The Sidekick Dry is YETI’s answer to a simple problem: the stuff in your pockets — phone, keys, wallet — is the stuff that gets ruined first when water shows up. This is a fully submersible, magnetically sealed pouch, built from the same class of materials as whitewater rafts, that clips into the rest of the YETI ecosystem. It comes in three sizes: 1L, 3L, and 6L.
I own all three sizes, in multiple colors. That matters for this review, because the real question with this product line isn’t “is it good” — it’s “which size, and how many.” The three sizes are not interchangeable, and buying the wrong one is the most common mistake. Here’s the honest breakdown.
The three sizes, compared
1L — Internal dimensions 24.1 × 5.7 × 14 cm. Empty weight 0.23 kg (0.49 lb). Amazon.ca price ~$50.00. Best for: pockets replacement.
3L — Internal dimensions 28.6 × 8.3 × 18.1 cm. Empty weight 0.25 kg. Amazon.ca price ~$52.00. Best for: the everyday default.
6L — Internal dimensions 34.3 × 7 × 25 cm. Empty weight 0.5 kg (1.07 lb). Amazon.ca price ~$64.00. Best for: a day’s worth of kit.
1L — the pockets replacement. Fits a phone, keys, wallet, and a trail map. This is the one for short outings, beach walks, and days when you want your essentials dry and nothing else. It is genuinely small: a large phone in a bulky case can be a tight fit, so check your phone’s dimensions before assuming it slides in.
3L — the default pick. Phone, sunblock, snacks, and a few small extras. This is the size that covers a day on the water or a long trail day without feeling like you’re carrying a bag. If you’re buying only one Sidekick Dry, buy this one.
6L — a day’s worth of kit. Fly boxes, a first aid kit, a spare layer, larger camera accessories. This is the one for fishing days, boat days, and any outing where “essentials” means more than what’s in your pockets. It has two compartments (the smaller sizes have one), which helps keep the bigger load organized. It is also the bulkiest of the three — clipped to a smaller bag, it can dominate the setup.
The buying logic: one size (3L) covers most people. Two sizes (1L + 6L) cover the extremes. All three is the full system — the right pouch for every outing, and the way to stop overpacking a small pouch or underusing a big one.
Build and durability
DryHide shell. The shell uses similar materials and construction to high-performance whitewater rafts. In practice, that means it shrugs off abrasion, scrapes, and the general abuse of being tossed in a truck bed or dragged across a boat deck. It is not a delicate pouch.
HydroShield closure. The seal is a combination of powerful magnets and an ultra-durable hook-and-loop closure. It creates a genuinely waterproof shield — YETI rates these as fully submersible, not merely water-resistant. That is a meaningful distinction: most “waterproof” pouches are splash-proof. These are dunk-proof.
RF-welded seams. The seams are welded, not stitched, so there is no needle-hole path for water. Combined with the closure, the waterproofing is the real thing, not a coating that wears off.
Interior mesh pockets. Small mesh pockets inside keep keys, cards, and small items organized instead of rattling around in one compartment. Simple, and it works.
The attachment system. This is where the Sidekick Dry earns its place in the YETI ecosystem. It can be carried on its own, attached to your belt, attached to the Sideclick Strap (sold separately), or connected to Hopper Soft Coolers, the Camino Carryall, and the Panga Backpack via the HitchPoint Grid and MOLLE system. If you already own YETI bags, the Sidekick Dry clicks straight into gear you’re already carrying.
3-year warranty. Standard YETI coverage.
What it’s great at
It is actually waterproof. Fully submersible, magnetically sealed, welded seams. Phones, wallets, and keys come out dry after real water exposure — rain, spray, splashes, and brief dunkings. That is the whole point of the product, and it delivers.
The three-size system. Most waterproof pouches come in one size and force you to adapt. The Sidekick Dry line lets you pick the right size for the outing, and the sizes are different enough that each one has a distinct job. The comparison above is the buying guide.
The ecosystem integration. The HitchPoint Grid attachment is genuinely useful, not a gimmick. Clipping the Sidekick Dry to a Hopper or a Camino means your valuables ride with the bag you’re already carrying, secured and dry, instead of loose in a pocket or rattling in a cupholder.
Durability. The DryHide shell takes abuse. These pouches are built to be used hard, and the construction backs that up.
Honest downsides
The strap is sold separately. The case alone has no shoulder strap. Out of the box, it’s a pouch — you carry it, belt it, or clip it to something. To wear it as a crossbody or belt bag, you need the Sideclick Strap, sold separately. Factor that into the price if you want a wearable setup.
Opening and closing is deliberate, not quick. The magnetic + hook-and-loop seal takes two hands and a firm press to close properly, and opening it is slower than unzipping a pouch. If you need to get into it every five minutes — checking a phone constantly, for example — the seal becomes friction. This is a pouch for things you want to stay dry, not a quick-access pocket.
The 1L is genuinely small. A large phone in a bulky case can be a tight fit. Measure first.
YETI pricing adds up. At $50–64 per pouch on Amazon.ca, buying all three sizes runs roughly $165 before the optional strap. That is a lot of money for pouches. Cheaper dry bags exist — they just don’t have the build quality, the ecosystem, or the warranty.
Magnet warning. The case contains magnets. YETI warns that placing it near a pacemaker may cause interference. Take that seriously.
Who it’s for
Boaters, anglers, beach-goers, hikers, and anyone who carries valuables near water. YETI ecosystem owners (Hopper, Camino, Panga) get the most out of it, because the attachment system turns it into a modular part of gear they already own. Dog owners who hike and paddle with a 35-pound English field gun dog like Zibi will recognize the use case immediately: the phone and keys stay dry while the dog does not.
Who it’s not for
If you need fast, repeated access to your phone, a zip pouch is quicker. If you’re on a budget, a basic roll-top dry bag costs a fraction of the price and keeps things dry enough for most outings. If you want a full bag with a strap included, this isn’t it — it’s a pouch, and the strap costs extra.
How it compares
vs. a basic roll-top dry bag (~$10–20): keeps things dry, weighs nothing, costs almost nothing. It has no structure, no pockets, no attachment system, and no warranty worth mentioning. Fine for tossing in a kayak hatch. The Sidekick Dry is the version you buy when you want the pouch itself to be gear, not just a bag.
vs. a zippered waterproof phone pouch (~$15–30): fits a phone, nothing else. Good for a beach day. The Sidekick Dry 1L does the same job with better build quality and room for keys and a wallet; the 3L and 6L are in a different category entirely.
vs. buying just one size: the 3L is the right single purchase. The 1L alone is too small for a full day; the 6L alone is overkill for a short outing. The set is the answer if you do a range of outdoor activities.
Verdict
Buy it if: you spend time near water, you already own YETI bags, or you want a waterproof pouch you’ll never replace. Buy the 3L if you’re buying one. Buy the set if you do a range of outdoor activities and want the right size every time.
Skip it if: you’re on a budget (a basic dry bag does the job for a tenth of the price), you need fast repeated access (the magnetic seal is deliberate, not quick), or you want a bag with a strap included (the Sideclick Strap is extra).
It’s expensive for a pouch. That’s the honest first sentence. But the waterproofing is real, the build quality is real, and the three-size system means there’s a right version for every outing. If you can afford it, it’s worth it — and the 3L is the one to start with.
