Alpine Luddites

White Light/White Heat


White Light/White Heat: Ice Climbing. Groveling. Screaming Barfies. If this sounds like a good time this pack is for you! It's my most popular climbing sac.

The perfect sac for lightweight alpinism, or as a seconds pack for long ice routes. If you want a top loading version, with a removable lid, check out the New Day Rising pack.

download the custom pack order form. You can see some of the most popular custom options here.

I often say no 2 packs are ever alike. the custom order form is just a starting place to design your pack around. often bag proportions are adjusted to fit your actual body shape. A customer with a short torso shouldn't be wearing the same bag shape as someone with 21'' torso. After you order a pack I'll contact you for waist belt size and any customization. You can choose from all features: waist belt, harness size, bivy pad, crampon and ice tool attachment, webbing color and size, fitting issues, etc.

  • three-point haul loops.
  • rope keeper /compression strap.
  • ITW/Fastex buckles 
  • Weight-as shown the White Light/White heat is 22 oz. but as each pack is tailored for each customer the weight can go up or down. please contact me to discuss this more.


 custom sized back length

  • sizing notes: If you plan to wear this with a harness on and climb wearing the pack, measure from where you want the bottom of the pack to sit in relation to your harness to top center of your shoulder. For normal mountaineering use I'll need the length of where you like your pack to sit on your back to the top center of the shoulder, but don't wrap the tape over your shoulder. This may not be on your waist or over your hip bone. Our padded hip belt is 3.5" wide, narrow enough to allow you to lift your legs while postholing but wide enough to help transfer so of the load. It's fully removable for climbing.
