Learn when the Front Range Bug/Floor Insert earns its place in your pack and follow a simple step-by-step setup to keep bugs and damp ground out of your shelter.

Quick answer

Use the Front Range Bug/Floor Insert when you expect wet ground or biting insects and want a dry, bug-free floor inside your Front Range Shelter. Fit it before you stake out the shelter, then pitch the shelter over it so the edges line up.

When the insert is worth the extra weight

The insert is most useful in damp, buggy conditions: marshy campsites, after rain, or summer evenings when mosquitoes are active. It adds a floor to keep you dry on damp ground and bug protection to help keep insects at bay. If you are camping on dry, insect-free ground and counting grams, you can leave it at home. The insert is designed to integrate with the Front Range Shelter, so it is not a universal fit for other shelters.

What to check before you head out

Confirm you have the Front Range Shelter, because the insert is compatible with that shelter for a secure fit. Check that the insert is clean and dry, and that you have the shelter’s stakes and poles. A common mistake is assuming the insert replaces the shelter; it is an accessory that adds floor and bug protection, not a standalone shelter.

How to set up the Front Range Bug/Floor Insert

Choose and clear your pitch: Pick a flat spot and remove sharp rocks, sticks, and debris. Common mistake: pitching over rough ground can damage the floor or make the shelter sit unevenly. A clean, level pitch protects the insert and helps the shelter set up correctly.
Lay out the insert first: Unfold the insert and position it where the shelter will go, with the bug-protection side facing up. Check that the corners and edges match the shelter’s footprint. Common mistake: laying it out after the shelter is pitched, which makes alignment harder. The insert should sit flat and centered before you add the shelter.
Pitch the shelter over the insert: Set up the Front Range Shelter directly over the insert, following the shelter’s instructions. Keep the insert edges aligned with the shelter edges as you go. Common mistake: letting the insert bunch up under the shelter, which creates lumps and gaps. Smooth the insert as you pitch so it lies flat inside the shelter.
Connect and tension the insert: Use the shelter’s compatible attachment points to secure the insert and smooth out wrinkles. The insert is designed to integrate with the shelter for a secure fit. Common mistake: over-tensioning, which can pull the insert out of shape or strain the attachments. The insert should be snug but not stretched.
Check coverage and entry: Walk around the shelter and confirm the insert covers the floor area and does not block the door or vents. Adjust as needed. Common mistake: leaving a gap near the door where bugs or damp can get in. A quick perimeter check prevents small gaps from becoming a night-long problem.
