The Sea to the Summit Duffle Bag is a compact travel bag. We tested the 45L bag, but it also exists in three other versions 65L, 90L, and 130L. We are more in the action style, a bag for the hold, to transport kit, for trekking, mountaineering or climbing expeditions.
For this test we used the 45L in travel mode. Firstly, it looks good, compact, with quality construction, particularly around the pressure points where the straps are attached.
The Sea to the Summit Duffle Bag is made from thick tough material that resists well against abrasion. The base is reinforced with a thicker nylon layer. The only downside of course is that it is slightly heavy. The design of this sack has a slightly larger base than the top so gives great stability. The main opening is very big for optimum filling and easy fast access to all your kit. The flap stays wide open without suddenly closing on its own.
The zip is a bit stiff to start with but then slides pleasantly and opens and closes easily thanks to the help of an integrated cord handle.
In the top flap there’s a big stow pocket, but it isn’t very voluminous. What’s great about this model is that you can carry it in three different ways. There are removable straps and steel clip carabiners and anchoring points on the pack. In shoulder strap mode, the end to end straps enable comfortable carrying. In backpack mode you attach the two straps separately parallelly. This is also a comfortable way to carry the bag as the straps are well-padded. But, make sure you don’t put a pointy object or knife in the flap pocket when carrying the bag like this or you will have it stuck right in your back!
Also for the 45L model the straps are a little short for heavier builds, which doesn’t seem to be the case for the larger models. There are four handles situated around the pack on each side on the top and bottom. Two lateral compression straps enable you to compact the Sea to the Summit Duffle Bag to the maximum. They are a bit short in length.
The nylon material is waterproof, but not the zip (even if it is protected by the flap), or the stitching. The pack resists well against fine rain but isn’t totally waterproof under a downpour. This Duffle Bag is a well-designed, tough travel bag. A concept that is well-adapted to the large volume models, it just needs a bit more waterproofing. The weight/volume ratio is a little less advantageous than the big brothers. But, for its smaller volume it is easier to transport, especially in backpack mode.
It is for example an excellent climbing bag for transporting the necessary kit, and its size enables its use as hand luggage on a plane. It is quite pricy for its size, but the quality is there.
