A dry bag keeps things dry, but it’s one more thing to carry in your hands. The Sea to Summit Dry Bag Sling is just a shoulder strap: it clips onto a compatible Sea to Summit dry bag and turns it into a shoulder bag. It cost us $15, and we’ve used it on coastal walks and river outings.

What’s in the box
A 60 g nylon webbing strap with a padded 3D mesh shoulder section, a Field Repair ladderlock buckle to adjust the length and a rotating snap hook with a D-ring at each end, plus a small storage bag. It carries up to 9 kg and fits 2023-and-newer Sea to Summit Evac, Lightweight, Lightweight View and Big River dry bags from 5 to 35 litres. The dry bag isn’t included.

Build
The webbing is thick and doesn’t stretch, and the aluminium and POM hardware feels solid. The ladderlock is Sea to Summit’s Field Repair buckle, so you can fix it on the trail if it breaks. The snap hooks rotate, which stops the strap twisting as you walk, and the D-ring on each hook gives you a spot to clip a small carabiner.



Using It
One hook clips to the D-ring on the bag’s roll-top and the other to the lash point at the base, and it’s on in seconds. Shorten it to carry the bag by hand, or lengthen it to wear across your body. The padded section spreads the weight on your shoulder, so a full bag doesn’t dig in the way a thin strap does, and both hands stay free for a paddle or a scramble down to the water. Clipping it off again takes a little fiddling with the hooks.

Which Bags It Fits
It only works with the newer Sea to Summit dry bags that have a lash point at the base and a D-ring on the buckle: the Evac, Lightweight, Lightweight View and Big River, from 5 to 35 litres, made from 2023 on. Check your bag before you buy; older bags and other brands won’t take it.
Conclusion: Sea to Summit Sling Dry Bag RegularConclusion
The Sea to Summit Dry Bag Sling is a small accessory that makes a dry bag much easier to carry: a 60 g strap with a padded shoulder section, a field-repairable buckle and rotating hooks, good for up to 9 kg. The bag is sold separately, it only fits newer Sea to Summit dry bags and taking it off is a little fiddly, but for $15 it’s worth having if you already own one.
Both hands free.
On coastal walks and river outings it turned our dry bag into a shoulder bag that sits comfortably, and at 60 g it packs into nothing. It only fits 2023-and-newer Sea to Summit dry bags, and the bag is sold separately.

- Paddlers
- Ultralight
Yes, if you own a compatible dry bag. I paid $15 for a 60 g strap that carries up to 9 kg comfortably. It only fits newer Sea to Summit bags.
