Sea to Summit TPU Guide Map Case

— Show original

The packaging advertises "Made to fit A4", but the A4 only fits just barely and the corners are creased. The black borders at the top and bottom cover part of the A4. Very difficult to stuff the A4 in without creasing the paper -- probably even more difficult in "field conditions". I would have returned it, but I managed to break the retail packaging.

I've used this a couple of times in the forest while orienteering, and I haven't been able to close the pocket tightly, meaning the closing mechanism, where the thicker plastic part is pushed into the groove, only works from one side. This still works in the field, but in a canoe I would definitely want a waterproof bag, if it's promised to be one. The mechanism of the fastening cords doesn't seem to be terribly sturdy either, the fastener on one end already came loose and disappeared. Of course, it got stuck on a branch etc. while I was moving, so maybe you can't blame the manufacturer for that alone. The plastic seems to be of good quality, the case is also handy to use when folded, and I will definitely continue to use this rather than a regular plastic pocket. ** Addition, less than a week after the original review: I dropped the stars from two to one. Today in the forest, the map pocket disappeared completely, as the drawstrings had apparently failed again, even though I had tied them in several knots when the clips didn't work. I noticed too late that I only had a backpack, compass, etc., but no map bag. In other words, a pocket that couldn't be closed properly and whose lanyard wouldn't stay on. Disappointing!

Works well, good seat for kayaking.

It probably works just fine in the rain, but in super wet conditions it doesn't keep the map dry and lets water in. I would say this model is not adventure racing-proof.

Soft and foldable model, so the next thinnest model after minigrip etc. Can withstand -30 degrees. Tight opening velcro closure.

It is watertight although bit hard to open.

The map remained dry. Sometimes a bit difficult to close, especially with gloves on. Opening even more difficult.

The string that came with it is bad, and folding with Velcro is not a very good solution. But a good and waterproof pocket to which you can string many kinds of strings.

The velcro strips that keep the bag folded in two quickly stopped sticking to each other. A big bag is annoying hanging around your neck in the mountain wind when it doesn't stay folded. The closing mechanism of the bag is also rigid and quite difficult to close. Without these flaws, the bag would be really great.

It withstands folding well and when you have the patience to lay out the map carefully, it's so comfortable to use. I haven't been able to test the water resistance yet.
