), it's worth taking a look at our Backpack finder, which will give you a recommendation based on your setup.
The Trailist is Unisex and one size available. It suits female and male runners with a height between 162 and 190 cm.
The Western-style shoulder straps are generously sized and individually adjustable via the chest straps. A very slim or very sturdy build may affect the fit; if in doubt, write to us with your measurements, and we'll give you an honest assessment.
The lower shoulder strap pockets are on common Soft flasks up to 500 ml designed, so all standard models from HydraPak, Salomon, Naked Running, Ultimate Direction, etc.
Hard-sided bottles are also suitable, but are less comfortable whilst running. A hydration bladder is not yet compatible with the Trailist.
He is highly water-repellent, but not waterproof in the sense of a dry bag. Gridstop UHMWPE reliably repels rain and spray, whilst the roll-top closure provides additional protection for the main compartment.
For delicate equipment (sleeping bag, electronics) in persistent rain, we still recommend a dry bag or a waterproof stuff sack inside the main compartment.
Yes, the 20 L main compartment is sufficient for a typical UL setup:
- Quilt (300 to 500 g, packed approx. 4 to 6 L)
- Inflatable sleeping mat
- Bivvy bag or tarp and pegs
- Catering for 1 to 3 days
- Change of clothes, first-aid kit, headlamp
On longer trips with more provisions or a full tent (rather than a bivouac bag or tarp), the Trailist reaches its limits. In that case, it’s worth switching to the Agilist 2026.
Yes, the two chest straps (10 mm webbing, 6 g each) are fully removable and adjustable in height. You can:
- Mount both for maximum stability with a fully packed rucksack,
- Only attach one when you are travelling lighter,
- Omit both for total freedom of movement (e.g. on short trail runs).

From the end of 2026, the Trailist will be manufactured at the High-Tech Ultralight Pack partner production facility in Vietnam, with whom we collaborate. The design, development and quality control of every single rucksack take place at the Weit Läufer Lab in Emmendingen, every pack undergoes a manual check here before it is dispatched.
We also carry out repairs at WeitLäufer Lab, even years later. More details on the page Transparency and Production.
