Hyperlite Mountain Gear's UltaMid 4 is a four-season shelter suitable for summer alpine climbs and winter ski tours. Weighing in a little over a pound this compact shelter packs small and is so light in your pack that you might not believe it's even there. Its Dyneema fabric is surprisingly resilient against rain snow and abrasion. A waterproof two-way zipper and fully taped seams enhance protection against torrential downpours to keep you and your gear comfortably dry. Dual peak vents provide airflow in warmer weather and you can open or close them for versatile coverage. There are center panel tie-outs for staking the tent down and a middle tie-out to hang the shelter from a tree if you don't have poles skis or a long stick to set up inside the tent. Hyperlite designed this shelter to fit an UltaMid 4 Mesh Insert or UltaMid Mesh Insert with DCF Floor for extra shelter from the elements.
