Dry Boxes for Rafting & Boating
Lockable, gasket-sealed cargo boxes that keep camp gear, kitchen kits, and electronics dry through spray, rain, and river dust — from the put-in to the takeout.
Shop SRX Dry Boxes Aluminum ChestsOn a multi-day river trip, everything you own rides in the open: strapped to a raft frame, stacked in a drift boat, or lashed in a truck bed on the shuttle. An Eylar® dry box gives that load a sealed, lockable home — a gasketed lid against splash and rain, a rigid shell that takes a beating on the frame, and padlock-ready locking points for the nights the boat sits at a ramp.

What Makes a Good Dry Box
- Gasket-sealed lids — keep spray, rain, and fine sand out of food, layers, and gear between the water and camp
- One-piece roto-molded construction — impact-grade LLDPE with no welds or seams to split or leak, flexes instead of cracking
- Lockable latches — integrated locking points secure gear at ramps, campsites, and shuttle vehicles
- Strap-down geometry — flat lids and solid walls made to be lashed to a frame, tied in a hull, or stacked in a trailer
- No rust, no rot — polymer and aluminum shells shrug off water, sun, and years of salt air
SRX Roto-Molded Dry Boxes — 50L to 175L
The core of the lineup. Each SRX is molded in one seamless piece from impact-grade LLDPE — the roto-molded cooler's toughness applied to dry storage. Gasket-sealed lids, integrated locking points, and a stackable shape that straps down cleanly on a raft frame, a swim step, or the shuttle rig's bed. The shell stays flexible in cold-water canyons and won't rust, corrode, or oxidize.

Personal dry storage: layers, headlamps, first-aid, and camp kit for one boater, at the top of the load.

Dry Box FAQs
Are these dry boxes waterproof?
They are built to keep spray, rain, and dust off your gear: gasketed lids on the SRX line and O-ring sealing on the 147L aluminum box. They are not submersion-rated — for gear that may go in the water, use an IP67 hard case inside or instead of the box.
What size dry box fits a raft frame?
Measure the bay between your frame rails first. The SRX-50 and SRX-90 fit standard frame bays and drop into most drift boat compartments; the SRX-110, SRX-175, and 147L aluminum box suit gear rafts and trailer setups. Flat lids double as a seat or a prep surface.
Can I lock a dry box?
Yes. SRX dry boxes have integrated locking points, and the aluminum chests use steel latches with padlock-adaptable hasps — add a padlock at the ramp, the campsite, or the shuttle lot.
Will a dry box rust?
No. The roto-molded SRX shells are impervious to water and UV, and aluminum does not rust. Rinse the sand off the gasket now and then and the box outlasts the boat.
