RAB SilTarp 3 Review: A 10 x 12 Foot Shelter at 1.4 Pounds

Introduction

The RAB SilTarp 3 is a 10 by 12 foot shelter tarp from a British manufacturer that has been building clothing and equipment for climbing and mountaineering since 1981. In the United States the brand is far less familiar than it is in the UK, where it has a strong reputation for quality gear. The SilTarp line runs across three sizes, and the SilTarp 3 is the largest of them.

At 1.4 pounds, the SilTarp 3 is unusually light for its footprint. It uses fabrics that are more often found on high-end tents than on tarps, and it packs down to roughly 9.5 by 7.5 by 3 inches. Retail price is $185, though it has been available on sale for around $140.

Who This Tarp Is For

This tarp is aimed at people who want a lot of covered space without carrying a tent. The 10 by 12 foot footprint is large enough to pitch as a lean-to, a ridgeline shelter, or a flat overhead canopy, and the size means it can protect a sleeping area plus gear in a single pitch.

Backpackers who already use a small tarp as an emergency shelter will recognize the appeal of the same idea at a larger scale. Campers who want a lightweight group shelter, or a dry space to cook and sit under, are the other obvious audience. It is less suited to someone who wants a fully enclosed, freestanding shelter with a floor.

Main Strengths

Size and Coverage

The headline number is the footprint: 10 feet by 12 feet is a genuinely large shelter, and it translates into a generous amount of dry space once pitched. In a lean-to configuration it creates a broad, deep canopy rather than a narrow strip of cover.

That size also opens up setup options. The same tarp can be pitched low and tight for wind protection, raised on a ridgeline for headroom, or strung between trees as a flat roof over a cooking and sitting area.

Lightweight Materials

The SilTarp 3 weighs 1.4 pounds, which is remarkable for a tarp this size. That comes down to the fabric choice: a 30 denier silicone treated nylon with a PU coating on the back side, plus 300 denier Cordura at the reinforcement points.

The combination keeps the bulk down while putting tougher material exactly where the stress concentrates. Packed size is about 9.5 by 7.5 by 3 inches, which is small enough to disappear into a pack. The hydrostatic head rating is 2000 millimeters, and the seams are taped.

Build Quality and Tie-Out Points

There are 21 guyline points, including a center point that allows the tarp to be hung from a tree limb. That is a lot of rigging flexibility for a shelter of this size, and it makes it easier to tune the pitch as conditions change.

Construction quality is a clear strength. Every seam and stitch is clean, with no loose threads or uneven stitching visible. A storage bag with a grab tab at the bottom is included, and the tarp is available in three colors: orange, gray, and green.

Things to Consider Before Buying

Silicone treated nylon stretches, and that characteristic is more noticeable on a large tarp than on a small one. A big panel has more fabric to sag, so expect to re-tension the pitch after it has been up for a while. The 21 tie-out points help here, since you can pull the fabric out and adjust as needed rather than living with a slack panel.

The standard version does not include stakes or guy lines. RAB also offers versions that bundle those items, so it is worth checking which configuration you are buying before you order.

Finally, this is a tarp, not a tent. It offers no floor, no bug protection, and no enclosed structure unless you pitch it that way yourself. That is the trade-off for the low weight and the large covered area.

Buying Advice

At $185 retail the SilTarp 3 sits in the upper range for a shelter tarp, and the case for it rests on the combination of a very large footprint, a 1.4 pound weight, and a pack size that is small for a 10 by 12 foot shelter. If you have priced other lightweight tarps of similar size, that combination is difficult to match.

Anyone who catches it on sale, as it has been available for around $140, gets a notably better value proposition. If you want the lightest possible emergency shelter, the smaller SilTarp 1 remains the more logical pick. If you want a lightweight shelter that can cover a real camp area, the SilTarp 3 is the one to look at.

Buy it if you want maximum covered space for minimum carried weight and you are comfortable with the quirks of silicone nylon. Skip it if you need an enclosed, freestanding shelter, or if you would rather not re-tension a pitch after the fabric stretches.

Conclusion

The RAB SilTarp 3 makes a strong case for itself on the numbers alone: 10 by 12 feet of coverage, 1.4 pounds, a 2000 millimeter hydrostatic head, and a packed size of roughly 9.5 by 7.5 by 3 inches. The 30 denier silicone treated nylon and 300 denier Cordura reinforcements put durable materials where they matter, and the 21 tie-out points give you the rigging options a tarp this large needs.

The considerations are honest ones. Silicone nylon sags and will need periodic re-tensioning, the standard version ships without stakes or guy lines, and it is a tarp rather than a tent. For backpackers and campers who want a big, light, packable overhead shelter and are willing to work with those characteristics, the SilTarp 3 is a well-built option worth putting on your shortlist.
