Sea to Summit DeltaLight Tumbler

Cosy and lid from a Sea to Summit DeltaLight Mug

Filter with one of the wings cut off so it nests inside the mug, and a drawing-pin through the other to hang off the side of the mug in use. Discard the lid.

Soto Windmaster stove.

The filter doubles for coffee and loose tea. The tumbler is tritan, so makes a great beer/wine/spirits glass and an excellent tea/coffee mug.
