Here are some grains of wisdom collected from consumer emails we’ve received:
How does Sea to Summit’s mesh differ from other bug netting? Is it no-see-um proof?
Sea to Summit uses a proprietary mesh: ours is polyester (which is softer than nylon), it is black (which gives better visibility than grey or white) and it has a hexagonal pattern (which means more holes per square inch than a square pattern – so you get better airflow through it)
The mesh has 500 holes / sq. in. (80 holes / cm²). The holes aren’t small enough to stop immature no-see-ums, for which reason we don’t describe it as no-see-um proof.
How do I pitch a Pyramid Shelter? Is there a floor / an entrance?
The shelters are not designed to be free-standing; their primary use is for travelers who are staying in hostels/backpacker lodges where the shelter will be suspended from the ceiling above a bed. The overlapping flap at the bottom creates a bugproof seal against the mattress or the floor (illustration shows the Double Pyramid Shelter):
The shelters can be used outdoors; in order to pitch one you would need a tree or some other overhanging object to suspend the shelter from (in the case of the Double shelter, the 22” folding pole is used as a spreader bar to provide more interior space/headroom, not to support the shelter).
Conventionally, free-standing outdoor bug shelters will have a floor and a zippered entrance (Sea to Summit shelters do not have a floor or an entrance) – outdoor shelters are therefore heavier and bulkier
How long does the Insect Shield treatment last?
Insect Shield Repellent Gear is tested and proven to last through 25 washings OR 6 months of constant (meaning daily) exposure to weathering (including rain/sun etc.)
There is no degradation in repellency when an Insect Shield treated shelter is stored. In fact, there have been a number of studies on treated items and shelf-life that resulted in no loss in repellency even after numerous years
Insect Shield has also been conducting a shelf life test since EPA registration was achieved in 2003. To date there has been no degradation in repellency.
Please note – Insect-Shield treated products are currently not available for our Canadian customers.
